Recently, the topic of radiation inside the car on Weibo has been heatedly raging. There has been no stalemate between the two sides, but there has been no result in the struggle to win the battle. Everyone has misunderstood and misgivings to say that they are holding different standards. Less than one went, the winds and horses were unmatched, and the ordinary people became confused and confused.

Carefully scrutiny of this matter, we can find that the crux of this controversy is: With regard to interior radiation, there is no national mandatory standards. In other words, we do not know what to determine if the radiation has exceeded the standard? Can only judge by feeling. There is no credibility in nature.

There is also a point of view that the radiation in the car is not worth mentioning and will not cause any harm to human health at all. This view is sent by some so-called experts. It may have a certain degree of rationality and is the conclusion of decades of experience. I would rather believe this point of view is correct, but after all, there is uncertainty in the experience, just as there is no direct evidence to prove that there is no relationship between the use of mobile phones and brain tumors, but no one can say clearly why the use of mobile phones is more, The higher the incidence of brain tumors.

Of course, we also believe that there will be no radiation and no lethality in that point in the car. Of course, it is not as good as a microwave oven or induction cooker. But after all, the qualifier is in the car. We have a small space. We are indeed paralyzed. Well, eliminate our concerns and come up with standards. However, after a round of inspection, there was no standard in this respect. A circle was asked. The manufacturer did not do this test during production.

We only have a limit on the frequency of electromagnetic radiation in the public environment. Since the 1990s, China has adopted the 0.1mT limit recommended by the International Radiation Protection Association, but it is more stringent in other countries – the UK National Radiation Protection Commission's official website puts The value is set at 0.4μT (4mG), while Sweden believes that electromagnetic radiation intensity above 0.2μT (2mG) will be harmful to the human body.

Looking at the comparison of electromagnetic radiation in various countries, we initially came to a conclusion that our standards are lower than those of other countries and that standards were established 20 years ago and have not been revised. However, we still do not see the radiation standards in the car. People in the industry also said that there is currently no mandatory standard for electromagnetic radiation in the car industry. Generally, car manufacturers will not specialize in the production of automobiles. The electrical equipment in the vehicle detects the radiation of the human body. We did not see the official out of authoritative conclusions, explained why there was no standard, and even why it was not necessary to establish standards for this purpose. Even if you tell us, the radiation in the car does not need to be considered at all. In the case of asymmetric information, many small issues will be amplified. Consumers are not experts. We will be uneasy, standards will be missing, and consumers will be assured.
