Radiation from cell phone towers may cause leukemia.
Worried about electromagnetic radiation
Seven years ago, since the mobile phone tower in Bordeaux was built, the 49-year-old Anstaf family lived near the tower. Since then, there have been many health problems in this family, such as insomnia, persistent headache and dizziness. Both of their dogs were diagnosed with "tumors".
In 2000, Anastacio was diagnosed with lymphocytosis and early leukemia. After numerous blood tests, the doctors could not give a reasonable explanation for his illness. After three months abroad, I got better for no reason. There is another family with the same health problems living not far from home. Although the family lives far away from the launch tower, after testing, the radiation intensity in their place is much higher than that in their family's home. One of the family members said that he used 20 painkillers every week to relieve headaches that doctors could not explain. They often suffer from insomnia at night, especially on Friday and Saturday nights, because the transmission tower is the busiest in these two days. "We will feel particularly uncomfortable staying at home. Of course, we have given scientific proof, but we know that the problems must have appeared on the launch tower, because these problems began to appear when we moved here two years ago. When we moved here, all the symptoms disappeared automatically. "
Two people died of cancer near the signal tower.
Residents living near the signal tower are four times more likely to get cancer than ordinary residents. Experts say that long-term exposure to radiation sources can lead to leukemia.
Since two cell phone towers were installed on the roof 10 years ago, six of the eight families living on the top floor of Berkeley Building in Bristol, England, have developed cancer one after another, and two of them have died. Recently, people named this building "The Tower of Death".
The cancer rate is 10 times of the average.
According to the British "News of the World" (65438+February 3rd), the average proportion of people suffering from cancer in Britain is 2%, while the probability of cancer among residents living at the top of the Death Tower is as high as 20%.
Of the 6 cancer patients, 5 were breast cancer patients (2 died) and 1 colon cancer patients. Among other residents, some people suffer from headaches and other diseases. Residents living near another signal tower also said that within three years, seven people died around them, four of whom died of cerebral hemorrhage and three died of cancer.
Many residents said that they were very worried that these signal towers would have a bad influence on children. There are three schools within 230 meters of the two signal towers. Three children with leukemia were found in a nursery. Three other leukemia children were found in the family living near the signal tower.
William & #12539 last year; Sir Stuart strongly appealed for banning the installation of signal towers near schools. Moreover, he himself does not allow his grandson to use his mobile phone in non-emergency situations.
The risk of cancer near the tower is four times higher.
In August this year, the International Journal of Cancer Prevention reported that residents living near cell phone towers are four times more likely to get cancer than those living far away from cell phone towers. Excuse me, what harm does the electromagnetic wave generated by the cell phone signal transmission tower installed on the roof have to the human body?
Suggestions or solutions:
At present, all countries in the world are still studying and verifying this problem. It has not been proved to be harmful to human body, but it is not certain that it is harmless to human body. Mainly focused on the issue of transmission power.
Now it is generally said that it still has an impact on the human body, because in many cases, the power is different, and it is possible to emit a lot of power for a period of time, which is definitely harmful to the human body. Moreover, although the power requirements of mobile phone base stations are required internationally, it is difficult to guarantee them in the actual work process.
Therefore, people should stay as far away from mobile phone base stations as possible.

At present, the number of base stations of China Mobile has exceeded 200,000, and the number of PHS base stations of China Telecom and China Netcom is as high as 6,543.8+0,000. Moreover, with the construction of 3G networks, this number will rise. The data of Beijing Radiation Environment Management Center shows that mobile communication base stations, TV towers, radio stations and high-voltage power transmission and transformation systems have become the main sources of electromagnetic radiation pollution in Beijing. Is the radiation generated by so many base stations harmful to human body, and to what extent? At present, the relevant parties have their own words.
Telecom operators believe that radiation is harmless to human body. Their reason is that the standards of mobile communication base stations strictly conform to international and national standards, and the main standards are the Regulations on Electromagnetic Radiation Protection and the Hygienic Standard for Environmental Electromagnetic Waves issued by the State Environmental Protection Administration and the Ministry of Health. The national standard requires that the electric field intensity is less than 12 volts per meter or the power density is less than 40 microwatts per square centimeter. Telecom operators have carried out environmental assessment during the erection of base stations, and the results are all under this standard. Moreover, from foreign reports, there is no accurate data showing that mobile communication base stations will have radiation effects on nearby residents. However, as the owner and manager of the base station, the detection results of telecom operators are not convincing.
Some third-party experts expressed the opposite view. Wang, a well-known radar expert, deputy director of the Science and Technology Committee of China Electronics Technology Group and academician of China Academy of Engineering, said that electromagnetic radiation definitely has an impact on human health, including electromagnetic radiation from communication base stations. And this effect can not be found in a short time. Frequent exposure to electromagnetic radiation will be very harmful to human health over time, and this harm is also multifaceted. In addition to causing dizziness and headache, it may also affect the quality of the next generation for a long time, such as deformed children, so it must be paid attention to by relevant departments.
However, Professor Li Kaibao, chairman of the Radiation and Protection Branch of the Chinese Medical Association, said that the radiation of the communication base station is very small and will not affect human health, so there is no need to worry. In general, the base station antenna is installed on a building or tower that is 0/5 ~ 50 meters above the ground. The radio frequency emitted by the base station antenna mainly extends in the horizontal direction and rarely emits in the vertical direction. Therefore, a person may only be affected by radiation near the horizontal direction of the antenna, and some people's discomfort symptoms may also be caused by psychological reasons.
From the discussion of two experts, it can be concluded that base station radiation is really harmful to human body at high power, and if it is lower than a certain value, the harm can be ignored. However, there is no specific standard definition of the radiation of mobile communication base stations in China except the Regulations on Electromagnetic Radiation Protection and Hygienic Standard for Environmental Electromagnetic Waves. According to Ye Lin, director of the High-tech Development Division of the Science and Technology Department of the Ministry of Information Industry, at present, the State Environmental Protection Administration is studying the electromagnetic radiation standard of base stations with the Ministry of Information Industry.
In addition, Mr. He Guili, director of Thiel Laboratory, said that the standards on the harm of mobile phone radiation and base station radiation to human body have been formulated and are currently waiting for approval by relevant state departments.
In foreign countries, ICNIRP (Non-ionizing Radiation Protection) International Non-ionizing Radiation Protection Association gives the reference index of power intensity. If the power intensity is lower than this value, it can be considered that the standard is met. These guidelines vary according to the frequency. In the frequency range of 10MGz to 300 GHz, the guidance standard also varies from 2 W per square meter to 10 W accordingly. At present, in the 900 MHz GSM mobile phone band, this guideline is 4.5 W per square meter, while in the GSM 1800 band, this SAR index can be relaxed to 9 W per square meter, and for 3G base stations using the 2000 MHz band, this guideline is further relaxed to 10 W per square meter.
The gap between fact and theory.
We can't doubt the reality that communication equipment manufacturers and mobile communication operators actually abide by these standards. However, the environment for setting up base stations varies widely. Can operators pass rigorous tests and abide by standards in specific deployments?
It is reported that in Huilongguan Community, the transmission power of the GSM base station set-top box installed by Beijing Mobile is 20W. For the 3G base station to be deployed soon, China Mobile also requires that the transmission power of the set-top box of the base station provided by the equipment manufacturer should not be less than 20W/ carrier, and the transmission power of RRU should not be less than 10W/ carrier.
In this regard, we consulted relevant technical experts, and Zhang Junfeng, an engineer in the wireless communication research department of the Institute of Telecommunications, Ministry of Information Industry, said that when the top of the base station transmits through the feeder, the transmission power will increase by 10 dB, but the signal strength will drop rapidly after leaving the base station antenna. Generally, the radiation intensity is about -50dbm when it is 30 meters away from the antenna, while the signal of GSM mobile phone can be connected at -80dbm.
According to Mr. Shi Meixian, an expert from Telecommunications Research Institute of the Ministry of Information Industry, the transmission power of GSM mobile phones is generally 2W, which is equivalent to 33dbm. Thus, if far away from the base station, the radiation intensity of the base station is much less than that of the mobile phone, which can be regarded as harmless.
But often these base stations are close to residential buildings, and some even set up on the roof. At present, there is no accurate data on the specific correlation between the distance from the base station antenna and the signal intensity attenuation, but it is obvious that the closer to the antenna and the longer the time, the more obvious the health damage caused by radiation.
What I want to tell you is:
There are two sows in my family. Since the base station was built, a sow has bred twice and is not pregnant. This sow has been bred for several years, and it is always bred at one time. The other sow has bred three times, but she is not pregnant. This sow has been breeding for a long time, but it hasn't been bred twice.
The neighbor's sow got sick before giving birth, and it will be full moon after giving birth. Or a bottle of intravenous drip every day. They are a little far from the base station, about 50 meters.
Farmers have no education, and they all think it is bad luck this year, but they didn't expect it to be the influence of the base station.
When I left home, I sat on the train and found that many rural areas were built next to the house, just like the base station next to my home.
Move these unscrupulous people, regardless of the peasants' lives.
Ladies and gentlemen, if there is a base station near your home, if there happens to be a pregnant woman in your home, please act quickly.
Cherish your life and stay away from the base station!
