The harm of electromagnetic radiation inside cars is exaggerated
Radiation source: wherever there is electricity, there is radiation
Electromagnetic radiation is a substance that exists in a special form that is invisible and intangible. The Earth, where humans live, is itself a large magnetic field, and its surface thermal radiation and lightning can generate electromagnetic radiation. The sun and other planets also continuously generate electromagnetic radiation from outer space. The natural magnetic fields, sunlight, household appliances, high-voltage transmission lines, etc. surrounding humans are emitting electromagnetic wave radiation of varying intensities, and wherever there is electricity, there is radiation.
Cars, due to the increasing use of electronic devices, inevitably bring radiation sources, but compared to others, they are still relatively safe. Xu Jie also stated that in car navigation, radio and other equipment may generate radiation. In daily life, the source of radiation is more often mentioned in household appliances, and the radiation of a car is even far less than the commonly used small mobile phones. The study by the World Health Organization shows that the electromagnetic radiation emitted by a mobile phone is the highest when connected. Therefore, it is best to hold the phone far away, wait for it to be connected, and then bring it closer to listen, or wear radiation resistant headphones to answer calls.
Absence: No relevant national standards
Since the 1990s, China has been adopting the recommended limit of 0.1mT for power frequency electromagnetic radiation in the public environment by the International Radiation Protection Association. In sharp contrast to this, there are stricter standards in other countries - the official website of the UK National Radiation Protection Commission sets the hazard value at 0.4 μ T (4mG), and it is internationally recognized that the magnetic field intensity in children's living environments should not exceed this standard; Sweden is the first country to believe that electromagnetic radiation intensity above 0.2 μ T (2mG) is harmful to human health.
The International Committee on Non ionizing Radiation Protection (ICNIRP) stipulates that "it is safe for residents to be exposed to within 1.00mG milligauss within a range of 2 meters from electrical appliances."
Experts also indicate that in fact, there is no universally recognized standard in the country, so it is generally difficult for the public to grasp. A staff member from a complete vehicle factory revealed to the captain that there is currently no mandatory standard for electromagnetic radiation in the automotive industry, and most car companies do not specifically test the radiation of electrical equipment inside the car on the human body when producing cars.
