Problem 2: mobile signal tower radiation distance is how much I say a fair word as long as there is a signal where there is radiation, the general tower station at least covers a radius of 3 kilometers which is the urban area of the ha, but also depends on the power of the base station opened up how big. I can only say that the closer the base station the greater the radiation ！！！！！ Look at the owner's discretion!
Question 3: If a mobile cell tower is installed on the roof of the home, is the radiation big? The impact is certainly there, electromagnetic radiation on the harm of people with each passing day, but this and inevitable. To send you a report:
Now science can not explain the relationship between long-term exposure to radiation and cancer, and can not provide relevant evidence. What can be said to understand is that the mobile signal transmitter (base station) antenna to transmit the maximum power is 20 watts, the emission frequency is 900 megahertz (or 1800 megahertz), to reach the human body is generally in the milliwatt scale; cell phone is the maximum emission power is 2 watts. When you play the cell phone by the radiation cell phone will be far greater than the base station.
There is radiation, but all in the national safety standards, will not have a bad effect on the human body. Communication facilities are approved by the local environmental protection bureau to build the tower, the power is very small, in the 200mW below, on the people basically no harm.
Experts say, don't look at the electromagnetic radiation pollution this term is a little strange, but it is very common in our lives. Can create electromagnetic radiation pollution pollution sources everywhere, there are television and radio transmission towers, radar stations, communication transmitters, substations, high-voltage power lines, and computers, cell phones, microwave ovens, electromagnetic cooker, and even the subway train we ride and so on can create electromagnetic radiation pollution.
Experts told us that some cities have built TV towers, because TV towers are a few hundred meters high, the radiation of the area has exceeded the height of residential housing, basically will not have an impact on the health of the public. Some high-rise buildings have antennas, like parabolic antennas, cell phone base stations and paging station antennas, these antennas have limited power and are controlled by the local radio management committee, so they do not have much impact on the residents.
China Unicom, China Mobile, China Telecom and other signaling towers. The height of signal transmitting pylons is generally over 45 meters, while the height of a typical residential building is 7 floors, about 21 meters, and the height of the pylon antenna is much higher than the existing residential buildings, which will not cause any harm to people's health.
Europe and the United States have conducted a large number of surveys and statistical analysis, the size of each survey varies, and the number of people investigated at one time has thousands of people, tens of thousands of people, hundreds of thousands of people and even millions of people. The locations of the surveys are in the field, for example, near power lines, substations, subway stations, and inside electric trains; or in factories, laboratories, offices, and homes. Surveys span a period of time of more than a decade or even decades.
The results of a large number of surveys are convincing that the probability of the occurrence of a variety of tumor lesions in the human body is closely related to the exposure to low-frequency magnetic field radiation. Experts from many countries in Europe and the United States and some *** institutions are convinced that low-frequency magnetic fields significantly increase the incidence of the following diseases: leukocytosis and leukemia (especially harmful to children), cancer, neonatal defects, breast cancer, brain tumors, malignant lymphomas, neurological tumors, astrocyte development, chronic myeloid leukemia, chromosomal aberrations, etc. Some reports also point out that in the presence of electromagnetic fields, the human body is exposed to a variety of neoplastic lesions closely related to the exposure to electromagnetic radiation. Some reports also indicate that a decrease in the secretion of certain hormones under the influence of electromagnetic fields may also be responsible for the development of breast tumors. Some investigation reports also pointed out that people who are often exposed to electromagnetic radiation, and then subjected to high temperatures, the risk of breast cancer in their bodies is greater.
Foreigners say:
Headaches, insomnia, dizziness, memory loss and cancer are just some of the health complaints of people living near cell phone towers in Bordeaux.
The Anastasiou family, 49, lived near the Bordeaux cell phone towers from the day they were built seven years ago. Since then, the Anastasiou family has suffered numerous health problems, insomnia, persistent headaches and dizziness, and their two dogs have been diagnosed with "tumors". 2000, Anastasiou was diagnosed with lymphocytosis and early leukemia. After numerous blood tests, doctors were unable to come up with a reasonable explanation for his condition. After a three-month stay abroad, Anastasio's condition inexplicably improved.
Not far from Anastasiou's house is another family with similar health problems, and although they live relatively far from the towers, they have been tested and found to be exposed to far more radiation than Anastasiou's. One of the family members said that he had been exposed to more radiation than Anastasiou. One member of the family said that he used 20 painkillers a week to relieve headaches that doctors could not explain. They often lose sleep at night, especially on Friday and Saturday nights, when the towers are busiest. "We feel particularly sick when we stay at home. Of course we give scientific proof, but we know that the problem must be with the towers because the problems started when we moved here two years ago, and when we moved away from here, all the symptoms disappeared automatically." Whether cell phones and cell towers are the cause of the health problems has yet to be studied. Voda - the company that set up the cell phone towers in Bordeaux - made a clear statement ...... >>
Question 4: How much radiation from mobile telecom towers harms the human body There is no evidence that base station antenna radiation affects the human body, and electromagnetic radiation is prevalent in current life. TV, induction cooker, cell phone in the ear, will produce radiation, so there is no need to panic about base station radiation. Some people even think that base station radiation can cause disease, in fact, it is completely psychological.
Generally speaking, a house, the bottom of the residential electromagnetic field strength to be smaller, the level of high residential electromagnetic field strength to be larger. Accordingly, the lower floors may have slightly weaker signals, and the higher floors have better signals.
Problem 5: mobile signal towers on the people how much harm China Unicom, China Mobile, China Telecom and other signal transmitting towers. Signal transmitting tower height is generally more than 45 meters, and the general height of the residential building is 7 layers, about 21 meters, the height of the tower antenna is much higher than the existing residential, will not cause harm to the human body.

Whether cell phones and cell towers are the cause of the health problems has yet to be studied. Voda, the company that set up the cell phone towers in Bordeaux, clearly states that the radiation intensity in the area around the towers is less than 667 times the recommended index. This guideline index is the result of discussions between the German International Commission on Non-Ionizing Radiation (ICNIRP) and the International Health Organization***. It assumes that "non-ionizing" radiation has no physiological effect on the human body other than heating. Although many studies have shown that cell phone signals alter brain wave patterns, ICNIRP insists that this is not proof of a "health threat" and that the headaches that many cell phone users complain of are "subjective".
In recent years, scientific studies around the world have pointed to the link between low-intensity microwave radiation (similar to the signals emitted by cell phones) and the health problems it causes, such as persistent fatigue, insomnia, and headaches. The intensity of radiation in the area around the cell phone towers in Bordeaux was measured at 70 microwatts per square centimeter using specialized equipment. The Latvian study showed that children exposed to radiation 100,000 times lower than the intensity of radiation in the area around the Bordeaux cell phone towers experienced the following symptoms: muscle fatigue, slowed reaction time, memory and concentration loss.
Many other studies have pointed to a link between radio radiation and leukemia. A study of people living near a television tower in Sydney showed an increasing incidence of leukemia in the local population. Excessive rates of leukemia have also been reported in the United Kingdom and Northern Ireland among people living near television towers.
The Chinese said
Recently, residents living in Beijing, Lanzhou and other places have reflected to the media, in their neighborhoods on the roof of residential buildings to establish the communication base station transmission tower will produce electromagnetic radiation, resulting in human beings appear ...... >>
Question 6: Is there any radiation on the human body from mobile signal towers installed on top of buildings? How much radiation? There is radiation, but there is no major harm to the human body.
The vast universe, the boundless starry sky, the space of electromagnetic waves than the space of the atmosphere, is infinitely large proportion of light years, countless extraterrestrial stars have shaped *** electromagnetic wave radiation source, its density is not air comparable. Cosmic space, the sun produces light radiation are insignificant, can imagine the power of electromagnetic waves. In the atmosphere, lightning, the world's broadcasting stations, communications (letter), navigation equipment, and intentionally or unintentionally created in the interference wave intertwined together, bustling full of space, people live in the sea of electromagnetic waves.
Electromagnetic waves are ubiquitous, and sources of electromagnetic radiation can be divided into natural and man-made sources of electromagnetic radiation. Lightning, sunspot activity, cosmic rays and other electromagnetic radiation, which is a natural source of electromagnetic radiation; and man-made sources of electromagnetic radiation are mainly various types of radio equipment, including industrial, scientific and medical equipment. We use the alternating current frequency of 50 hertz, one because the frequency is low, can not be spread in the air; two because the power is large, the cost of transmitting and receiving is too high, so in the wire transmission. But AC power in the generation of transmission use process, every moment in the production of a large number of electromagnetic waves.
To long-wave, for example, 30 kHz in one second to have 30,000 cycles, each wavelength will have 10,000 meters, a steady stream of diffusion to the surrounding area, is a band of electromagnetic waves is enough to scare people. Not to mention the universe is too much electromagnetic waves, with light years can not count the large team.
The launch and reception of useful electromagnetic waves, modulation and demodulation, is the result of a variety of frequency conversion. In particular, a variety of radio transmitters, signal sources, etc., the greater the power, the stronger the amplitude. That is, the ordinary radio, television, cell phones and other internal work of the various frequency circuits are interlaced, radiating electromagnetic waves, only their power is not big, the electromagnetic wave generated by the transmission will not be very far.
Humans live in the sea of electromagnetic waves, because of electromagnetic waves, human life is colorful.
The harm of electromagnetic waves on the body, compared to such as polite pollution, water pollution, food pollution, dust, etc., is insignificant. Long-term work in a high magnetic field, strong radiation environment, there is no occupational disease of electric radiation. Long-term living in the vicinity of various radio and television transmitters, various wireless communication transmitters, base stations, and other people in the vicinity of the decades have not seen abnormalities.
Electromagnetic waves have a great impact on people, the scientific sector has never stopped exploring and researching on it. National electromagnetic safety standards: long, medium and short-wave electromagnetic radiation less than 10 volts / m, ultra-short-wave electromagnetic radiation less than 5 volts / m, microwave electromagnetic radiation less than 10 microwatts / square centimeter, that is, the results of previous and modern scientific research. State-approved production of mobile telephones, wireless walkie-talkies, indoor wireless telephones, radio and television broadcast transmitters, wireless base stations, microwave and satellite communication devices, radar, radio remote control and other types of radio equipment, as well as, for example, microwave ovens, high-frequency eye lamps, medical magnetic **** vibration equipment, helium arc welders, radio frequency heaters, high-frequency thermal laminators, AC high-voltage power transmission lines, transfer switches, electric motors, Generators, televisions, computers, etc. are electromagnetic radiation, the harm to people is far below the national standards, can be used safely, will not cause harm to people. If you play the computer to watch TV and other close injury to the eyes, the main not electromagnetic wave injury, fatigue injury component accounted for more.
Objective conditions of the natural generation of electromagnetic waves, is constantly generated by the process of continuous attenuation, man-made electromagnetic waves, in recent years, although greatly increased, but in the electromagnetic wave family, this increase is insignificant. The scientific community said that the electromagnetic wave pollution is serious, mainly does not refer to the damage to people refers to the abuse of man-made electromagnetic wave, touch the intrusion, the occurrence of accidents increased to strengthen the management and so on.
In all the electromagnetic wave damage to the human body, the cell phone is the most serious, mainly because the phone in the call, is close to the ear and head, is the most sensitive parts of the human body. If you're not even afraid to use your cell phone, you should have no worries about anything else.
May you believe in science, respect science, do not fear electromagnetic radiation, fully enjoy life.
Question 7: What is the radiation of mobile signal towers and machine rooms in residential areas, how much should the safety distance, what should we do Hazards of mobile communication base stations on the human body
Mobile communication through the antenna sends electromagnetic waves, for electromagnetic radiation is the form of energy in the form of electromagnetic waves emitted by the source of radiation (antenna) into the space of the phenomenon, referred to as electromagnetic radiation. When electromagnetic radiation passes through the human body, its energy will be absorbed by the human body, and if this energy is too large, it will constitute a hazard to human health, and the human body will be exposed to such an electromagnetic radiation environment, which will have certain effects.
Electromagnetic radiation field area:
Electromagnetic radiation field area can be divided into near-area field and far-area field. In general, the antenna within 300 meters of the region are near-field area, in this region the electric field is much stronger than the magnetic field; and in the region greater than 300 meters, the magnetic field is much larger than the electric field. The far-field region is a weak field, and its electromagnetic field strength is smaller. Therefore, for a fixed source of electromagnetic radiation can produce a certain intensity of electromagnetic radiation, should pay attention to the protection of electromagnetic radiation near the field, including the protection of operating personnel and personnel in the environment of the near field, and is located in the near field of a variety of electronic and electrical equipment protection. In the far field, usually less harmful to people, the main factor should be considered is the protection of the signal.
Electromagnetic radiation hazard:
Due to the wireless communication network of RF radiation damage has a cumulative effect, so when in the radio frequency radiation, the human body will not be immediately harmed, only over time, the accumulation of a certain degree of harm to the human body. This cumulative process for the safety retention time. This is often the case for several years.
Signal tower damage to people, mainly electromagnetic radiation
The impact of electromagnetic waves on the human body and damage:
Electromagnetic wave allergy: refers to long-term exposure to electromagnetic wave environment caused by the nerve and allergy symptoms, the symptoms include headache, burning eyes, dizziness, vomiting, skin rashes, weakness, joint and muscle pain, ringing in the ears, paralysis, swelling of the face, The symptoms include headache, burning eyes, dizziness, vomiting, skin rash, weakness, joint and muscle pain, tinnitus, paralysis, swelling of the face, fatigue, lower abdominal contractions, arrhythmia, irregular heartbeat, and shortness of breath, in addition to the more serious symptoms of stroke, frustration, panic, confusion, imbalance, cramps, memory loss, and hypersomnia.
Most people have cancer-causing cells in their bodies that are destroying our immune systems, and data continues to show that exposure to electromagnetic waves for just a few minutes can increase the carcinogenicity of the original 5 percent to 95 percent. Prolonged exposure to electromagnetic waves can cause dizziness, memory loss, tinnitus, and other phenomena, while destroying the immune system and increasing the chance of cancer.
Regardless of whether the electromagnetic wave irradiation of all or part of the human body will be due to the thermal effect of the relationship between all or part of the body temperature rise, usually the blood flow in the body will play a diffusion of exclusion of the role of heat, but the part of the eye is difficult to exclude the heat through the blood flow, so it is easy to produce cataracts.
From Wuhan University Zhongnan Hospital, there is also news that animal experimental research shows that electromagnetic waves generated by communication equipment can damage the brain tissue of the fetus. Because the brain's activity is dominated by brain waves, brain cells are through brain waves to transmit signals. Cell phone and mobile communication base station all produce radiation for electromagnetic wave, since it can interfere with the radio communication and navigation system, it is also the same on the human brain constitute "pollution". This can damage fetal brain tissue and cause malformations; for adults, it can cause brain tumors.
According to the International Neurological Tumor Treatment Forum held in Guangzhou on April 19, 2006, experts pointed out that in the past 30 years, the incidence of brain cancer in urban men in China has increased by 100%, and the incidence of brain cancer in women has increased by 50%, which is directly related to the harms of electromagnetic wave radiation. In the past two years, the number of patients in outpatient clinics and wards of Glioma Clinic of Tiantan Hospital has become an upward trend, and the ratio of men and women suffering from the disease is 3:1. The reporter interviewed in the wards of the center found that there are many patients who are 40 years old or so, and seem to be strong and strong young and middle-aged people, and they usually feel good physically and are diagnosed with brain tumors only by accidental medical treatment or medical checkups.
The famous radar experts, China Electronics Technology Group, deputy director of the Science and Technology Commission, academician of the Chinese Academy of Engineering Wang Xiaomu said that the electromagnetic radiation on human health is certainly have an impact, including the electromagnetic radiation of the communication base station is the same. And this effect is not short-term can be found. Often in the environment of electromagnetic radiation, over time the harm to human health will also be very serious, and this harm is also multi-faceted, in addition to triggering dizziness and headaches and other diseases, long-term may also affect the quality of the next generation, such as the production of deformed children, the elderly get cancer chances, adults infertility, and so on, so it must be attracted the attention of the relevant departments.

Question 8: How harmful are mobile cell towers? This kind of is not tested by professionals, so how much radiation in the end, no one can give you an answer. And as for the ***, is not realistic, communication operators building signal towers are formal approval, there is no violation of the problem. I do not think there is too much need to dwell on this issue, now the city is full of transmitting towers, infrastructure is perfect, the signal will be more stable, generally this type of radiation will not affect human health, otherwise it is not possible to build if dense.
Question 9: How many meters away from the residential area of the mobile signal tower radiation is the most secure? Base station antenna directly opposite the direction of 10 meters away, 3 meters away from the vertical direction;
Mobile signal tower, refers to the low-power wireless antenna with the user's cell phone for communication, according to the size of its service range and the number of users, the transmitter power from a few watts to hundreds of watts ranging. Generally, base station antennas are installed on buildings or transmission towers that are 15-50 meters above the ground;
Mobile cell tower antennas radiate relatively weakly and are usually installed at the top of buildings, and most of the radiation released will be absorbed by the buildings, and won't be harmful to people living under the antennas of the towers.
