Radar station, communication transmitting station, substation, high-voltage line, electronic instrument, medical equipment, automation.
Equipment, computers, mobile phones, microwave ovens, induction cookers and even subway trains will all cause electromagnetic radiation pollution.
Experts from the National Radio Interference Standardization Committee said in an interview that electromagnetic radiation
The intensity of electromagnetic wave is long wave, medium wave, short wave and ultrashort wave, and the frequency of microwave increases in turn.
The higher the frequency, the greater the impact; Second, look at the distance. The closer the distance, the greater the harm to people, especially high power.
Under high-voltage lines or near high-power transmitting stations, the harm to human body is more obvious. In addition, it depends on the angle.
The emission of electromagnetic waves is directional, and the radiation received at different angles is also different.
These factors, combined with the detection of labor protection agencies, show that mobile phone base stations and paging stations
Antennas are generally built on high-rise buildings, and generally live in buildings because of the refraction of barriers between floors and surrounding buildings.
People and nearby residents will not have adverse effects. Of course, if you happen to be at the same height as the cell phone antenna.
On a plane, and the distance is only 10-20 meters, the impact is much greater. The power of radio and television transmission towers is large, which has a slight impact on the surrounding residents.
