So far, no research shows that there is consistent evidence that exposure to radio frequency field intensity below the limit value that causes tissue fever will have adverse health consequences. In the statement of 20 18, the US Food and Drug Administration (fda) pointed out that at present, the radio frequency energy of mobile phones is still within the safety limit, which has little impact on public health. The Environmental Protection Agency (epa) and the National Toxicology Program (ntp) of the United States have not officially listed radio frequency radiation as a carcinogen. It is also mentioned that the energy of radio frequency radiation can only slightly move or vibrate atoms in molecules, but it is not enough to ionize them, which is much safer than high-energy radiation such as X-rays and gamma rays. This proves that radio frequency radiation will not cause cancer by destroying dna.
The International Agency for Research on Cancer (IARC) is a professional organization under the World Health Organization. At the end of 20 1 1, it lists the radiation from mobile phones as a substance that may cause human cancer (category 2b). "Class 2b" substances are considered to be "possibly carcinogenic to human body". However, the evidence of carcinogenicity of these substances in animal experiments is not sufficient, and the evidence of carcinogenicity to human body is limited. Category 2b also includes possible carcinogens such as kimchi, saccharin and coffee. Therefore, the "possible carcinogenicity" defined by WHO has more taxonomic significance.
The study of current standards shows that there is still no need to worry too much about millimeter waves. Scientific experiments show that 60ghz millimeter wave radiation of 10 MW/cm2 will not cause harm to eyes for 8 hours. At the same time, skin experiments under similar conditions show that it will not cause harm to human body.
