You must know these common knowledge about electromagnetic radiation!
Everyone knows that making phone calls, playing games, using WeChat, chatting on QQ, and so on all require network signals, but where does the signal come from? Of course it's a communication base station! But after the construction of the base station, people will worry that the radiation from the base station will affect their health, leading to complaints and even obstructing the construction of the base station; Don't build or demolish it, everyone is complaining about poor phone signal, which affects daily life.
The farther away from the base station, the greater the radiation of the mobile phone. A base station and a mobile phone are like two people talking, and radiation is like volume. The farther away you are, the louder you need to shout; The closer you are, the more you can speak softly. Therefore, the farther the mobile phone is from the base station, the weaker the received signal from the base station. The mobile phone needs to emit stronger electromagnetic waves to maintain communication with the base station, and the radiation from the mobile phone is greater.
2. The base station will not affect the physical health of nearby residents. The process of electromagnetic waves propagating in the atmosphere attenuates greatly, and penetrating walls will cause sharp attenuation. If the construction of base stations meets national safety standards, it will not affect the health of residents.
3. The radiation from base stations is much smaller than that from mobile phones. The distance between base stations and people is relatively long, and the electromagnetic radiation of base stations will weaken as the transmission distance increases. And people have close contact with mobile phones, so the impact of mobile phone radiation on people is much greater than that of base stations.
4. The radiation of the base station is much smaller than that of sunlight. The radiation power of urban base stations is generally 30-300W. According to the inverse ratio between the radiation intensity received by the human body and the square of the distance, the radiation power density of 300W at a distance of 10m is only 0.2387W/m2. Physicists have already calculated that the radiation power density of sunlight on Earth is about 1000 W/m2, and the radiation of sunlight is thousands of times that of base stations. Therefore, in terms of electromagnetic radiation, base stations are much smaller than sunlight.
