Influence of electromagnetic radiation from base station on human body

Influence of electromagnetic radiation from base station on human body

The influence of base station electromagnetic radiation on human body, radiation, seems to be a very scary problem. For example, in various sci-fi movies, the doomsday crisis brought by nuclear radiation is everywhere. Next, I will send you a message about the influence of electromagnetic radiation from base stations on human body.

Influence of electromagnetic radiation from base station on human body 1 1. The more communication base stations, the greater the radiation?

In fact, the radiation of the communication base station is not as big as that of a room full of household appliances.

In life, microwave ovens, computers, televisions, hair dryers, radios and other household appliances also produce electromagnetic radiation. Compared with these common household appliances, the radiation of cellular base stations is very small.

Because the antenna coverage of the communication base station is wide, and the radiation power is scattered within several square kilometers of Fiona Fang, and the distance from the antenna to the human body often exceeds 10 meter, it has little impact on the human body.

2. Is the closer to the communication base station, the greater the radiation?

The radiation of the communication base station belongs to "black under the lamp", and the distance is not necessarily large.

Many citizens think that the closer to the communication base station, the greater the radiation, so they are opposed to building a communication base station in their own community or on the roof. In fact, the electromagnetic wave of communication base station is mainly emitted in the horizontal direction, and the vertical direction is obviously weak, so the power density directly below the base station is often the smallest. Just like an "oil lamp", the darker the lamp, the greater the outward brightness.

Which base station radiates more, 3.4G or 5G?

Network speed-up has nothing to do with base station radiation increment. 4G and 5G networks are faster, not by enhancing the signal transmission power of communication base stations, but by expanding the transmission bandwidth, just like widening highways.

In the 4G era, the frequency bandwidth has been greatly improved, and users feel that the network speed is faster, but the radiation standard of 4G communication base stations has not changed, and it is still lower than 40 microwatts /cm2. The same is true for 5G communication base stations. Moreover, the denser the coverage of communication base stations, the better the reception of mobile phone signals, and the smaller the electromagnetic radiation received by users. Therefore, with the continuous construction of 4G and 5G networks, there are more and more communication base stations with better signals and less radiation.

4. What did the academician say?

Recently, Wu, an academician of China Academy of Engineering, said at the 5G high-end dialogue forum of the Digital Expo hosted by China Unicom that many people mistakenly thought that the base station was in danger of electromagnetic radiation. The radiation standard of 4G base stations in the United States is 600 microwatts per square centimeter, while that of China is only 40 microwatts, which is 10 times stricter than that of the United States. From the base station 10 meter, the radiation is only 1.5 microwatts, while the microwave oven at home radiates 168 microwatts. The radius of the 5G base station is smaller and the power is lower than that of 4G.

Influence of base station electromagnetic radiation on human body 2 What is base station radiation?

Base station radiation refers to the radiation emitted by mobile communication base station facilities. In the mobile communication system, the transmission and reception of space wireless signals are realized by the transmitting antenna of the mobile base station. When transmitting signals, the transmitting antenna of the transmission tower has a certain intensity of electromagnetic radiation.

As for how much influence the radiation of base stations will have on human body, many international organizations are still studying it. However, since the base stations were put into use in the last century, there is no clear research conclusion or actual case to prove that the radiation of base stations will have an impact on human body, so there is no need to panic about the base stations.

Harm of base station radiation to human body

The signal radiation of the base station is electromagnetic radiation, non-ionizing radiation, which attenuates greatly in the process of atmospheric propagation, and the harm to human body is almost negligible. Moreover, the electromagnetic radiation of the base station is smaller than that of household appliances, so there is no need to worry about the radiation problem of the base station.

The radiation pattern of the base station is basically like this. Every sector of the base station has a broadcast frequency, which transmits at full power 24 hours a day. This frequency mainly transmits some information of the sector. Other frequencies are mainly transmitted during the call, and the transmission power can be automatically adjusted according to the distance of the caller.

Radio frequency radiation can be regarded as continuous radiation, and other frequencies are pulsed radiation. Many international research institutions believe that pulse radiation is more harmful than continuous radiation, but there is no conclusion. The base station has both continuous radiation and pulse radiation.

Regarding the hazards of pulse radiation and continuous radiation, the Center is cooperating with relevant international institutions to prepare further analysis and research.

Influence of electromagnetic radiation from base station on human body 3 Radiation is everywhere, so be careful of ionizing radiation.

What you may not know is that radiation itself is not a "derogatory term", but a scientifically defined neutral word. In real life, radiation is everywhere. As long as it is above absolute zero, it will transfer energy to other objects in the form of electromagnetic waves and particles, which is radiation. Even our human body is actually a "radiation field". Flowers, plants, bricks and stones on the roadside actually have radiation.

There are two kinds of radiation, namely ionizing radiation and electromagnetic radiation. Generally speaking, "ionizing radiation" is harmful to human body. Ionizing radiation can also be divided into natural radiation and artificial radiation according to sources: natural radiation includes cosmic rays, earth's primary radionuclides, decay products of radon in the air and various naturally occurring radionuclides; Artificial radiation includes medical X-rays, radioactive dust produced by atmospheric nuclear weapons tests, radioactive waste discharged by nuclear industry and industrial gamma rays.

In daily life, we are most exposed to ionizing radiation, such as fluoroscopy, DR, CT and so on. However, due to the short contact time and small dose, these ionizing radiation will not have much impact on the human body, and the safety factor is high. The source of nuclear radiation will cause serious radiation damage to human body and even life-threatening. But ordinary people will not be exposed to such ionizing radiation, as long as they are careful not to approach places with electromagnetic radiation slogans.

Electromagnetic radiation is less harmful, so there is no need to worry.

Electromagnetic radiation, also called electron y fog, is composed of electric energy and magnetic energy transferred in space, and this energy is produced by charge movement. Electromagnetic radiation includes many kinds of radiation, such as base station signal, visible light, microwave oven radiation, mobile phone and router radiation.

Electromagnetic radiation will not cause ionization when it penetrates an object, so it will also cause destructive harm to the human body. Although some scientists believe that when electromagnetic radiation exceeds a certain level, it will cause certain harm to human reproduction, nervous system and immune system, but there is no real research result as a demonstration. In fact, under the cover of all kinds of electromagnetic radiation we are usually exposed to, it will generally not cause certain harm to the human body.

In this regard, Liu Xiaoyong, deputy chief engineer of the National Radio Monitoring Center, said, "At present, there is no evidence that non-ionizing electromagnetic radiation such as mobile phones and base stations is harmful to the human body within the standard range." In addition, the radiation standards of domestic base stations are stricter than those of the United States, Japan and Europe. The radiation exposure limit of mobile phone frequency band in China is 24 hours a day for 6 minutes, and the average power density is 40 microwatts/cm2. The standard in the United States, Japan and other countries is 600 microwatts per square centimeter.

Take responsibility and eliminate the "radiation demon theory"

The reason why some people are still talking about radiation discoloration is that they know too little about radiation. After all, although it is an era of knowledge explosion, people have not only acquired conventional knowledge, but also been "poisoned" by junk knowledge.

The "base station radiation dispute" is not a case, but a frequent negative event. In order to prevent similar incidents, all parties must bear the responsibility. For example, relevant departments should assume the responsibility of popular science, operators should make clear the radiation level and conduct tests to eliminate doubts, and residential properties should actively cooperate with the work and carry out publicity.
