??Shih Min is a very powerful person. He used to do research at Bell Labs and only returned to Taiwan a few years ago. He is one of the four inventors of the big mobile phone. He wrote a book on the physics of semiconductor devices, which has a circulation of about 1 to 2 million copies and has been cited in papers about 20,000 times (said to be the world's first). I just want to convey the views of a scholar with a very high status in the academic world. Mr. Shih
Min
repeatedly stressed the danger of mobile phones at a seminar on Evolution of Nonvolatile Semiconductor Memory. He cited data from current US research:
Humans will have adverse effects if they are exposed to 2mG (milli-Gauss). He demonstrated on the spot that using only instruments within the range of 10~200Hz (Hertz), the results showed that:
The mobile phone exceeded the upper limit of the instrument by 1000mG, while the microwave range used by the mobile phone is 2000, 20000Hz or higher.
The
results he measured at the national laboratory can reach 10,000~20,000 mG (milli-Gauss), which is measured during a call, not to mention being connected. The mobile phone used in this experiment is Motorola, and other brands will not be much better.
He
cited a friend in Japan as an example. He chatted with his girlfriend on the phone for more than 8 hours every day, but he hung up after the third week of continuous chatting (God). Professor Shi Min gave another example, that is, using headphones to talk on the phone. The electromagnetic wave measured next to the headphones is about 10 mG (because electromagnetic waves decay exponentially), so he made a strong suggestion:
Never use the phone to talk about love, only in an emergency. It is best not to exceed one minute, and the most important thing is: you must use headphones, not using them is simply a chronic suicide! The conscience confession of one of the inventors of the mobile phone: 1. Using a mobile phone for five years may cause cancer 2. It is better to hang the phone on the left waist than on the right waist 3. It is best not to hang it on the body, it is best to put it in a backpack 4. The smaller the phone, the stronger the radiation. 5. It is best to listen with headphones Be careful when using mobile phones, please read carefully, this is advice. Because the mobile phone uses high-frequency waves to transmit signals when receiving and transmitting signals, you can imagine it as light, just with a different frequency. The human body is made up of atoms, and each atom has an energy level. If it happens to receive such an incident wave, it will absorb energy. This is the same principle as a microwave oven, so you still have to be careful... ?? ??Just now I saw a news about mobile phones on TVBS news. The interviewee was a researcher. He said that he has a friend who does business in mainland China. He has been using a mobile phone for five years. Recently, cancer cells have appeared from the ear to the cheek. The distribution shape is the shape of a mobile phone. The surgery also "dug out" the flesh. Do you still dare to use it? The researcher also said that if you use the mobile phone for one minute, the temperature of the brain cells near the ear will rise by 1.5 degrees. Although the cells will not die, the genes in the cells will become necrotic. In addition to these, using mobile phones too much will also cause amnesia and early symptoms of Alzheimer's disease (but you won't be bald! Hehehe...). Therefore, unless it is necessary, use mobile phones less and use public phones more!! ?? ?? More and more people have mobile phones, please refer to it!! Reprinted from the Medical and Health Edition of Minsheng Daily ?? ?? Fang Jicun once had an in-depth discussion with several doctors on whether to hang mobile phones on the left or right waist. In the end, the unanimous conclusion was: the left waist is the better choice. Because there are fewer organs on the left side, even the kidneys are located in the posterior abdominal cavity, which is shielded by the intestines with stronger tolerance, and the impact is limited; on the other hand, in addition to the kidneys, the right waist also has a liver that is not very tolerant to electromagnetic waves, which is more dangerous. ?? ?? ??The following results are the relevant information that my friend and I got from the manufacturers, and the results of the experiment: ??The stronger the mobile phone reception, the stronger the source electromagnetic carrier wave, especially the mobile phone and number companies that emphasize that the signal can be received in elevators, basements, and tunnels. In order to meet the requirements of receiving signals without dead angles, these number companies or mobile phone manufacturers will cooperate with each other, such as strengthening the function of the chip on the mobile phone and the construction of base stations! However, this only allows the communication electromagnetic wave to cover a wider range and receive information, but to truly achieve clear reception, it is necessary to strengthen the electromagnetic carrier wave and radiation signal. ?? ??The smaller the mobile phone, the stronger the electromagnetic wave signal is needed to fully transmit the signal. So when you hear that someone's mobile phone is very mini, powerful, and has good reception, don't envy it. When you hear that someone can receive mobile phone signals in elevators, basements, and tunnels, don't envy it. This reveals a message: his mobile phone electromagnetic wave signal is several times stronger than yours! Think about it, how strong a signal is needed for electromagnetic waves to pass through elevator shells, underground tunnels and other reinforced concrete obstacles and then reach your mobile phone. This is like standing in front of a microwave oven without closing the door and turning it on directly. ?? ??

Not long ago, a special complainant walked into the Changchun Consumer Association. On the right half of his face, there was an obvious black mark the same size as the mobile phone. "This is also the first case of complaint about mobile phone radiation damage in Changchun." According to the staff of the Changchun Consumer Association.

Mobile phone radiation causes skin disease

Last year, Mr. Wang bought a mobile phone of a certain brand. Due to his busy business, Mr. Wang used his mobile phone very frequently, and it was common to receive thirty or forty calls a day. But after using it for a while, Mr. Wang felt that his head always hurt, and the skin on the right half of his face began to darken, and finally formed a shadow the same size as the mobile phone. Later, the doctor told Mr. Wang that it was a skin disease caused by radiation. So Mr. Wang filed a lawsuit to complain about the brand of mobile phone to the Consumer Association. But after several twists and turns, Mr. Wang had to give up the complaint. It turned out that there is no mobile phone radiation standard in China at present, and no institution that can detect mobile phone radiation has been found in Changchun. It is time-consuming and laborious to go to Beijing for testing.

Many people do not know the specific impact of radiation

. Yesterday, the reporter randomly interviewed 56 consumers. Although more than 90% of them knew that mobile phones have radiation, 82% of them did not know what specific impacts mobile phone radiation would bring. Not only that, merchants also have only a partial understanding of the harm caused by mobile phone radiation. At a mobile phone counter in a shopping mall, the reporter asked the salesperson about the radiation value of a mobile phone, and the answer she got was "The quality of the mobile phone is definitely fine, and the radiation also complies with national regulations." But she didn't know how big it was.

Changchun has no authoritative mobile phone radiation monitoring agency

. Yesterday, the reporter contacted the Jilin Provincial Electronic Information Industry Supervision and Inspection Institute and the Changchun Quality and Technical Supervision Inspection Institute. Both institutions said that there is currently no project for this test. Regarding the possible harm caused by mobile phone radiation, relevant people said that it is only limited to the discussion stage. At present, the country is actively formulating mobile phone radiation standards. The draft of "Electromagnetic Radiation Exposure Limits and Measurement Methods" has been completed and is awaiting review. It may be officially issued at the end of this year.

Regarding the possible harm caused by mobile phone radiation to the human body, an engineer at an environmental monitoring station in Jilin Province said that mobile phones mainly radiate microwaves outward through antennas. The essence of this radiation is the transmission of energy. These microwave energies have strong penetrating power. When they enter the human organs, they transmit these energies to the human organs and convert them into other forms of energy, that is, thermal effects and non-thermal effects. Since the mobile phone antenna is close to the head when in use, the emitted microwaves are very concentrated. Therefore, long-term use of the mobile phone will inevitably cause local lesions, especially affecting the human body's blood vessels and brain and nervous system.

The issue of mobile phone radiation standards has existed in China for many years. Recently, it has heated up sharply with a report from the United States, and has once again attracted widespread attention.

Motorola's "radiation scandal" draws attention

Recently, a survey report released by the Federal Communications Commission of the United States listed the 10 mobile phones with the strongest and weakest radiation. Among the top 10 mobile phones with the highest radiation values, Motorola occupied the top nine.

The news spread quickly in China, which has more than 400 million mobile phone users.

According to the data released this time, the highest radiation value of the nine Motorola mobile phones is 1.58 watts/kilogram (electromagnetic radiation test value, referred to as SAR), which is close to the upper limit of the mobile phone radiation value in the US market of 1.6 watts/kilogram, and the lowest is 1.51 watts/kilogram. Among the nine Motorola mobile phones on the "highest radiation ranking list" this time, five mobile phones have been sold in the domestic market. The "L6" that is said to have the highest radiation value is an ultra-thin straight-screen phone that was launched in China only last year and is still a best-selling model in the market.

What is the safe radiation level?

A report inadvertently sparked people's special attention to mobile phone radiation, and some domestic consumers of Motorola-related models even asked whether they should return the products.

Is mobile phone radiation harmful to the human body? What radiation value is the safe bottom line?

It is understood that China has been formulating mobile phone radiation standards for many years. Since 1997, the General Administration of Quality Supervision, Inspection and Quarantine has organized a joint working group of experts from the State Environmental Protection Administration, the Ministry of Health, the Ministry of Information Industry and other departments to discuss and formulate the "Electromagnetic Radiation Exposure Limits and Measurement Methods" (Draft).

The State Environmental Protection Administration and the Ministry of Health have proposed that only when the radiation value of a mobile phone is lower than 1.0 watt/kilogram can it be guaranteed to be harmless to the human body.

Last September, 12 research teams from seven EU countries released a three-year study on the impact of electromagnetic fields on human cells. This research institute is currently the world's largest mobile phone radiation research institute. The study found that if the radiation value of a mobile phone to each kilogram of human tissue is greater than 1.3 watts per kilogram, it will damage human DNA.

He Guili, director of China Telecommunication Technology Laboratory, said that the degree of harm to the human body cannot be judged simply by the size of the radiation value. He believes that the harm of mobile phone radiation to the human body is closely related to the individual user and usage habits. If the radiation value of a mobile phone is less than 2.0 watts/kilogram, but the user uses it continuously for a long time, it may cause greater harm to the human body than a mobile phone with a radiation value slightly greater than 2.0 watts/kilogram, because radiation has a cumulative process.

Some experts pointed out that factors that determine the amount of radiation from a mobile phone include the antenna and the design. The material and size of the antenna and the size of the mobile phone itself will affect the amount of radiation. In addition, the distance from the base station also affects the radiation. Generally speaking, the closer the mobile phone is to the base station, the less radiation it will emit.

In fact, there is not much specific evidence on how much damage mobile phone radiation can cause to the human body. The mainstream view in the medical and scientific communities is that mobile phone radiation can cause skin fever, neurasthenia, memory loss, decreased appetite, palpitations, chest tightness, dizziness, insomnia, dreaminess, immune function decline, premature aging and other symptoms.

Consumers expect standards to be introduced

As the world's largest consumer of mobile phones, China has never had its own mobile phone radiation standards. Although Chinese consumers may pay more attention to style, color, and functions when purchasing mobile phones, radiation issues have also become a factor that more and more consumers are concerned about.

Cui Liying, a mobile phone user who teaches at a university in Beijing, said that when choosing a phone model and function, she would also carefully consider the radiation of the phone. However, due to the lack of relevant knowledge and the lack of corresponding standards in China, consumers can only make judgments based on common sense.

Cui Liying said that she hopes that in the future all mobile phones will be labeled so that consumers can clearly know the radiation value of each mobile phone when purchasing.

Standards are expected to be enforced

He Guili, director of China Telecommunication Technology Labs, said in an interview with our reporter that China's mobile phone radiation standards have been completed at the technical level and were submitted to the National Standards Administration for approval at the end of last year.

Although it is not yet determined whether the final plan will be changed, and when it will be implemented, it is certain that China will finally introduce its own mobile phone radiation standards, and Chinese consumers will have standards to follow when purchasing mobile phones. In the plan submitted to the National Standards Committee, China's mobile phone radiation standard is set at 2.0 watts/kilogram, referring to the European standard, which is slightly higher than the US upper limit of 1.6 watts/kilogram.

According to He Guili, the radiation values of most mobile phone products of Chinese companies are currently lower than 2.0 watts/kilogram, so the introduction of future standards will not have much impact on domestically produced mobile phones.

It is reported that the draft of China's mobile phone radiation standard has been revised several times, and this is the first draft sent to the National Standards Committee for approval. After it is issued, it should be enforced. All mobile phone products need to pass the inspection of relevant departments and meet the standards before they can be put on the market.

Analysts point out that with the introduction of national standards and people's increasing attention to mobile phone radiation, SAR value will become a new selling point for manufacturers to promote mobile phone products. At the same time, the attention to mobile phone radiation will also give rise to a new industry - mobile phone radiation protection industry. At present, online searches have already shown products such as mobile phone electromagnetic wave eliminators and smokeless ashtrays that measure mobile phone radiation.

What is mobile phone radiation

　　When people use their mobile phones, they transmit radio waves to the base station. Any radio wave will be absorbed by the human body to a certain extent. This kind of radio wave is called mobile phone radiation. Mobile phone radiation can be divided into two types: mobile phone body radiation and base station radiation.

Testing standard for mobile phone radiation——SAR

　　SAR is the abbreviation of Specific Absorbtion Ratio, which means "absorption ratio". In layman's terms, it measures whether the impact of mobile phone radiation on the human body meets the standard.

Mobile phone radiation standards (SAR limits)

　　According to the SAR value requirements of the technical standards for measuring mobile phone radiation recommended by the International Telecommunication Union and the World Health Organization, the International Telecommunication Union standard limit is 2.0 watts/kilogram and the US Federal Communications Commission standard limit is 1.6 watts/kilogram.

Basic conclusions of international authoritative organizations on mobile phone radiation

　　Any wireless transmitting device will generate electromagnetic radiation. From this perspective, there is no such thing as a "green phone" in the pure sense.

　　The current mobile phone radiation limit stipulated by the standard is generally 50 times smaller than the radiation dose that may cause danger. Therefore, mobile phones that meet the standard are safe.

　　With the widespread popularity of mobile phones in people's lives, mobile phone electromagnetic wave radiation has become an inseparable "invisible killer " , seriously threatening human health.
　　
　　Authoritative shows:
　　research in the international medical community has proved that mobile phone radiation can cause neurasthenia, memory loss, decreased appetite, palpitations, chest tightness, dizziness, ear pain, insomnia, headaches, dreams, lack of energy, loss of libido and other symptoms.

　　Swedish famous brain tumor expert Hadel pointed out through a study of 1,617 brain tumor patients: the probability of long-term use of mobile phones to develop brain tumors, especially those who have used mobile phones for more than 10 years, is as high as 80%.

　　German scientist Dr. Andres's study on 593 eye cancer patients showed that people who often use mobile phones have three times the probability of eye cancer as those who use mobile phones less frequently

　　. Cytologist Frenzo Marinelli of the Italian National Institute and his team confirmed that mobile phone radiation can easily induce leukemia, which is probably due to the damage of mobile phone radiation to DNA.

　　French expert Charles pointed out that mobile phones are often placed on the waist of the human body, Around the abdomen, mobile phone radiation can cause unbearable damage to sperm and eggs, affect women's endocrine system, endanger reproductive function and easily cause infertility. It may also cause fetal malformation.

　　International medical institutions specially remind that mobile phone radiation is more likely to cause strong damage to the following people: heart failure, epilepsy patients, severe neurasthenia, cataract patients, pregnant women and breastfeeding women, hyperthyroidism patients, the elderly and minors whose immune systems are not yet fully developed and whose brains are not yet mature.

　　Experts point out that due to the heating effect of mobile phone radiation, the temperature of the mobile phone rises during mobile phone calls, resulting in repeated heating of the ears, face and neck skin, making the skin dry, thereby increasing facial wrinkles on women and premature skin aging.

　　The mobile phone electromagnetic wave eliminator sold by our company is a special product that weakens the excessive electromagnetic waves at the mobile phone antenna and eliminates the invalid electromagnetic waves at the receiver and microphone to achieve the protective function.

??The initiator of the experiment of boiling eggs with a cell phone was quite creative, using a cell phone to boil eggs.
?? Even if this experiment was a lie, it was so interesting that people posted comments one after another, expressing shock, suspicion, worry, anxiety, and other emotions. There were also many people who had a spirit of positivism like the reporter of the Sunday Morning News.
?? Amid the bustle around, the thing called "head" on the neck was in a state of panic: if a cell phone boiled eggs, what would happen if the noble and fragile head was sandwiched between two cell phones?
?? Here, the Sunday Morning News interviewed professors and experts in physics, electronic engineering, and neurosurgery to discuss this issue and see if the "head" should be worried?
??
?? A possible case of a cell phone "boiling" the brain
??
?? At the end of 2000, a patient from Handan, Hebei Province, walked into the neurosurgery department of the 304th Hospital of the People's Liberation Army in Beijing. His symptom was headache.
?? After a careful, detailed and thorough examination, Li Anmin, director of the neurosurgery department, told the unfortunate man a bad news - he was diagnosed with a malignant glioma. The man was shocked and couldn't believe it. He said that he had done many kinds of examinations and had never reached such a conclusion.
?? The patient didn't believe it was true and went to many other hospitals for treatment, but after two or three months, his head hurt more and more, and finally he came to the 304th Hospital of the People's Liberation Army.
?? During the examination, Li Anmin did find that the glioma in the patient's head looked very strange, which was also the reason why it was not diagnosed in many examinations. One of the strange points is that gliomas usually grow more in the frontal and temporal bones, but this patient grew behind the left temporal ear bone, which is extremely rare in clinical practice; the second strange point is that the tumor area is very large, growing diffusely and scattered, and the surrounding boundaries are unclear.
?? Because the patient's tumor has a special shape, Li Anmin specially investigated the cause of the disease to understand what caused this disease. The patient thought about it and asked if it was related to the mobile phone. The patient was in charge of engineering construction in the company. He used his mobile phone very frequently. He had been using mobile phones since the days of the mobile phone, which means he had been using mobile phones for about 8 years. More importantly, he had a habit of using his mobile phone, and liked to answer calls with his left ear and write with his right hand. The tumor was on the left side of his head, which was the radiation area of the mobile phone antenna.
"There is a microwave transmitter near the head of the mobile phone, which is equivalent to cooking the brain." Li Anmin thought so. The
patient was treated in the hospital for two years, but unfortunately died of the spread of cancer cells. The first view: "Mobile phone radiation is definitely harmful" Although it is still an inconclusive statement whether mobile phone radiation is harmful to the human body, Li Anmin, director of the Department of Neurosurgery of the 304th Hospital of the People's Liberation Army, said that from the perspective of a doctor or environmentalist, mobile phone radiation is definitely harmful. Perhaps because he came into contact with a patient who was suspected of having a brain tumor due to long-term use of mobile phones in his work, his view is more firm. ?? Regarding the experiment of boiling eggs with mobile phones, he believes that this possibility exists because it makes sense in principle. He explained to reporters: mobile phone radiation can trigger high oscillation waves, which is like shaking water in a sealed can continuously. The oscillation waves generated are very strong and can generate a lot of heat energy, which may cook the eggs. ?? Similarly, the heat energy generated by mobile phone radiation can penetrate the skin and directly point to human cells, thereby causing cell deformation and breakage. If exposed to such radiation for a long time, cells will become diseased and cause tumors. ?? Li Anmin pointed out that there are many experiments on mobile phone radiation abroad. For example, a professor at the University of Washington in the United States once exposed 50 mice to microwave radiation similar to that of mobile phones, and found that these mice affected by radiation almost all lost their memories compared to those not affected. However, there are relatively few related experiments in China. Li Anmin said that their team is planning to use single-celled animals nematodes to conduct a related experiment. He introduced that after irradiating nematodes, it is possible to see that the proteins in the nematodes will produce similar effects of thermal shock, just like being slightly boiled. ?? Turning from the topic of boiling eggs with a cell phone to boiling the brain with a cell phone, Li Anmin pointed out that although there is a risk of brain tumors caused by cell phone radiation, there is no possibility that the heat generated by cell phone radiation will cook the brain, because the human body has blood, which takes away the temperature like lubricating oil. He also gave some warnings about the use of cell phones at the end - use less, wear headphones when using, and choose good brand headphones. ?? Xiao Gaobiao from the Department of Electronic Engineering of Shanghai Jiaotong University also explained to reporters the principle of cell phone radiation: cell phone radiation is a kind of microwave radiation. When using a cell phone, microwave radiation will heat and vibrate biological tissues, which has a greater impact on the human eye and reproductive system. In January 2001, a German study found that cell phones may cause eye cancer, because they compared 3,000 people with eye cancer and 3,000 normal people, and people who often use cell phones have three times more chances of developing eye cancer than others. At the same time, Xiao Gaobiao reminded that in places where the signal is weaker, the cell phone must increase the transmission power, resulting in greater cell phone radiation. ?? ?? The second view: The key lies in the "dose" ?? ?? Professor Chen from the Department of Physics, East China Normal University, who teaches physiological electromagnetism, first used a series of calculations to prove to reporters the impossibility of using a mobile phone to cook an egg: ?? It takes 1 calorie of heat to raise the temperature of 1 gram of water by 1°C. Assuming that it can be heated to 80°C, then 50 calories of heat are needed to heat the temperature from the current 30°C to 80°C. If an egg weighs 100 grams, and assuming that the amount of heat required to heat it is the same as that required to heat water, then 5,000 calories of heat are needed. Based on the physical formula, it is concluded that more than 20,000 joules of power are required. Dividing this power by the one hour required for the experiment, it is roughly estimated that 5 joules/second, or 5 watts, are required to cook an egg. And these do not take into account the heat emitted by the mobile phone to the surrounding area during a call. However, current mobile phones cannot reach 5 watts, so it is almost an "impossible task" to use a mobile phone to cook an egg. ?? Professor Chen believes that it is difficult to say whether mobile phone radiation is harmful to the human body, because mobile phone radiation is electromagnetic waves. It is certain that electromagnetic waves have an impact on the human body, but it is difficult to say whether it is a positive effect or a negative effect. The key lies in the "dose" issue. In fact, the space we live in is inseparable from electromagnetic waves, because electromagnetic waves are needed to receive calls and radios. These electromagnetic waves surround us, which is not a terrible thing, because they are very weak. ?? Professor Chen used a popular analogy to illustrate his point of view. He said that mobile phone radiation has an impact on the human body in a short period of time. It is like being hit by someone. It will not hurt after a while, but if you are hit all the time, it will have an impact for a long time. Moreover, mobile phone radiation is related to the physique of different people. This is a very complicated issue. ?? Regarding the question raised by the reporter whether the heat generated by mobile phone radiation will cook the brain, Professor Chen pointed out that there is no need to worry, because the human body will exchange energy with the outside world, and will dissipate all this energy in contact with the air. Only when the heating energy is greater than the heat dissipation energy can it be possible to cook things, such as microwave ovens, which are tools that emit high heat. ?? Professor Chen admitted that some experiments did show that mobile phone radiation has an impact on lower organisms, but more experiments did not show such an effect, so the academic community has not reached a conclusion on the matter. However, Professor Chen still tends to believe that as long as the dosage is controlled, there is nothing to worry about. ?? ?? The third view: There is no conclusion at all ??






















?? Zhu Wei, a doctor from the Department of Neurosurgery at Shanghai Zhongshan Hospital, is neither sure nor negative about whether mobile phone radiation is harmful to the human body. He cannot express a clear attitude because nothing has been concluded.
?? Zhu Wei mentioned that the United States, Sweden and other countries have conducted experiments on the harm caused by mobile phone radiation, but there are still no large-scale experiments and there is no conclusion in the academic community. There are only a few individual reports on the harm of mobile phone radiation to the human body. For example, after a patient developed a brain tumor, the doctor suspected that he had used a mobile phone for more than ten years and the brain tumor was related to mobile phone radiation; there are also people who are used to using their left ears to make calls, and finally developed a brain tumor on the left side of the brain. But Zhu Wei believes that such reports on single events cannot fully explain the problem.
?? So far, there is no clear correlation between mobile phones and brain tumors, but many unknown potential harms are difficult to explain clearly. Before there is a clear conclusion, Zhu Wei finds it difficult to give an opinion. However, he said that there are no clear disadvantages of mobile phone radiation, but there are definitely no benefits.
?? Speaking of the experiment of boiling eggs with a cell phone, Zhu Wei believes that it can attract attention, but the eggs still cannot explain a big problem, because the radiation will definitely increase when docked, but we usually don't put two cell phones on both sides of our ears to make calls.
?? When Zhu Wei was interviewed, he had just returned from the United States. He observed that Americans also use cell phones more frequently in the United States, but not as frequently as we use them here. Many Americans still use pagers. Before the conclusion of whether cell phone radiation is harmful to the human body is reached, Zhu Wei thinks that cell phones should be used as little as possible, and using headphones can also help. At the same time, he reminds people not to put cell phones in fixed positions on their bodies.
?? Xu Xiong from the Department of Electronic Engineering at Shanghai Jiaotong University also believes that it is still unclear whether cell phone radiation is harmful to the human body, but he will try to pay attention to the use of cell phones in daily life. He himself will not put his cell phone on his waist or in the pocket on the chest of his shirt. In places with weak signals, he will try to reduce the call time as much as possible, because the signal is weak, and the cell phone increases the transmission power to enhance the sensitivity, which will increase the radiation.

?? In modern society, mobile phones have become an indispensable communication tool for many people. Not long ago, a survey and statistical report by CNET showed that Motorola mobile phones generally have high radiation, occupying eight of the top ten radiation values on the market. This incident has aroused great public concern about the harm of mobile phone radiation. After the basis of the radiation standard was reported, many consumers expressed concerns about mobile phone radiation, and some consumers even said they would return the Motorola mobile phones they had bought. It is understood that there are currently no mandatory regulations on the peak value of mobile phone radiation in China. Because the "Electromagnetic Radiation Exposure Limits and Measurement Methods" (Draft) has not yet been issued, there are no clear legal provisions in China to stipulate mobile phone radiation standards.
?? For the test of mobile phone radiation, the current internationally accepted standard is: with a time of 6 minutes, the SAR value of the mobile phone's radio frequency exposure shall not exceed 2w/kg (that is, the electromagnetic radiation energy absorbed by each kilogram of brain tissue shall not exceed 2w). This standard is currently the common standard in the international industry, but there are still many people in the industry who regard measuring the peak power emitted by the mobile phone as a test of whether the mobile phone radiation meets the standard, forming a misunderstanding. Some people also believe that the radiation consumers are exposed to when using mobile phones mainly depends on the power control of the base station on the mobile phone.
?? Because there are so many mobile phone users, even a small impact of mobile phones on the human body will attract public attention. Different mobile phones have different exposure SAR values, which can easily lead to concerns and misunderstandings among consumers. Several views on mobile phone radiation in the industry
?? At present, international authoritative organizations have not yet formed a unified understanding of the issue of mobile phone radiation. The debate on whether mobile phone radiation is harmful to the human body is still quite intense in the industry.
?? Viewpoint 1 is purely groundless worry
?? Dr. Alan Prey, the head of the British research project, said that the research team he led has begun to study the impact of microwaves on blood circulation, but there are no signs of danger at present.
?? Researchers at Chalmers University in Sweden conducted experiments and studies on humans and animals and found no evidence that using mobile phones is prone to cancer. There was public opinion that people who use mobile phones are 2.5 times more likely to develop brain cancer than those who do not use mobile phones. But researcher Molde said that his research results show that this phenomenon does not exist.
?? Viewpoint 2: 1.3 watts/kg or more is harmful
?? In September 2005, 12 research groups from 7 EU countries released a survey on the "effects of electromagnetic fields on human cells" that took three years to complete. This research institute is currently the world's largest mobile phone radiation survey. The study found that if the radiation from a mobile phone to each kilogram of human tissue is greater than 1.3 watts/kg, it will damage human DNA. However, China's health department stated that only when the mobile phone radiation value is less than 1.0 watts/kg can it be guaranteed to be truly harmless to the human body.
?? Viewpoint 3: The impact of radiation varies from person to person
?? He Guili, director of the Telecommunication Research Institute of the Ministry of Information Industry, believes that the problem of mobile phone radiation should be "different for different people". For different people, the impact of mobile phone radiation is not the same. He said that from the perspective of electromagnetic science, mobile phone radiation definitely has an impact on the human body, but "just like some people will have skin allergies when exposed to the sun while others will not, people's sensitivity to mobile phone electromagnetic radiation is completely different, and there are great individual differences."
?? He Guili said that if you feel hot, dizzy or even painful on your head after talking on the phone for a while, it means that you are very sensitive to the electromagnetic radiation of mobile phones, so you must use your mobile phone as little as possible or insist on using headphones. But some people don't feel anything even if they talk for one or two hours, so they may be insensitive and can use it with confidence. In addition, he also emphasized that the use of mobile phones must be done in a proper way, so as to minimize the negative impact of mobile phone radiation. Tips for preventing mobile phone radiation
?? Each mobile phone has different degrees of radiation. Here are some tips and precautions for mobile phone "anti-radiation", which I believe will be helpful to everyone.
?? Wait 1 second before answering the phone
?? Generally speaking, the radiation of a mobile phone is small when it is on standby, and larger when it is on a call, and larger when the mobile phone number has been dialed but not yet connected. The best way is to put the phone close to your ear 1 second after it is connected.
?? Reduce use when the signal is too poor
?? In order to obtain better call quality in places with poor signals, some mobile phone manufacturers often increase the electromagnetic wave emission intensity of mobile phones when designing mobile phones. When the signal is only one bar, the transmission intensity of the mobile phone signal may be 1000 times greater than when the mobile phone signal is full. Experts suggest that if the signal is not good during a call, you can adjust the direction of the mobile phone antenna back and forth, or pull out the antenna. If the signal is still not good, do not talk for a long time, or try to use headphones.
?? Don't put it next to your pillow when sleeping
?? Experts say that mobile phone radiation has the greatest impact on the human head. Therefore, do not chat on your mobile phone for too long, and do not put your mobile phone next to your pillow when sleeping.
?? Don't use your mobile phone as a chest ornament
?? Many people like to hang their mobile phones on their chests because it is convenient to use. Moreover, mobile phone styles are becoming more and more fashionable, and many girls like to use their mobile phones as ornaments. However, studies have shown that hanging a mobile phone on the chest will have a certain impact on the heart and endocrine system. Even in the standby state with less radiation, the electromagnetic wave radiation around the mobile phone will affect people with heart failure and arrhythmia.
?? It is best not to put it in your pants pocket
?? Medical experts point out that if a mobile phone is often hung around the waist or abdomen of the human body, the electromagnetic waves generated when it sends and receives signals will radiate to the sperm or eggs in the human body. Therefore, mobile phone users should try to keep their mobile phones away from the waist and abdomen, and do not hang the mobile phone on the waist or put it in the pocket of a coat. When users are in the office, at home or in the car, it is best to put the mobile phone aside. When going out, you can put the mobile phone in a purse.

?? No matter how fierce the controversy over whether mobile phones are harmful to the body, almost every expert admits that mobile phones have a certain amount of radiation. The focus of the current scientific debate is how much impact this radiation has on people and whether it will endanger human health? Please pay attention———
??　　
??
?? The dispute between the two factions has a long history
??
?? At present, the controversy over whether mobile phone radiation is harmful mainly focuses on the statement "whether mobile phone radiation can cause brain tumors", and the dispute between the two factions has been endless since the first confrontation. Earlier this month, a report from the Swedish National Institute for Working Life Research also discussed this issue. Scientists selected 2,200 tumor patients and the same number of healthy people, and then compared their use of mobile phones and wireless phones. The results of the survey show that frequent use of mobile phones or wireless phones will greatly increase the risk of brain tumors.
??
?? Although there have been many cases in the world where brain tumor patients have taken mobile phone manufacturers to court, no clear conclusion has yet been reached.
??
?? The author roughly counted that since the American man who first criticized mobile phone radiation in 1993, there have been more than 200 authoritative conclusions.
??
?? In this regard, Li Anmin, chief physician of the Department of Neurosurgery of the 304th Hospital of the People's Liberation Army, said: The harm of mobile phone radiation to the human body is objective. The main mechanism of mobile phone radiation is: the high oscillation waves caused by radiation (about 1,000 oscillations per minute) generate a large amount of heat energy, which penetrates the skin and directly points to human cells, thereby causing cell deformation and fracture. If exposed to such radiation for a long time, cells will become diseased and cause tumors.
??
?? Prevention is far more effective than controversy
??
?? Regardless of whether mobile phones cause brain tumors, there is no doubt that mobile phones have radiation. So, should we not use mobile phones? Li Anmin said: "It is not realistic and necessary to ask modern people not to use mobile phones. It is just to use them as little as possible and pay attention to scientific methods of use. Scientific use of mobile phones can enable the human immune system to clear or repair itself. In layman's terms, if only a few cells are damaged by radiation, the human immune system will promptly discover and 'eat' or 'cure' them, and this process is going on all the time."
??
?? However, Li Anmin also warned: "Everything has a degree of change, that is, there is a process from quantitative change to qualitative change. If you use your mobile phone for more than three or four hours at a time, or make or receive calls on your mobile phone more than ten times a day, it may cause damage to the immune system. A single large dose of electromagnetic radiation or long-term low-dose radiation will exceed the monitoring and repair capabilities of the human immune system. Once the human immune system cannot function, human cells will undergo irreversible distortion, the distorted cells will proliferate disorderly, and malignant tumors will be generated."
??
?? Zhang Xianhuai, spokesman for the Department of Neurosurgery at the PLA 304 Hospital, pointed out: "Although there is controversy over whether mobile phone electromagnetic radiation can cause harm to the human body, it is always beneficial to health to prevent problems before they happen and reduce the exposure of radiation to the human body."
??
?? An expert from the China Consumer Electronics Association said: There are not many complaints about mobile phone radiation in China at present, and there is no authoritative testing agency to make fair judgments in this regard. There are many people with strong health awareness abroad who often sue. From the current situation, the opinions of the testing agencies commissioned by mobile phone manufacturers and neurologists have formed a fierce collision, but no conclusion has been reached. Therefore, prevention is far more effective than debate under the current situation.
??
?? Mobile phone radiation standards are expected to be issued this year
??
?? At present, there is no unified standard for mobile phone radiation standards in the domestic market, which makes mobile phone manufacturers have no reference standards. It is understood that the relevant national departments are currently actively negotiating the "Electromagnetic Radiation Exposure Limits and Measurement Methods" (draft), and this draft will be launched later this year.
??
?? Professor Li Shufang of Beijing University of Posts and Telecommunications said: "Domestic telecom operators only pay attention to the call quality, and leave all mobile phone radiation to the health and environmental protection departments. As a result, the opinions of all parties on mobile phone radiation in the past few years are quite different. Now that the "Electromagnetic Radiation Exposure Limits and Measurement Methods" has been formulated, the opinions of all parties may be coordinated."
??
?? Li Shufang also said: "The size of mobile phone radiation has a relatively complete set of standards in the international scientific community. The amount of radiation that an organism is allowed to absorb per unit kilogram is the SAR value, or "specific absorption rate". The lower the value, the less radiation is absorbed. The SAR value standard in most European countries is 2W, and in the United States it is 1.6W. China's "Electromagnetic Radiation Exposure Limits and Measurement Methods" (draft) to be issued will adopt the European standard with a slightly higher SAR value. In any case, standards mean regulations."

??
?? 1993: The first to start the dispute was a man from Florida, USA. In an interview program hosted by Larry King, a famous American TV host, he said that his wife had a brain tumor due to using a mobile phone that did not meet the safety indicators, and he was preparing to "ask for an explanation" from the relevant company. Once the program was broadcast across the United States, it immediately attracted a lot of echoes.
??
?? January 15, 2001: A German study found for the first time that mobile phones may cause eye cancer, because they compared 3,000 people with eye cancer and 3,000 normal people, and people who often use mobile phones have a three times higher chance of developing eye cancer than others.
??
?? September 2004: The National Radiation Protection Bureaus of the five Nordic countries issued a joint statement saying that there is no scientific evidence to prove that mobile phones harm human health, but it is worth promoting to minimize exposure to radiation.
??
?? March 10, 2005: 12 research teams from seven EU countries conducted a three-year study on the impact of electromagnetic fields on human cells. Experts determined that mobile phone radiation may damage human genetic information.
??
?? April 12, 2005: An article in the Journal of the American Academy of Neurology announced: "Danish scientists have confirmed that there is no direct link between the use of mobile phones and brain tumors." Because Danish scientists obtained the mobile phone users' mobile phone usage time records from telecommunications companies, and conducted a study and analysis on 427 brain tumor patients and 822 mobile phone users without brain tumor diseases. The results showed that the risk of brain tumors has nothing to do with mobile phones.
??
?? January 20, 2006: Patricia, a professor at the University of Leeds, published an article in the British Medical Journal stating that there is no connection between the risk of glioma and factors such as frequent use of mobile phones, cumulative mobile phone usage time, and the number of phone calls.
??
?? April 10, 2006: The latest research by the Swedish National Institute for Labor and Life found that long-term and heavy users of mobile phones may have a 2.4 times higher risk of developing malignant brain tumors on the side of the head where they usually listen to the phone. Frequent use of mobile phones for more than 10 years will increase the risk of malignant brain tumors by 3.7 times, while starting to use mobile phones before the age of 20 will increase the risk of brain tumors by 3.1 times.

The problem of cell phone radiation has been recognized by everyone for a long time, but it seems that it is not as serious as you think. It is OK as long as the time is not long. Cell phones are small microwave transmitters, and the way they harm people is like microwave ovens heating food, and high-frequency vibrations can damage some tissues of the human body.

Of course, mobile phones have radiation, so you have to protect yourself. It is best to turn off the phone before sleeping. Even if you cannot turn it off, you should put it away from your head. When you are on the phone, don't rush to put it to your ear when the call is not connected. In terms of diet, you can eat more sea fish, sunflower seeds, kelp, etc. to absorb radiation, and you can drink more green tea.

?? When the slogan "Health is the first element of life" has been deeply rooted in people's hearts, cancer prevention and radiation protection have become another popular element, but people have ignored many hidden dangers buried around them. For a long time, experts have continuously pointed out the harm of mobile phone radiation to the human body, but how serious is this harm? Is it within the body's tolerance range? Will long-term use of mobile phones cause diseases to the human body?
??
?? On March 9, 2006, CCTV 10's "People" column interviewed Li Anmin, director of the Department of Neurosurgery of the 304th Hospital of the People's Liberation Army. According to Professor Li, there are many severe cases caused by mobile phone radiation abroad, but few have been found in China so far. However, mobile phone microwave radiation can indeed cause neurasthenia, palpitations, chest tightness, dizziness, lack of energy and other symptoms, and even cause malignant brain tumors.
??
?? This statement is undoubtedly "a stone that stirs up a thousand waves" for the hundreds of millions of people using mobile phones in China. Who is Li Anmin? What made him confidently disclose this "suspense topic" that has long been claimed by all media to be "unconclusive" in front of the people of the country?
??
?? Li Anmin, currently the director of the Department of Neurosurgery of the 304th Hospital of the General Hospital of the People's Liberation Army, is unique in the diagnosis and treatment of brain trauma, brain tumors and epilepsy. He has also made breakthroughs in the treatment of brain malignant tumors, and has created advanced technologies for intratumoral radiotherapy and chemotherapy of brain tumors, obtained two national invention patents, and expanded selective and super-selective cerebral artery interventional chemotherapy methods, which have achieved positive therapeutic effects.
??
?? Professor Li's connection between mobile phone radiation and brain tumors comes from a case of malignant glioma he disclosed in the program. The case was published in a newspaper in the south in the fall of 2002, which attracted widespread attention from the society at that time. The patient who shocked and attracted the attention of the whole country was 38 years old and had been treated in two famous hospitals in Beijing, both of which were diagnosed with cerebral infarction. However, the conclusion drawn by Li Anmin and other experts in the consultation was a malignant tumor. Li Anmin found that this patient not only frequently used his mobile phone, but also always placed his mobile phone at the position of his left ear to answer calls. Moreover, the location of the mobile phone antenna just corresponded to the location of the brain tumor lesion. After several animal experiments and diagnosis, comparison and elimination, Li Anmin confirmed that the high frequency of mobile phone use was the root cause of this malignant brain tumor case. As a result of this disclosure, Li Anmin also became the first person in China to point out to the media that mobile phones are harmful to the human body.
??
?? Although this program on CCTV 10 is in the form of a personal interview, it has sounded the alarm for all those who use mobile phones, especially those who frequently use mobile phones to answer calls. In fact, as early as a few years ago, there were a series of claims that mobile phones are harmful to the human body - mobile phone radiation damages brain cells, destroys human genetics, causes infertility, causes eye cancer, etc., but these seem so insignificant when written on paper, and no one really realizes how to protect themselves from their surroundings and keep themselves away from harm. When the iron-clad facts are in front of us, coupled with the evidence of authority and experts, we gradually begin to pay attention to the hidden dangers around us.

?
?? A few days ago, the Federal Communications Commission (FCC) of the United States released the global mobile phone radiation rankings, listing the ten mobile phones with the highest radiation, of which eight Motorola models were named. Coincidentally, as early as April 21, the Russian KP website reported an experiment of "cell phone boiling eggs" conducted by three researchers, and the results of the experiment were very shocking.
??
??
??
?? The experiment boiled eggs through the process of mobile phone calls. First, an egg was placed in a ceramic cup (easy to conduct heat), and then two mobile phones were placed on both sides of the egg.
Then the call was made. In the first 15
minutes , the egg did not seem to have any obvious changes. When the call was carried out for 25 minutes, subtle changes occurred. The eggshell began to heat up. At 40 minutes, the surface of the egg began to become more brittle. After the experimenter cracked it open, he found that the egg white inside had become solid, but the yolk was still loose. So he continued to the experiment for 65 minutes. At this time, the whole experiment ended. The experimenter took the egg and found that it was fully cooked. ?? ?? ?? ?? Postscript: Although the test results are terrible, there is no complete conclusion on whether "mobile phones will cause greater harm to the human body", so please don't panic.

??
?? In last year's Lunar New Year film "Cell Phone", Zhang Guoli played the role of program planner Fei Mo, who denounced mobile phones as "troublesome!" This year's mobile phone problem has escalated again: from "troublesome" to "endangering health". According to the latest report from Germany's Bild, EU scientists recently announced an astonishing research result: mobile phone radiation can damage the DNA containing genetic genes in the human body, thereby endangering the health of mobile phone users and even their next generation, and even causing cancer in severe cases.
??
?? Mobile phone radiation damages DNA and may cause cancer
??
?? Is mobile phone radiation harmful? If it is harmful, how serious is it? Experts have been arguing about this for many years. Recently, 12 research teams from 7 European countries worked together and finally confirmed that: at least in the laboratory, mobile phone radiation can cause obvious damage to human DNA. "We will conduct further research, mainly to conduct similar tests on volunteers outside the laboratory to confirm that mobile phone radiation will damage DNA under any circumstances," a researcher from the team announced. The research project is mainly funded by the European Union and is headed by Professor Franz Rudiger from Vienna.
??
?? "Please don't take risks with your health. If possible, try to use your mobile phone as little as possible; if you have to use it, it is best to use headphones, so that at least the radiation will not directly damage the brain." Professor Rudiger solemnly suggested, "We don't want to cause panic, but it is necessary to prevent it in advance."
??
?? Rudiger emphasized: "Because DNA is damaged, the harm of mobile phone radiation will naturally continue to the body cells of the next generation." And many people already know that when cells are damaged, they will mutate, which is one of the main causes of cancer.
??
?? Because it is related to the health and happiness of too many people, Professor Rudiger and his researchers are particularly cautious. They announced that they will extend the study for another 4 to 5 years in order to obtain more comprehensive and authoritative research results.
??
?? Six major mobile phone manufacturers have not made a positive response
??
?? Once the research results of Rudiger and others were published, they had a huge impact all over the world. By the end of June 2004, the total number of mobile phone users in the world had reached nearly 1.5 billion, so this research is related to the health of about a quarter of the world's population. So far, the world's six major mobile phone manufacturers have not made a positive response to this latest research result. Only one German manufacturer recently announced that the manufacturer is about to launch a new mobile phone, and they particularly emphasized that this mobile phone will not produce harmful radiation to the human body.
??
?? In fact, in recent years, there have been a number of research reports on the health hazards of mobile phone radiation. For example, a Swedish research team found that mobile phone radiation can actually soften the brain tissue of mice and form cavities on the surface of their brains; and mobile phone radiation can cause protein deposition in the human body, which in turn induces early Alzheimer's disease. Some other studies have pointed out that mobile phone radiation can increase the temperature of human skin and cause dizziness or nausea. But mobile phone manufacturers have responded quickly to these conclusions, insisting that there is no obvious evidence to prove the harm of mobile phone radiation. But this time, facing the research results of 12 European research teams that took three years, no one dared to comment or even refute it easily.
??
?? Chili can prevent mobile phone radiation
??
?? Many people will say: "I have used mobile phones for so many years, and nothing happened." In this regard, Gabel, a scientist at the University of London, pointed out that the harm of mobile phones has a long incubation period, and it is difficult for people to see the consequences at once, which makes many people turn a blind eye to the harm of mobile phones.
??
?? In addition to using mobile phones as little as possible, researchers have also proposed some ways to reduce radiation hazards, mainly the following:
??
?? First, the radiation when the mobile phone dials is particularly large, especially when the number has been dialed but not yet connected, the radiation is about 3 times that of standby, so try to keep the mobile phone away from the body when dialing; secondly, do not put the mobile phone next to the pillow, women should not hang the mobile phone on the chest, and men should avoid hanging it on the waist; finally, it is best to turn off the phone when not in use.
??
?? In addition, some experts have also proposed very novel views. For example, drinking green tea can reduce the harm of mobile phone radiation, because medical evidence shows that green tea can effectively prevent radioactive substances from invading human bone marrow; in addition, eating vegetables and fruits can also adjust the impact of radiation on the human body.
??
?? The most surprising thing is that experts say that peppers can also prevent mobile phone radiation. As we all know, peppers can be used to sterilize and disinfect. In fact, peppers are also a natural secret weapon against mobile phone radiation! Peppers are a kind of spice. The latest scientific research has found that it can protect the DNA of cells from being damaged by radiation. Therefore, people can reduce the harm caused by mobile phone radiation by eating more spices such as red peppers, black pepper, and curry. (Zhan Xiao)

?? "If your child is under 8 years old, it is best not to let your child play with a mobile phone!" Recently, the National Radiation Protection Committee of the United Kingdom issued a report on "Mobile Phones and Health", saying, "Although there is no conclusive evidence that the use of mobile phones will pose a threat to public health, due to its uncertainty, the public should use mobile phones with caution before further results come out."
??
?? According to the report, children may be more susceptible to the impact of mobile phones because their nervous systems are developing. "The widespread use of mobile phones may have negative effects, but they will not appear until a few years after use. Recently, there have been reports linking mobile phone use with ear tumors, and there are also reports that mobile phone radiation may disrupt the physiological system. Although there are no final results, if it becomes a fact, children will be more affected than adults." Stewart, chairman of the National Radiation Protection Safety Committee of the United Kingdom, warned.
??
?? "Regarding mobile phone technology, our committee is very concerned about its impact on public health. The fact is that mobile phones have become part of daily life and even become a fashion accessory for some people, but it cannot be said that it is safe just because people are using it." Stewart said.
??
?? Yesterday afternoon, Shi Denian, chief engineer of China Telecommunication Technology Laboratory, an authority on mobile phone radiation testing, said in an interview with a reporter from the Morning Post: "Any manufacturer producing any model of mobile phone must undergo our laboratory's mobile phone radiation testing before entering the Chinese mobile phone market. Only those that meet the standards can enter the market." Chief Engineer Shi Denian suggested that although there is no clear conclusion on whether mobile phone radiation is harmful to human health, users should use mobile phones with caution, use landlines as much as possible, and use headphones as much as possible. It is reported that the radiation limit specified in the current standards is generally 50 times smaller than the radiation dose that may cause danger. As long as it does not exceed the recognized standards, its impact on the human body is very weak. (Xu Huifen)

?? Recently, a case of malignant tumor in the First Affiliated Hospital of the General Hospital of the People's Liberation Army has once again aroused the media's debate on whether mobile phone radiation is harmful to the human body. According to Professor Li Anmin, director of the hospital's neurosurgery department, this is the first case reported in China of a tumor caused by long-term use of mobile phones.
??
?? At the end of 2000, Professor Li admitted a patient with a large-scale glioma in the left cerebral hemisphere. After diagnosis, the doctor determined that the patient had induced a brain tumor due to long-term and high-frequency use of mobile phones. There are three reasons: the tumor has a special shape, the patient's tumor grows diffusely and scattered, and the surrounding boundaries are unclear; the patient's tumor occurs at the junction of the temporal parietal occipital area, which is extremely rare clinically; the patient has been using a mobile phone for 8 years and is accustomed to answering the phone with his left hand. The tumor area is on the left side of the head, which happens to be the radiation area of the mobile phone antenna. In the end, the patient died of the spread of cancer cells.
??
?? According to Professor Li, there are many severe cases caused by mobile phone radiation abroad, but few have been found in China so far, but brain tumors caused by mobile phone radiation are all malignant. "The thermal effect of microwave radiation will damage brain cells, which is equivalent to 'cooking' the brain."
??
?? Di Guoqing, a visiting researcher at the Shanghai Institute of Microsystem and Information Technology of the Chinese Academy of Sciences, said in an interview with the media that in terms of the impact of electromagnetic microwave radiation on the activity of biological cells, mobile phones are tens of millions times more than other radiation. When you put your mobile phone to your ear to make a call, the microwave will enter the brain. Different parts of the brain react differently to microwave radiation. The eyeball is most likely to absorb radiation, and its heat dissipation function is poor. Once too much heat is accumulated, it is very easy to cause cataracts and other symptoms.
??
?? Researchers at the Israel Institute of Technology have conducted a study and found that if male calves with a similar structure to human eyes are exposed to microwave radiation from mobile phones, the focusing ability of their eye lenses will weaken after two weeks; after stopping exposure, the lens damage will gradually recover. But the foam formed inside the lens will not disappear. Researchers said that this is like "the foam formed after boiling water." In August this year, the research team released a report saying that long-term exposure to microwave radiation from mobile phones will cause cataracts and other signs in eye tissues. Professor Li said that apart from patients with severe illness, microwave radiation from mobile phones can cause neurasthenia, palpitations, chest tightness, dizziness, lack of energy and other symptoms, and there are countless such cases.
Recently , media reported that China's first "Electromagnetic Radiation Exposure Limits and Measurement Methods" (draft) will be issued before the end of this year, and there will be clear regulations on mobile phone radiation. Professor Li suggested that in order to avoid mobile phone radiation, do not rush to bring the phone close to the ear when dialing; try to use headphones to answer calls; reduce the frequency of mobile phone use as much as possible; do not put the phone in the chest pocket or hang it around the waist

?? Recently, there is a saying among the public: when the signal strength of a mobile phone is only one bar, its emission strength is more than 1,000 times different from that when it is full, so people who often use mobile phones must pay attention. This news has been widely spread through the Internet, making the radiation problem of mobile phones the focus of public attention again.
??
?? The reason why mobile phones can make calls anytime and anywhere is that they are always in contact with base stations. Therefore, as long as they are turned on, mobile phones will continue to emit electromagnetic radiation waves. Studies have shown that once electromagnetic wave radiation exceeds the limit, it can cause more serious symptoms of neurasthenia in the human body, and even cause damage to or death of internal tissues in severe cases. Moreover, the greater the radiation power and the closer the distance, the greater the damage to the human body.
??
?? There is no conclusion on whether mobile phones are harmful
??
?? Research on the harm of mobile phone radiation to the human body has not stopped in recent years. Research by Professor Zhang Yuanzhen of Zhongnan Hospital of Wuhan University shows that mobile phone electromagnetic radiation can cause damage to testicular germ cells. Professor Liu Weiguo of the Department of Neurosurgery at the Second Affiliated Hospital of Zhejiang University School of Medicine pointed out that microwave radiation from mobile phones has a certain damaging effect on the central nervous system, which is more obvious for people with skull defects.
??
?? Researcher Wei Kedao of the Institute of Radiation Protection and Nuclear Safety Medicine of the Chinese Center for Disease Control and Prevention told reporters that the question of whether mobile phone radiation will cause harm to the human body has not yet been determined in the industry, because most of the experimental results are obtained from animals, and it is still unknown how much impact it has on the human body. However, as an ordinary consumer, it is best to hold the mentality of "it is better to believe it than not to believe it", try to use mobile phones less and use landlines more.
??
?? Try to use mobile phones less
??
?? Experts pointed out that the intensity of mobile phone radiation is related to the production technology of mobile phone manufacturers. Mobile phones of different standards, brands and models have different radiation intensities. Moreover, the radiation emitted by mobile phones is different when they are in different states. The radiation from a mobile phone will suddenly increase when it is connected. When the mobile phone signal is just connected, the signal transmission system is not stable and is at the maximum operating frequency, which is also the time when the radiation is strongest. After that, the radiation from the mobile phone will decrease rapidly and remain in a stable state, so the mobile phone should be kept away from the head when it is connected. The radiation intensity of outgoing calls greatly exceeds the radiation intensity of incoming calls, so you should make as few calls as possible.
??
?? In response to this popular news recently, researcher Wei Kedao pointed out that when the signal is not good, the radiation will indeed increase. At this time, the antenna should be pulled out to improve the call quality and reduce radiation. You can also try to use separate headphones to reduce the contact between the phone and the body. However, there is no research to confirm whether the emission intensity will differ by more than 1,000 times compared to when it is full.

?? Mobile phones have become an essential communication tool for people in today's society. From teenagers to the elderly, the number of people using mobile phones is increasing. However, Li Anmin, director of the Department of Neurosurgery at the First Affiliated Hospital of the PLA General Hospital, pointed out that the high-frequency electromagnetic radiation emitted by mobile phones during calls can cause varying degrees of harm to the human body if used for a long time or excessively. At present, there are many severe cases caused by mobile phone radiation abroad, but few have been found in China, mainly because they are not aware of this problem. Even if there are similar patients, most hospitals will not think that it is a problem of mobile phone radiation.
??
?? "Whether mobile phone radiation is harmful to the human body has caused a lot of debate, but as a scientific worker, I can say with certainty that it is harmful." Director Li Anmin said that scientists from all over the world have now proved through various experiments that mobile phone radiation is harmful to the human body. British scientists used electromagnetic fields at the frequency of mobile phones to irradiate nematodes and found that the nematode protein produced an effect similar to thermal shock, just like being slightly boiled. If the radiation is stopped at this time, the nematode protein can still return to normal. If the radiation continues, the protein will undergo irreversible denaturation. The University of Essen in Germany compared 593 patients with retinal melanoma and found that the incidence rate of those who frequently used mobile phones was three times that of those who rarely used mobile phones. This is because the head is the main area of mobile phone radiation, and the retina is a fragile nerve tissue. The British Ministry of Education also prohibits students under the age of 16 from using mobile phones, on the grounds that the nervous system of adolescents has not yet fully developed, the head is small, the skull is thin, and the intensity of ionizing radiation is high, making them more vulnerable to damage.
Director
Li Anmin said that the widespread use of mobile phones has made us covered in "electronic fog" and there is nowhere to hide, and this electromagnetic radiation affects our bodies all the time. When we use mobile phones to make calls, the phone converts the audio signal into high-frequency oscillating microwaves through the converter, and then transmits it in the form of electromagnetic waves through the antenna. At this time, relatively strong electromagnetic radiation will be generated near the phone. Even if we don't make calls, it is difficult to avoid being affected by radiation. A mobile phone is equivalent to a small microwave transmitter, and the damage to the human body caused by microwaves is thermal damage. Many people have this experience. After using the mobile phone for more than a few minutes, the ears and face will feel hot. Mobile phone radiation is particularly harmful to the brain and eyes, which are tissues with high water content. The highest water content of the brain and eyes in the whole body reaches 75%. In addition, the frequency of mobile phone radiation is between 890 and 900 MHz, and the radiation energy is relatively large. It will produce high-frequency vibrations on brain cells, which may affect the normal work of cells at the least, or cause degeneration and necrosis of brain cells at the worst. To be precise, some brain cells are like being "scalded". Long-term use of mobile phones will definitely affect the function of the brain, causing memory loss, insomnia, and even mood changes. Some people may also develop malignant brain tumors due to the deformation of nerve cells and glial cells. In addition, the eyeball is more likely to absorb electromagnetic waves, and its heat dissipation function is poor, which can easily cause diseases such as cataracts.
??
?? There is no doubt that mobile phones are harmful to the human body, but we should not worry too much. The human body has an active immune system that is responsible for immune regulation, immune monitoring, immune killing and immune repair. Whether it is ionizing radiation or non-ionizing radiation that causes damage to the molecular structure of cells, it will be accurately identified and precisely repaired by a healthy immune system to maintain the integrity of the functions of human cells and organs. In layman's terms, the human immune system will "eat" the degenerated cells after discovering them, and this process is ongoing all the time. However, due to the decline of the immune system, a large dose of ionizing radiation or long-term low-dose radiation, all of which exceed the monitoring and repair capabilities of the human immune system, human cells finally undergo irreversible deformation, and the deformed cells proliferate disorderly, and malignant tumors are generated.
Director
Li Anmin emphasized that everything has a process from quantitative change to qualitative change, and the damage caused by mobile phone radiation to the human body is not exactly the same due to individual differences. However, some bad eating habits and living habits can induce malignant tumors, and the same is true for electromagnetic radiation. Therefore, reducing the "electronic fog" surrounding the human body is definitely beneficial to health, so it is better to be careful about mobile phones. When using a mobile phone, do not put it close to your ear when dialing. Put it close to your ear after the call is connected, so as to reduce the high-intensity electromagnetic radiation generated by the mobile phone when it is transmitting. Reduce the frequency of using the mobile phone as much as possible. If there is a landline, try to use it. It is best to use a special mobile phone headset with a shielded cable. Try not to put the mobile phone in your chest pocket or hang it around your waist. Keep a good mental state and pay attention to the combination of work and rest. These effective measures can play a key role in preventing the damage caused by mobile phones to the brain.

　　Radiation is fiercer than a tiger. Should you be on guard or not?

　　Do you often use your mobile phone in the subway, light rail or bus?

　　Be careful. "Office workers will be harmed by strong electromagnetic waves from mobile phones on their way to and from work." This is a new view proposed by Takeshi Hondou, a researcher at Tohoku University in Japan.

　　Hondou's research found that the carriages of these vehicles are all made of metal, and a large number of mobile phone electromagnetic waves are reflected back and forth in the car, and the density of electromagnetic waves greatly exceeds the international safety standards. For example, if there are 50 people in each carriage, each with a mobile phone, the electromagnetic wave power of each mobile phone is 0.4 watts, and the total power in the car is 20 watts. In fact, the maximum power of each mobile phone can reach 2 watts. Added together, it will exceed the standard set by the World Health Organization by several times. What's more serious is that during rush hour, the number of passengers in each carriage will soar to 300 people. Many Japanese people often carry two mobile phones, which is even more serious.

The harm of mobile phone radiation to human health is an objective and serious social problem. It will not disappear just because the mobile phone industry deliberately conceals and avoids it.

At present, the world has begun to pay attention to the problem of mobile phone radiation and has repeatedly "deliberated" on the technical standards for radiation. Unfortunately, compared with the global popularity of mobile phones and the health of consumers, this slow "deliberation" is too late, and we have reason to believe that this procrastination will continue in many countries. Therefore, it is not the lack of technical standards for mobile phone radiation, but the lack of mechanisms to deal with this impact on public safety interests.

The era of globalization is an era in which multinational corporations dominate the global economy. The influence of large companies goes far beyond the economic scope. They have become a power system that affects the operation of society. For problems like mobile phone radiation, large companies have actually infringed on the rights of the public by avoiding industrial privacy.

Social public health should be regarded as a public product. For example, when many companies are polluting the air, the coordination and guardian of this public product should be the government.

The harm of mobile phone radiation to public health is the same. We cannot avoid the existence of radiation just because we cannot see it. Because the development of society cannot be completely equated with the development of corporate groups, but the development of the entire people. On the issue of mobile phone radiation, governments have the responsibility to accelerate the research on radiation issues and provide symmetrical radiation information to the public; they also have the responsibility to set strict standards for enterprises, so that enterprises bear more responsibilities to the public and establish a double responsibility of serving both society and profits. Therefore, mobile phone radiation is not terrible, but the terrible thing is that the international community has not established a rapid coordination mechanism to avoid the continuous occurrence of similar problems.

While modern civilization brings people a wealth of products and services, it also makes people fall into "happy troubles": with the increase in the frequency of mobile phone use, the health and safety issues caused by mobile phone radiation have become the focus of the industry.

What is mobile phone radiation ?

Studies have shown that when people use mobile phones, mobile phones will transmit radio waves to the transmitting base station, and any kind of radio waves will be more or less absorbed by the human body, thereby changing human tissues and may also have an impact on human health. These radio waves are called mobile phone radiation.

In fact, it is more reasonable to call mobile phone radiation irradiation, because the frequency used by mobile phones is between 800 and 1800MHz, which is completely different from ionizing radiation such as X-rays or gamma rays. It cannot produce ionization or radiation energy in the human body, so it is called a non-ionizing radiation field.

The international scientific community has a relatively complete set of measurement standards for the size of mobile phone radiation, which is the so-called SAR value. SAR is the abbreviation of Specific Absorption Rate, also known as the electromagnetic radiation test value. In layman's terms, it is the size of the impact of mobile phone radiation on the human body.

In 1990, the Institute of Electrical and Electronics Engineers (IEEE) formulated technical standards for measuring mobile phone electromagnetic radiation. In 1998, the International Commission on Non-Ionizing Radiation Protection (ICNIRP) also formulated similar technical standards, and the standards all use SAR to measure the size of mobile phone electromagnetic radiation.

The ICNIRP standards have been recommended by the International Telecommunication Union and the World Health Organization and supported by most countries. In China, the "Joint Working Group on the Development of National Standards for Electromagnetic Radiation" led by the General Administration of Quality Supervision, Inspection and Quarantine and jointly established with the Ministry of Health, the State Environmental Protection Administration, the Ministry of Information Industry, the State Administration of Radio, Film and Television, the State Grid Corporation and other units is jointly formulating China's electromagnetic radiation protection standards, which also use SAR as the basic limit for measuring mobile phone radiation.

Mobile phone radiation is more terrible than imagined

. With the rapid increase in the number of mobile phones, people have begun to pay more and more attention to the health and safety issues that may be caused by mobile phone radiation. However, most mobile phone users do not have a comprehensive understanding of mobile phone radiation, and more and more scientific research shows that the harm caused by mobile phone radiation is far more terrible than imagined.

Although there is still controversy in the academic community about mobile phone radiation, it is undeniable that it will cause harm to the human body under certain conditions.

A study organized by Professor Sebastian, head of the Department of Applied Physics at the Complutense University of Madrid, Spain, showed that the data obtained by the existing method obviously underestimated the impact of radiation on human tissue. Sebastian said: "Since the intensity of the electromagnetic field is greater than expected, the impact on health will be correspondingly greater. We estimate that the harm of electromagnetic radiation will continue to accumulate, and in 10 to 15 years, it is likely that more cases of illness caused by the use of mobile phones will appear."

Dr. Gunhild Ofterdell of the Norwegian University of Science and Technology and his colleagues conducted a questionnaire survey of 12,000 Swedes and 5,000 Norwegians, all of whom use mobile phones at work. As a result, 7,803 people in Sweden responded and 2,828 people in Norway responded. Among the people who participated in the survey in Norway, 31% of them had at least one symptom, while among the Swedes, 13% had one or more symptoms. The research report also showed that headaches are most likely to occur within half an hour after making a phone call, and sometimes during the call. Many Norwegians said that the pain would occur when the call lasted more than 5 minutes. Many Swedes also said that symptoms would occur when the call lasted more than 5 minutes.

In China, some researchers have also warned about mobile phone radiation. Xie Yichen, a professor of physics at Jiamusi University, believes that the current controversy about mobile phone radiation is actually just a discussion of quantity, not a question of whether it exists or not. Xie Yichen analyzed that the harm of mobile phone radiation to the human body can be understood from the well-known law of conservation of energy. Mobile phones mainly radiate microwaves outward through antennas. The essence of this radiation is the transmission of energy. These microwave energies have strong penetrating power. When they enter the human organs, according to the law of conservation of energy, they will not perish. They will transfer these energies to the human organs and convert them into other forms of energy, that is, produce thermal effects and non-thermal effects.

Xie Yichen believes that because the mobile phone antenna is close to the head when in use, the microwaves emitted are very concentrated, so long-term use of mobile phones will inevitably cause local lesions.

Treat mobile phone radiation scientifically

In recent years, researchers have been trying to find out whether mobile phone radiation affects human health, but the research results are difficult to be recognized by all scientific circles. At the same time, the research results on mobile phone radiation are not the same. In this regard, relevant Russian experts pointed out that this is caused by different research methods.

Experts from the Moscow Medical College wrote in the Russian magazine "Chemistry and Life" that there are roughly three reasons for these differences: First, many scientific research groups use different research methods, so researchers cannot compare the data obtained by these groups; second, the short observation period is another shortcoming of such research. Some lesions suspected to be related to mobile phones have a long development process, and existing methods make it difficult to determine how some early lesions are related to mobile phones; third, some research activities may be affected by investors.

Although the industry has not yet reached an accurate conclusion on how much harm mobile phone radiation brings, experts suggest that it is best not to wait until the harmfulness of mobile phone radiation is fully confirmed before taking preventive measures. Stewart, chairman of the National Radiation Protection Safety Committee of the United Kingdom, once warned that regarding mobile phone technology, our committee is very concerned about its impact on public health. Although mobile phones have become a part of daily life and even a fashionable decoration for some people, it cannot be said that they are safe just because people use them. Ms. Marin, the head of the German Consumers Association, believes that the most important thing at present is to give consumers a control standard for mobile phone radiation.

Mobile phones are a new type of communication tool commonly used in modern people's lives and work. With the development of science and technology and the improvement of living standards, the status of mobile phones is becoming more and more important, and their popularity is becoming more and more widespread. Therefore, countries around the world pay special attention to the increasingly serious mobile phone radiation, and have formulated relevant laws and regulations to manage the mobile phone radiation environment. Scientists and researchers in various countries are also actively exploring the harm caused by mobile phones to human health and are taking corresponding measures to eliminate this impact. Take Germany as an example. As early as July 2001, the German Minister of the Environment stated that the German government will strengthen the management of radiation generated by mobile communications and require that starting from the autumn of that year, mobile phone manufacturers must accurately indicate the radiation level in the mobile phone manual.

Some mobile phone manufacturers are also very concerned about the issue of mobile phone radiation. Ning Shuyong, public relations director of Sony Ericsson China, said that as a representative of high-end mobile phones, Sony Ericsson's mobile phone products have always implemented strict mobile phone radiation standards. All Sony Ericsson mobile phone products have radiation values marked in their manuals and product websites. In addition, Ning Shuyong also revealed that Sony Ericsson has extracted a green substance from some vegetables for mobile phone manufacturing, which is currently being tested. Haier, which has always been good at solving user problems, has once again brought surprises to everyone. It is understood that some models of Haier mobile phones have successfully passed the mobile phone SAR value test of the Certification Center (CEC) of the State Environmental Protection Administration, and the first batch has obtained the Type II Environmental Label Certification, which effectively reduces the radiation value and protects the health of consumers.

Of course, many products are potentially dangerous to people. Questions such as whether mobile phone radiation will affect human health are not abrupt in the context of high technology rapidly changing human lifestyles. The key to the problem is to solve technical problems with a scientific attitude, which should be the rational thinking of human beings to correctly treat mobile phone radiation. In other words, humans should neither abandon civilization because of possible harm, nor simply ignore it; instead, they should pay appropriate attention to each process including research and development, use, and management.

　 Scientists have not given a clear answer to whether mobile phones are harmful or not. The latest research by EU scientists confirms that mobile phone radiation can damage cells and DNA that records human genetic information.

　　Most brand mobile phones have too strong radiation .

　　This world's largest mobile phone radiation survey and research, titled "The Effect of Electromagnetic Fields on Human Cells", was completed by 12 research teams from seven EU countries over a period of three years. Experts found that if the radiation from a mobile phone to each kilogram of human tissue is greater than 1.3 watts, it will damage human DNA, but the radiation limit value generally stipulated now is 2 watts per kilogram. Tests show that many brands of mobile phones have radiation exceeding 1.3 watts.

　　In addition, the German research team also found the impact of mobile phones on blood genes. They said that electromagnetic fields can cause the human body to produce a harmful protein, which causes changes in the genes of human blood cells. The Swedish research team also found that mobile phone radiation can cause protein deposition and may induce Alzheimer's disease. British experts also warned that mobile phones may release toxic mercury gas, induce multiple sclerosis, harm fertility, and cause premature aging and memory loss.

　　Whether it damages organs is still undecided

　　. However, although experts believe that mobile phones can damage DNA, when it comes to specific health hazards, they use words such as "may". Dr. Fitzner of the Teaching Hospital of Humboldt University of Berlin said: "We have not found strong evidence whether mobile phone radiation can cause damage to human organs."

　　Although there is insufficient evidence that mobile phones damage human organs, many European biologists, medical scientists and environmental experts advise people to use mobile phones with caution. They believe that in order to realize the communication function, mobile phones must be in uninterrupted contact with the transmitting base station, which will inevitably receive and send strong communication waves, so it will definitely have a negative impact on the human body. Professor Rudiger from Vienna suggested: "It is best to use mobile phones less; if you have to use them, go outside or by the window to make calls, or use headphones." Germany's "Health" magazine believes that wrapping a layer of ceramic or metal shell on the outside of the mobile phone's headphone cable may help reduce mobile phone radiation.

　　The study has attracted the attention of the WHO.

　　Regarding this survey result, major mobile phone manufacturers claim that their products are very safe. Ms. Marin, the head of the German Consumer Association, believes that the most important thing now is to give consumers a control standard for mobile phone radiation. Now, many European consumers believe that mobile phone radiation is harmful to the body, because up to now, no company has dared to deny the connection between mobile phones and health.

　　It is reported that this investigation has attracted the attention of the World Health Organization (WHO), which said that they will release an authoritative mobile phone radiation report within 3-4 years. By then, there will be a clear and authoritative statement on the relationship between mobile phone radiation and health.

?? Research in the international medical community has shown that mobile phone radiation can cause neurasthenia, memory loss, decreased appetite, palpitations, chest tightness, dizziness, insomnia, dreaminess, and even lack of energy and decreased libido. The "Jinyi" brand mobile phone electromagnetic wave eliminator is developed based on the stealth technology of military cutting-edge technology (stealth aircraft, stealth ships, etc. absorb electromagnetic waves emitted by radar by coating the body with absorbing materials to achieve the purpose of stealth). It is a special product used to eliminate the harm of mobile phone electromagnetic wave radiation to the human body.

?? As early as July 17, 1999, the "Guangzhou Daily" made a report entitled "Hanging a mobile phone around the waist can hurt the liver, kidneys and ovaries". On October 15 of the same year, the "Yangcheng Evening News" made a report entitled "Mobile phone microwaves may help toxins enter the brain", which made the most systematic explanation and reminder of the harm of mobile phone radiation to the human body. However, the media's kind reminders less than 3 months apart did not attract the attention of consumers and mobile phone users. On May 20, 2005, the Global Times published a report titled "Using mobile phones in the suburbs makes you more likely to get a brain tumor." It was nearly six years after the first domestic media reported that mobile phone radiation was harmful to the human body. People finally paid attention to this matter and were touched. During this period, major media across the country made more than 30 similar interviews or news reports, including authoritative reports from famous newspapers such as People's Daily, Guangming Daily, and China Youth Daily, as well as CCTV-2's "Ma Bin Reading Newspaper" column. With the reports of many news media, people began to understand this fact. Through the in-depth and detailed explanations and excavations of the media, mobile phone owners have awakened.
??
?? In China, with the rapid popularization of mobile phones and the continuous improvement of people's health awareness, the harm and protection of mobile phone microwave radiation have evolved from the skeptical discussion of the year to the demonstration of the harm mechanism, and then from the confirmation of the harm results to the strengthening of protection awareness today. This topic, which has become recognized and concerned by countries around the world, has finally been clearly concluded. This long process, which lasted for several years, is also the process that mobile phone manufacturers have gone through in their attitude towards the fact that mobile phone radiation is harmful to human health, from being tough-acknowledged-lamented. The harm of mobile phone radiation has become an indisputable fact. Professor Li Anmin, a neurosurgeon at the 304th Hospital of the Chinese People's Liberation Army,
once
pointed out that the electromagnetic waves radiated by mobile phones have a strong carcinogenic effect on human cells and can cause cell cancer. He also confirmed that rare brain tumors are related to using mobile phones. Professor Zhao Yufeng, director of the Electromagnetic Protection Research Laboratory of the Beijing Institute of Labor Protection Science and an expert in radiation protection, once said that the statement that mobile phone radiation is harmful to human health has been concluded in various countries around the world. The only difference is under what circumstances and to what extent it harms human health.
If
you still have doubts about the harm of mobile phone radiation to health at this time, or you are half-believing and half-doubting, let us analyze the mechanism of action of mobile phone radiation on the human body from a theoretical perspective.
??
?? Anyone who has studied physics knows that mobile phone radiation is a kind of energy. According to the "law of conservation of energy", this energy can neither be generated nor disappear out of thin air. It can only be converted from one form to another and transferred from one object to another. However, the total amount of energy will not change. Therefore, when using a mobile phone, since microwaves have a strong penetrating ability, the mobile phone will transfer this energy to organs or tissues such as the brain, eyes, and skin of the human body. In particular, these more fragile organs or tissues of the human body are its favorite objects. At the same time, this microwave energy will be converted into two forms of heat energy and non-thermal energy through these substances, which will cause damage to human cells. If we say heat energy, it will not be difficult for us to understand. Everyone should be very familiar and clear about the heating effect of microwaves.
??
?? In life, most families use
a
microwave oven. Usually, a microwave oven can "cook" raw meat in a very short time. This is the best and most realistic example of energy conversion. When we answer or make a phone call, our ears often get hot. This is the effect of microwave heating. Of course, the power emitted by mobile phones is far less than that of appliances such as microwave ovens. However, data tests show that the microwave radiation of mobile phones can raise the temperature of the body's water-rich parts to 42-44 degrees Celsius. Therefore, repeated use of mobile phones and repeated heating of local organs or tissues by microwave energy will activate the heat shock protein in the human body, which will destroy the defense system of human cells and hinder the human immune system from repairing and cleaning damaged cells for recovery, thereby causing more and more harmful cells and damaged cells, and continuously increasing the probability of cell canceration, and the possibility of corresponding organs or tissues in the human body becoming cancerous will increase.
??
?? Research in the international medical community has shown that mobile phone radiation can cause neurasthenia, memory loss, decreased appetite, palpitations, chest tightness, dizziness, insomnia, dreaminess, and even lack of energy and decreased libido. The famous Swedish brain tumor expert Hadel pointed out through a study of 1,617 brain tumor patients that the probability of long-term use of mobile phones to develop brain tumors is much higher than that of people who do not use mobile phones. The probability of people who use mobile phones for more than 10 years to develop brain tumors is as high as 80%. The British Sunday Times reported that mobile phone radiation may cause eye cancer, which has once again attracted strong attention. A study by German scientist Dr. Andres on 593 eye cancer patients showed that people who often use mobile phones are three times more likely to develop eye cancer than those who use them less frequently. Cytologist Frenzo Marinelli of the Italian National Institute and his team confirmed that mobile phone radiation can easily induce leukemia, which is probably due to the damage of mobile phone radiation to DNA. Mobile phones are often placed next to the waist and abdomen of the human body. Mobile phone radiation can cause unbearable damage to sperm and eggs. It can affect women's endocrine system, endanger reproductive function, and may cause fetal malformation. This is what experts have pointed out that the use of mobile phones can easily cause infertility in men and women. Scientists and the medical community generally believe that mobile phone radiation can cause greater harm to minors under the age of 18, because their immune systems are not particularly sound and their brains are not yet mature, so they are more vulnerable. Experts also pointed out that due to the heating effect of mobile phone radiation, microwaves will repeatedly heat the skin of the ears, face and neck during mobile phone calls. Over time, it will cause the skin in these parts to become dry, thereby causing the facial skin to age prematurely.
??
?? It should be noted that Professor Zhao Yufeng, an expert in radiation protection, said that according to the understanding and test results of professional departments, most mobile phone microwave radiation exceeds the standard, generally several to dozens of times, and the highest can reach 200 times. Because China's mobile phone radiation detection standard uses the mobile phone's transmission power as the evaluation indicator, while in Europe and the United States, their detection standards use the unit absorption rate (SAR) of the electromagnetic wave of the mobile phone radiation acting on the human body as the evaluation indicator. Based on this standard, the harm of mobile phones to the human body may be far greater than we imagine, so our mobile phone users should have more self-protection awareness and it is very wise to take more protective measures. At the same time, radiation protection technologies and products studied and used by scientists from various countries have also emerged.
??
?? Faced with such a grim reality, Beijing Huashiming Technology Development Co., Ltd. resolutely took on the great mission of protecting the health of mobile phone users and was the first to walk in the forefront of this field. Beijing Huashiming Technology Development Co., Ltd. is a Sino-Korean joint venture high-tech enterprise dedicated to professionally removing mobile phone electromagnetic wave radiation that is harmful to the human body. The Korean listed company, Shiming Electric Industry Co., Ltd., is one of its major shareholders. At present, the company's main product, the "Jinyi" brand mobile phone electromagnetic wave eliminator, has won the gold medal of the French International Invention Exhibition, the Korean national patent (patent number 0257950), the Chinese national patent (application number 200410086840.), the German CE quality certification, the Republic of Korea Q quality certification, ISO9000 quality certification, the Korean Environmental Industry Award, the Korean Electronic Accessories Award, the China Quality Association Quality Reputation Query Product, and the "Beijing Red Cross Health Care Service Center Designated Product", "China Quality Wanlixing Director and Strategic Alliance Unit", "China Smart Engineering Research Institute Director" and "China Entrepreneur Health Project 2005 Annual Meeting Designated Special Product" and other honorary titles.

?? The radiation absorption rate of the Ministry of Information Industry is as high as 99%.
??
?? The "Jinyi" brand mobile phone electromagnetic wave eliminator is developed based on the stealth technology of military cutting-edge technology (stealth aircraft, stealth ships, etc. absorb the electromagnetic waves emitted by radar by adding absorbing materials on the body to achieve the purpose of stealth). It is a special product used to eliminate the harm of mobile phone electromagnetic wave radiation to the human body. The absorbing material in its product can effectively absorb the harmful electromagnetic wave radiation generated by the mobile phone, reduce the incidence of brain tumors caused by mobile phone electromagnetic wave radiation, slow down the increase of facial skin wrinkles and premature aging caused by mobile phone electromagnetic wave radiation, and eliminate the symptoms of ear heat, dizziness, head swelling, lack of sleep, neurasthenia, cell damage, etc. It is a special product that achieves protection function by weakening the excess electromagnetic waves in the antenna part of the mobile phone and eliminating the invalid electromagnetic waves in the handset and microphone. When the mobile phone is talking, the whole body is emitting radiation to the outside, of which there are three main radiation sources: antenna (the emitted radiation is used for talking), handset and microphone (useless radiation is generated because of the coil). The radiation from the earpiece and microphone (that is, useless radiation that does not affect the call) will directly harm the human brain through the ear canal, and at the same time affect the facial skin, making people who often use mobile phones have a greatly increased chance of brain tumors and facial wrinkles. Stick this product near the earpiece and microphone of the mobile phone, and the useless radiation will be absorbed by the wave-absorbing and radiation-proof materials in the product, so as to achieve the purpose of not affecting the call quality and protecting the radiation hazards of the mobile phone.
??
?? The "Jinyi" brand mobile phone electromagnetic wave eliminator has been identified by the National Nonferrous Metals and Electronic Materials Analysis and Testing Center as follows: the metal interlayer in the middle of the film is gold, with a purity of 99.8%. Therefore, this product is not only a high-tech radiation protection product, but also can be collected as a collection and given as a gift to others, integrating practicality, preciousness and fashion. A social survey conducted by a Korean TV station at the end of 2004 showed that the proportion of Korean mobile phone users who have used "Jinyi" products is as high as 60%, and it is still rising. This fully shows that the "Jinyi" brand mobile phone electromagnetic wave eliminator is in line with market demand.
??
?? At the end of 2004, Beijing Huashiming Technology Development Co., Ltd. (a Sino-Korean joint venture) invested heavily and brought this product to China with the purpose of "everything for consumer service, everything for dealers' profits". It also made huge profit margins in China's 420 million mobile phone market, and created 300 dealers in China with annual income of more than 1 million yuan with the advantages of successful terminal sales model, perfect after-sales service system and free training mechanism, reasonable terminal consumer price, leading technology quality, strong advertising support, Korean original mature products and brands, four authoritative certifications, and three authoritative awards, so that this great radiation protection health product can quickly benefit China's 420 million mobile phone users and fully serve China's health and environmental protection cause.
