All the "hazards" of electromagnetic radiation from electric vehicles are here!

"Putting your phone on the bedside will affect your memory", "Be sure to turn off WiFi when you go to bed at night", "Put a cactus next to your computer to prevent radiation", I believe you have heard this kind of words more or less in your life. In recent years, with the promotion of new energy vehicles, the issue of "radiation from electric vehicles" has become a hurdle that many people cannot get over. Coupled with the analysis and tests of various bloggers and media on the Internet, it is even more ambiguous. I don't read much, don't lie to me! For new things, everyone will have a natural defensive psychology, which is normal, especially when everyone pays more and more attention to health. But what is the fact that "electric vehicles have radiation"?

First of all, what is radiation?

Let's open Baidu Encyclopedia to learn about it first - radiation refers to the phenomenon that an object emits energy into the surrounding space. In other words, everything in the world has radiation, including the human body, food, and everything around us (anything in the universe with a temperature higher than -273.15℃ has radiation).

Since our human body has radiation, there must be harmless and harmful radiation. Radiation is divided into ionizing radiation and electromagnetic radiation. Ionizing radiation means that the energy of the radiation itself is extremely high, so high that it can ionize the surrounding matter (in simple terms, ionizing radiation can destroy the stability of atoms and chemical bonds). In daily life, hospital X-rays, CT, gamma knives for cancer treatment, proton heavy ions, nuclear radiation, etc. are all ionizing radiation (PS: B-ultrasound and nuclear magnetic resonance are both "radiation-free" examination methods). Another type of non-ionizing radiation, also known as electromagnetic radiation, has a low frequency and no basis for causing disease. Instead, it serves many technologies that are indispensable to modern life. Common microwave ovens, mobile phones, Wifi and mobile phone signals in life, as well as the protagonist of this article - electric cars, all belong to this category. So are electric cars harmful to the human body?

As an industrial product, cars must undergo various rigorous tests during production. Whether it is a regular fuel car, a hybrid car or a pure electric car, the amount of electromagnetic radiation to the human body needs to be tested. There are even stricter testing standards for electromagnetic compatibility testing internationally.

According to the United Nations World Health Organization's safety standards for electromagnetic radiation and electromagnetic fields, the safety standard for electric field radiation is 5000V/m, and the safety standard for magnetic field radiation is 100μT. In other words, as long as ordinary household appliances are lower than 5000V/m and 100μT, their radiation values ​​are within the safe range. Taking electric vehicles as an example, the driver's seat radiation is 0.88μT, the co-driver's is 0.85μT, and the back seats from left to right are 0.47μT, 0.43μT and 0.39μT respectively. Overall, the electric field radiation of various parts of the car is less than 5V/m, and the magnetic field radiation is less than 1μT, which is much lower than the electromagnetic radiation of daily technological equipment such as mobile phones and laptops.

Are you still worried about the radiation of electric vehicles after seeing this? In daily life, there is no need for everyone to be in danger, because both the electronic products and electric vehicles we use have been professionally tested before entering the market. In fact, rather than being vigilant about the electromagnetic radiation of electric vehicles, we should pay more attention to driving safety.
