Protective measures against electromagnetic waves：

According to the attenuation characteristics of electromagnetic wave with distance, in order to reduce the harm of electromagnetic wave to residents, the workplaces and facilities which transmit electromagnetic wave with high power and may produce strong electromagnetic wave, such as TV stations, radio stations, radar communication stations, microwave transmission stations, etc., should be located as far away as possible in remote suburban counties or in high terrain far away from residential areas. District. Facilities, such as substations, which must be set within the city, adjacent residential areas and residents'regular activities, should be kept at a safe distance from the residential areas to ensure that their boundaries meet the requirements of environmental electromagnetic health standards. At the same time, the electromagnetic radiation source should be shielded by copper, aluminium, steel and other metal wires or polymer films, which can shield, reflect or absorb electromagnetic waves, so as to limit the electromagnetic radiation energy to the prescribed space.

High voltage transmission lines, especially ultra-high voltage transmission lines, should be far away from crowded areas such as residential buildings, schools, sports fields and so on. When using a computer, low-radiation display should be selected, and the distance between the human body and the front of the display screen should not be less than 75 cm, and the side and back should be no less than 90 cm. It is better to install shielding devices.

The density of mobile communication base stations should be strictly controlled to ensure that the antennas of various mobile communication base stations set up in urban areas are higher than those of surrounding buildings. No transmitting antenna should be established in a certain area around kindergartens, school buildings, hospitals and other buildings.

In order to alleviate the indoor electromagnetic pollution and its harmful effects, it is necessary to ventilate the room regularly and keep the indoor air unblocked. Scientific use of household appliances: for example, when watching TV or home cinema, listening to the combination of audio, should maintain a relatively long distance, and avoid all kinds of electrical appliances at the same time open; the use of computers or electronic game consoles should not last too long.

When using a mobile phone, try to reduce the call time; the top of the antenna should deviate from the head as far as possible, try to lengthen the antenna; install headphones on the mobile phone, etc.

In addition, you can take a certain amount of vitamin C every day or eat more fresh vegetables rich in vitamin C, such as pepper, persimmon pepper, toon, cauliflower, spinach and so on; eat more fresh fruits such as citrus, jujube and so on. We should also pay attention to eating more foods rich in vitamin A, C and protein, such as tomatoes, lean meat, animal liver, bean sprouts, etc. To some extent, these dietary measures can play an active role in preventing and mitigating the harm caused by electromagnetic radiation to human body.

Electromagnetic radiation is a new kind of environmental pollution which has been known for nearly thirty or forty years. Now people are still at the stage of understanding and Research on electromagnetic radiation. Because it is invisible, intangible and difficult to detect, it is easy to arouse people's doubts. In addition, some reports about electromagnetic radiation are not objective and scientific, which leads to unnecessary misunderstanding and panic. Generally speaking, to determine whether electromagnetic radiation pollutes the living environment, we should take into account the intensity of electromagnetic radiation, the direction of main radiation, the distance from the radiation source and the duration. Therefore, while strengthening electromagnetic protection, we should also adopt a scientific attitude to the problem of electromagnetic wave pollution, objectively analyze and seriously deal with it. We must not follow suit. Irresponsible and blind exaggeration leads to confusion in people's understanding. Of course, with the development of science and technology, people's understanding of electromagnetic pollution and its hazards will gradually deepen, and many mysteries will eventually be uncovered.
