In fact, electromagnetic radiation pollution has been recognized as the world's radioactive pollution, water pollution, air pollution, noise pollution, one of the major sources of pollution. The United Nations Conference on the Human Environment has listed it as one of the environmental protection projects. May 6 this year, the State Environmental Protection Administration in the "national electromagnetic radiation environmental pollution survey report" on the point that: electromagnetic radiation environmental pollution does exist, the State has formulated the electromagnetic radiation environmental protection measures, and requires the key electromagnetic radiation environmental pollution sources to carry out environmental impact assessment.
According to the damage caused by electromagnetic radiation on the human body, the State Environmental Protection Administration decided to increase the management of electromagnetic radiation, and the management of electromagnetic radiation environmental pollution into the normal work schedule. Experts have confirmed that under electromagnetic radiation, headaches, allergies, insomnia, chest pain, eye damage, neurasthenia; anemia, sexual dysfunction and other disorders, with the increase in radiation intensity, but also cause cellular aging, inhibit the body's immune system, which can cause genetic mutations and chromosomal aberrations, prompting the activation of viruses or the release of the virus to the point of causing cancer. Of course, its severity depends on the type, intensity and speed of the radiation, even if the tissue degeneration and cancer, but also accumulated for many years before the reaction, once found, it is difficult to treat.
The most direct harm to human and biological muscle is high-frequency electromagnetic microwave radiation, because it can penetrate the surface layer of the organism and direct heating of internal tissues, and the internal tissues of the organism is difficult to dissipate heat, often the surface of the muscle is nothing, while the internal tissues are severely burned, we usually know the microwave oven heating is the principle of a typical example can be corroborated by a few years ago in the scenic Emei Mountain, a microwave pollution incident occurred in the scenic Emei Mountain. A few years ago, a microwave pollution incident occurred, in the face of the microwave transmission station on the slope, due to long-term exposure to radiation, pine trees and other natural vegetation all withered and died, while the other side of the mountain, vegetation is lush.
Research by scientists in the United States and Australia has also demonstrated that microwave radiation from cell phones can cause physiological damage. As a result, these two countries have banned the erection of transmitting antennas near schools and residential areas.
Similar things have happened in China, in Guangzhou and Shenzhen, due to the electromagnetic waves emitted by mobile communication equipment near the airport and serious interference with the satellite navigation system, there have been a number of accidents in which the aircraft equipment is not working properly. In some occasions to play the cell phone, but also can cause electrical locomotive derailment, so that some medical equipment such as cardiac pacemaker malfunction. Some National People's Congress deputies called on the country to legislate as soon as possible to clean up the electromagnetic public nuisance.
Beijing mobile communication base stations become the main source of electromagnetic radiation pollution
Because of the fear of electromagnetic radiation close to the mobile communication base station jeopardizes their own safety, Fengtai District, Beijing, Shijuanzhuang top of the XiuXinYuan residents have repeatedly found the relevant departments to request the removal of the base station. The top of the Xiu Xinyuan district residents of the concern is not unfounded, the Beijing Municipal Radiation Environment Management Center data show that the mobile communication base station and television transmission towers, radio broadcasting stations, high-voltage transmission and substation systems, etc. *** with the main source of electromagnetic radiation pollution in Beijing.
On March 19, 2005, Beijing Unicom opened 152 GSM network base stations in just two hours. Following the network coverage rate of 99.99% in the eight districts of the city, the number of base stations and repeater stations in the suburbs of Beijing Mobile has grown to more than 2,000 as of May 2005. At present, the number of base stations of SmarTone in Beijing is also more than 16,000, and according to the plan, the number of SmarTone base stations will reach more than 20,000.
In response to the problem of electromagnetic radiation from mobile base stations in Beijing, experts from the Beijing Municipal Environmental Protection Bureau said that, in addition to strict compliance with the State Environmental Protection Administration's "Provisions on Protection against Electromagnetic Radiation" and other relevant national laws and regulations, since April 1, 2000, Beijing has formally implemented the "Beijing Municipal Mobile Telecommunications Construction Project Environmental Protection Management Provisions" (Trial), which provides detailed regulations on the construction and use of mobile telecommunication base stations. The regulations require that: mobile communication stations (including mobile telecommunication stations) are to be used for the construction of mobile telecommunication base stations. The regulations require that: the electromagnetic radiation level of the proposed location and the surrounding environment should be monitored before the construction of the mobile communication station (station), and no mobile communication station (station) shall be constructed where the power density of its public exposure export limit is greater than 40 μW/cm2; the minimum permissible height of the outdoor antenna of the cellular mobile communication base station shall be determined by the approved Environmental Impact Approval Sheet, but it shall not be less than 25 meters in general; in the area where the high volume of voice traffic The minimum permissible height of the outdoor antenna of the base station constructed in a densely populated area shall not be less than 16 meters; when the outdoor antenna of the cellular mobile telecommunication station is installed on a sensitive building, the antenna shall be installed in the center of the roof of the building or on the top of the elevator room of a high-rise building, and the distance between the antenna and the roof of the building shall not be less than 2.5 meters. As long as the above laws and regulations are strictly adhered to, electromagnetic radiation from mobile communication base stations will not jeopardize human health.
Experts from Beijing Radiation Environment Management Center suggest that mobile communication companies should pay attention to the following matters when choosing the address of the base station: avoid building stations in the most environmentally sensitive areas such as kindergartens, schools, hospitals, and elderly people; conscientiously abide by the content of the "Regulations on Environmental Protection Management of Mobile Communication Construction Projects in Beijing" (for trial implementation), and try to set up the location as reasonable as possible, with due consideration to the psychological tolerance of the residents; take the initiative to fulfill the requirements of environmental protection; and take the initiative to implement the "Environmental Protection Management Regulations". psychological tolerance of the residents; take the initiative to fulfill the environmental protection procedures, and timely release the environmental protection monitoring data to the public, so as to dispel people's ideological concerns, and at the same time, help the construction unit to protect its legitimate rights and interests in accordance with the law; enjoy the resources **** and minimize the duplication of the construction of the base stations; strengthen the research and publicity and explanation of the relevant aspects of electromagnetic radiation, respect the public's right to know, and set up an effective system of public information and communication, and Strictly enforcing the existing electromagnetic radiation protection standards and regulating the construction behavior of facilities accompanied by electromagnetic radiation generation, in order to obtain public understanding and support.
Even so, Professor Zhao Yufeng of the Indoor Environment Monitoring Working Committee of the China Interior Decoration Association still reminds residents not to take electromagnetic radiation around them lightly. Prof. Zhao Yufeng said: radiation intensity close to the standard, does not exceed the standard does not mean harmless.
Although from the current mobile base station monitoring situation, a single base station rarely exceeds the national standard, and most of them are far below the national standard, but if the same area of the base station built more, the power is too large, the intensity of electromagnetic radiation in the region or the possibility of exceeding the standard. Coupled with the impact of high-voltage lines, TV towers and other small areas, as well as home furnishing materials and electrical factors, in fact, many residents at home the intensity of electromagnetic radiation has far exceeded the national standard. And because the general environment of electromagnetic waves on people is a long-term effect, the research on it is also a long process. On the results of the current study, how much radiation on the body will constitute a hazard is still difficult to draw conclusions. Insiders emphasize that the degree of influence of electromagnetic waves on the human body in addition to radiation intensity, frequency, time, environmental factors, etc., but also with the individual's physical condition. In addition to the elderly, children, pregnant women and other people sensitive to electromagnetic radiation, different people or the same person at different ages on the tolerance of electromagnetic radiation is not the same. Therefore, the radiation protection standard is only a relatively safe range.
