What harm does radiation do to human body? Pray for the great gods.

According to experts, electromagnetic radiation has six main effects on human body. One of the hazards is that it is probably one of the causes of childhood leukemia. Medical research has proved that long-term exposure to high electromagnetic radiation will change blood, lymph and cell protoplasm. The second hazard can induce cancer and accelerate the proliferation of cancer cells in the human body. Electromagnetic radiation pollution will affect the circulatory system, immunity, reproduction and metabolic functions of human body, and even induce cancer in severe cases, accelerating the proliferation of cancer cells in human body. The third harm affects the human reproductive system, mainly manifested in the decline of male sperm quality, spontaneous abortion of pregnant women and fetal malformation. The fourth hazard will lead to children's intellectual disability. Some experts believe that electromagnetic radiation is also one of the influencing factors. The World Health Organization believes that the electromagnetic radiation from computers, televisions and mobile phones has a negative impact on the fetus. The fifth hazard affects people's cardiovascular system, which is manifested as palpitation, insomnia, menstrual disorder in some women, bradycardia, decreased cardiac blood volume, irregular sinus heart rate, leukopenia and decreased immune function. The sixth hazard has a bad influence on people's visual system. Because eyes belong to the sensitive organs of human body to electromagnetic radiation, too high electromagnetic radiation pollution will cause vision loss, cataracts and so on. High-dose electromagnetic radiation will also affect and destroy the original biological current and biological magnetic field of human body, making the original electromagnetic field of human body abnormal. It is worth noting that different people or the same person have different tolerance to electromagnetic radiation at different ages, and the elderly, children and pregnant women are sensitive to electromagnetic radiation. As for whether there is electromagnetic radiation after turning off the TV or computer, it is like this: after turning off the TV or computer for a period of time, there is definitely no radiation, but if it is just turned off, the display will still have some radiation in a short time, because there are high-voltage bags and electron guns that shine on the screen, and there will still be residual electricity in a short time, so there will still be radiation in a few minutes. I hope to attract attention. The facilities that generate electromagnetic radiation can be roughly divided into five categories: 1, radio and television transmission systems, such as TV transmission towers and radio relay stations; 2. Wireless communication transmission systems, such as mobile phone base stations; 3. High-voltage power transmission and transformation systems, such as high-voltage lines and substations; 4. Electrified railways, such as maglev trains; 5, industrial, scientific and medical electromagnetic energy facilities, such as high frequency melting furnace; Harm of electromagnetic radiation Humans live in a huge electromagnetic field, and electromagnetic radiation is everywhere, so electromagnetic radiation is not as terrible as imagined. Only when the electromagnetic radiation exceeds a certain value will it have a negative impact on people's health. According to the electromagnetic radiation protection regulations issued by the State Environmental Protection Bureau, the electric field intensity is lower than 40 volts per meter, which should be safe. Even if it exceeds this value, it will not necessarily cause injury, which depends on the individual's resistance and the time and distance of contact. In addition, experts also pointed out that electromagnetic waves are everywhere, bringing infinite convenience to our lives. We should treat them correctly and make rational use of them. There is absolutely no need to worry too much. As long as proper shielding and protection are carried out, the radiation impact can be greatly reduced.
