Will, the most common in life is the electromagnetic radiation of electrical appliances. Such as: computers, televisions, microwave ovens, hairdryers, refrigerators, cell phones and so on. Researchers through experimental studies found that electromagnetic radiation in front of the computer monitor usually only need a fiber glass can block, if there is no fiber glass, try to maintain a distance of more than 30 cm from the computer screen.
The amount of electromagnetic radiation will then be lower than the safe value. Secondly, the mainframe of the computer radiation than the monitor, because the mainframe with the radiation of the part of the motor, electric coils, electric fans and other parts of these parts to maintain a distance of more than 60 centimeters from the human body.
While there is a lot of electromagnetic radiation in life, but we do not have to be overly nervous. Scientific understanding and prevention of electromagnetic radiation pollution is very necessary. In general, electromagnetic radiation is not strong, but because it has a cumulative effect, so in life, we should also pay attention to, try to stay away from the source of radiation.
A variety of household appliances, office equipment, cell phones, etc. should try to avoid prolonged operation. When operating, pay attention to maintain the distance between them. When the appliance is suspended, it is best to turn off the power, not in a standby state, even if it is weak electromagnetic radiation, a long time will produce radiation accumulation.
Home appliances should also not be placed too centralized, as far as possible, decentralized placement. In addition, you can eat more carrots, tomatoes, kelp, lean meat, animal liver and other foods rich in vitamin A, vitamin C and protein, can strengthen the body's ability to resist electromagnetic radiation.

Artificial Electromagnetic Radiation:
Artificial Electromagnetic Radiation arises from a number of artificially created systems, which produce a variety of different wavelengths and frequencies of electromagnetic waves during normal operation. The greater impact of the power system, radio and television transmission systems, mobile communication systems, transportation systems, industrial and medical research high-frequency equipment.
1, the power system
Economic development has led to a variety of electrical equipment is increasing, the electrical load has increased dramatically, the size of the power grid is rapidly expanding, high-voltage transmission lines and substations are increasing. By high-voltage, ultra-high-voltage transmission and distribution lines, substations and power transformers and other alternating magnetic fields generated in the near-area field will produce serious electromagnetic interference.
2, radio and television transmission system
Radio and television transmission towers are the largest source of electromagnetic radiation in the city, most of these devices are built in the center of the city, many radio and television transmitting equipment is surrounded by residential areas, the formation of a strong field in the local residential living areas.
3, mobile communication system
Mobile communication base station is the main source of electromagnetic radiation. With the rapid development of telecommunications, the number of mobile base stations continues to increase, in order to prevent interference, the base station height gradually decreased, the probability of reflecting the electromagnetic waves emitted to the residential building increases, the distance between the base station and the base station is gradually reduced, the distribution is becoming more widespread, so that the level of electromagnetic radiation is increasing.
4, transportation system
Transportation includes rail, trolley bus, electrified railroad, automobile, subway and so on. This source of radiation is mainly in the form of conduction, induction, radiation and other forms of electromagnetic radiation, such as the ignition system of automobile engines will produce a very strong broadband electromagnetic noise.
5, industrial and medical science and technology high-frequency equipment
Industrial and medical research high-frequency equipment produces strong radiation on the environment and human health will have an adverse effect.
