Mobile base station in the area will have a base station radiation
Mobile communication base station will bring radiation pollution? Mobile base station to beautify the antenna will pose a health hazard to the human body? In order to help readers to understand more deeply the mobile communication base station radiation problem, as one of the high-tech products, mobile communication technology is unfamiliar to the general public. And the lack of awareness of mobile communications, it is the source of fear of the base station radiation. Coupled with the academic circles inevitably exist some disputes, domestic and foreign media have some sensational reports, which caused some inexplicable fear and contradiction among the people.
We live all the time in electromagnetic radiation, but only the electromagnetic radiation over a certain frequency and power caused by "electromagnetic pollution", will harm the human body. The interaction between the electric field and the magnetic field produces electromagnetic waves, electromagnetic waves emitted into the air or convergence phenomenon, called the electromagnetic radiation.
In fact, human beings are living in electromagnetic radiation environment all the time. Because the earth itself is a large magnetic field, the surface of the heat radiation and lightning can produce electromagnetic radiation, the sun and other planets from the outer space to generate an endless stream of electromagnetic radiation. Although electromagnetic radiation is widespread, but the vast majority of cases are not terrible. When the energy of electromagnetic radiation (said its size field strength) is controlled within certain limits, it is beneficial to the human organism, and other organisms, it can accelerate organism microcirculation and prevent the occurrence of inflammation, but also promote the growth and development of plants.
Electromagnetic radiation is harmful to human body mainly depends on two factors: first, look at the mobile base station to beautify the electromagnetic radiation frequency of the antenna, the two is to look at the size of electromagnetic radiation power. Only when these two factors more than a certain allowable value and cause radiation pollution, it is possible to have a negative impact on the human body.
Therefore, electromagnetic radiation is not directly equivalent to electromagnetic pollution, but also can not directly linked to human health.
The radiation frequency of the base station is about 900 MHz, which is similar to that of the TV. The sending and receiving power only ten to twenty MW, not enough to constitute radiation pollution.
So, we live and work in the environment where the electromagnetic radiation is relatively large? This mainly has:
(1) computer 0.61.5 meter distance;
(2) the room in the TV, audio and other home appliances more concentrated place;
(3) around the industry, science, medicine and electrical equipment and VDT; (4) around high-voltage transmission lines and equipment.
Mobile communication base station is also through electromagnetic wave transmission of information, but compared with the computer, home appliances and professional electrical equipment, etc., the base station does not belong to one of the stronger radiation source. Especially based on the application of digital technology, the radiation intensity of modern mobile communication is further controlled.
At present, our country's integrated landscaping antenna mobile communication base station standards are mainly in reference to the National Environmental Protection Agency and the Ministry of Health issued the "electromagnetic radiation protection regulations" and "environmental electromagnetic wave health standards". Specifically, the national standard requires that the electric field intensity less than 12 V / m or that the power density is less than 40 per square centimeter. Compared with the developed countries in Europe and America, this standard should be much more strict.
And mobile communication base station radiation frequency of about 900 MHz, and the frequency of the radiation is basically equivalent to the tv. Mobile communications is now taking a micro cellular technology, whether it is issued or received power is very low, only 10 MW, 20 MW energy level, is not enough to cause radiation pollution.
