Is 5G millimeter wave (mmWave) harmful to human body?

Consumers have been worried about whether radio frequency radiation will increase the risk of cancer. To answer this question, we contacted the Food and Drug Association of the United States (FDA), a government agency responsible not only for food and drug control and supervision to protect public health, but also for electromagnetic radiation launchers.
What is radiofrequency radiation?
First, let's define radiofrequency radiation. Actually, the word radiation is not as frightening as it sounds. Radiation is the release of energy, that is to say, the heat from our body is also counted as radiation.
RF radiation is another name for radio waves. As the FDA said, radio frequency radiation is a form of electromagnetic wave, which consists of electromagnetic wave and magnetic energy radiated in space.
Is radiofrequency radiation safe?
The radiation emitted by mobile phones belongs to low-energy radiation of electromagnetic spectrum, which is much safer than high-energy radiation such as X-ray and gamma-ray. High-energy radiation mainly releases ionizing radiation, which means that they have enough energy to ionize atoms or molecules, thus destroying cell DNA, which may lead to cancer, while radiofrequency radiation does not. Radiofrequency radiation can only move or vibrate atoms in molecules slightly, not ionize them. Although this only means that radiofrequency radiation cannot cause cancer by destroying DNA cells, the effect of non-ionizing radiation remains to be studied.
In a statement in 2018, the FDA pointed out that the radio frequency energy of mobile phones is still within the safety limits and has little impact on public health. The United States Environmental Protection Agency (EPA) and the National Toxicology Program (NTP) have not officially classified radiofrequency radiation as a carcinogen. But on the other hand, the World Health Organization's International Agency for Cancer Research (IARC) classifies radio frequency radiation as "potentially carcinogenic" because a study has found a possible link between cell phone use and certain types of brain tumors. However, according to the International Agency for Research on Cancer, the evidence is limited and the International Agency for Research on Cancer has previously classified coffee and talc powder as "potentially carcinogenic".
In a recent study conducted by the National Toxicology Program (NTP), high exposure to radiofrequency radiation of 2G and 3G increased the risk of cardiac tumors in male rats. However, John Butcher, a senior NTP scientist, pointed out that the level and duration of radio frequency radiation in the experiment were much higher than the highest level of people using mobile phones, so the results could not be directly concluded. In addition, John Butcher adds that 5G may be very different from 2G and 3G, so further research is necessary.
Is 5G technology dangerous to human health?
The FDA said it still believed that the radio frequency energy of mobile phones was still within safety limits and had little impact on public health. A spokesman for the agency wrote in an e-mail, "Restrictions are based on the frequency of equipment. 5G has different standards than other technologies. We are committed to protecting public health. The FDA will continue to review and rely on relevant scientific and medical evidence to explore the effects of radiation on human health." The FDA also pointed out that they listed some important ongoing research on the subject of radio frequency on their website.
So is 5G millimeter wave safe?
According to the opinions of experts and current research, there is no evidence that 5G millimeter wave poses a serious threat to human health, but we can not conclude on this issue, and more research needs to be done. If you still don’t feel reassured, you can also pay attention to scientifically using your smartphones in your daily life, such as putting your cell phone away from your bed when you sleep at night. However, according to current studies, the cancer risk level of radio frequency radiation belongs to the category of "possible carcinogens" from the International Agency for Research on Cancer, which means that the risk of disease is the same as that of coffee you drink in the morning.
