In the high-voltage tower diameter of 1.6 kilometers have an impact! Especially affects children and pregnant women especially! The proportion of children with deformities is 4 times higher (than the proportion of those who do not live under high voltage).The effects within 300 meters are very serious. It can cause cancer. Leukemia. The prevalence of leukemia in young children increases several times. It's a problem that can't be ignored! But the developers are now saying that there is no problem beyond 18 meters from the house. It's impossible!!! France. JAPAN. The United States and other advanced countries already do not build houses within 600 meters of high-voltage electricity. And people who already live within 600 meters of high voltage towers are given high compensation (because of complaints from the public). However, this neighborhood in Dalian seems to be in the castle of high voltage electricity. And the price is about 6000.

Electromagnetic radiation, how much do you know?
There is a complex causal relationship between electromagnetic waves and living organisms. In recent years, some people have put forward the theory that external electric fields interact with the internal electric fields of biological organisms to cause harm. According to this theory, very low levels of radiation have the potential to cause human harm. The theory of harm due to **** vibration has also been put forward. Nevertheless, the harm caused by thermal effects in electromagnetic radiation is still the main one.
Electromagnetic fields exist not only in a vacuum, but also in material space, including biological tissues. In the radio spectrum, the quantum energy of electromagnetic fields is so small that it is impossible to change molecular structure or break molecular bonds. At a radio frequency of 300 x 1012hz, the maximum quantum energy due to electromagnetic fields is only 1.2 mev (mega electron volt). To break the weakest hydrogen bond requires 80 mev. Therefore, radio electromagnetic waves with a frequency of 300 × 1012hz and below are called non-ionizing radiation. Ionizing radiation, such as natural nuclides' C-rays, generally have a frequency of 1012hz and a maximum energy of 2.6mev, which means that even the highest intensity non-ionizing radiation cannot produce ionization in living organisms. (Nuclear radiation, on the other hand, can produce ionization and directly destroy living organisms.) However, non-ionizing radiation produces other biological effects, such as heat, chemical reactions and the induction of electric current in the organism, etc., which can also destroy the biological organism. This is the mechanism by which electromagnetic radiation produces harm.
What is the environmental electromagnetic field
There are two categories of environmental electromagnetic fields, natural and man-made, which are an important part of the natural biosphere.
Natural electromagnetic fields include Earth, near-Earth, and cosmic causes, and are accordingly divided into the Earth's fixed magnetic field (geomagnetic field), the Earth's electric field, and the alternating electromagnetic field (EMF), which has a frequency from 103hz to 1012hz. Lightning is a type of atmospheric, or celestial, electricity. Nuclear radiation from the Earth, Sun and galaxies, on the other hand, are AC EMF sources.
Man-made electromagnetic fields are caused by human technological engineering. Their EMF radiation includes industrial frequencies and the full radio (high-frequency or RF) frequency domain. The strength of the EMF depends on the power, emission parameters and the distance from the observation point. There are also man-made electromagnetic field is divided into: industrial frequency electromagnetic field, radio frequency electromagnetic radiation field and microwave radiation field three categories, including radio broadcasting, television, microwave communications, etc. of a variety of radio-frequency equipment radiation, the impact of the region is larger.
Chinese people **** and national standards
Electromagnetic radiation protection regulations clearly stipulate the occupational exposure derived limits and public exposure derived limits, the power density of electromagnetic radiation can not exceed 20uw/square centimeter; in the living environment, the power density of electromagnetic radiation can not exceed 40uw/square centimeter. The value of electromagnetic waves is in terms of the magnetic beam density unit mg (milligauss). Household appliances, microwave ovens, vacuum cleaners, cell phones have the strongest electromagnetic radiation, are up to 200mg; (Note: 20uw / square centimeters is equal to about 2 milligauss)
Harm of electromagnetic radiation on the human body
Harm of electromagnetic radiation on the human body is multi-faceted, women and fetuses are particularly vulnerable to harm, surveys show that:
1 to 3 months for the Embryonic period, by strong electromagnetic radiation may cause limb defects or deformities;
4 to 5 months for the fetus forming period, by electromagnetic radiation may cause intellectual underdevelopment, or even cause dementia;
6 to 10 months for the fetus to grow up, by electromagnetic radiation can lead to immune function is low, the birth of weak body, poor resistance.
Research has confirmed that long-term exposure to electromagnetic radiation, electromagnetic intensity as long as 1 milligauss, can make the antibody can not be combined with blood cells, if it reaches 10 milligauss, can make the thymus cell death, immunity decline, if it reaches 40 milligauss, the embryo developmental anomalies, resulting in malformed children. For high-voltage electricity low-frequency electromagnetic wave non-free radiation general environmental recommendations for the value of 833 milligauss.
Are appliances safe?
The impact of electromagnetic waves on the human body is difficult to scientifically and meticulously to explore, because a variety of different environmental factors acting on the human body, and it is difficult to do long-term tracking survey. Whether the electromagnetic waves generated by various household appliances can cause brain cancer, leukemia, deformed babies, miscarriages and other consequences, although there are some people have opposing views, but some experts believe that this is true. And a large number of survey reports show that women are particularly sensitive, especially pregnant women. So what are some of the more "dangerous" household appliances?
Microwaves have a strong thermal effect, and microwave ovens utilize this feature of microwaves. It is in a short period of time vibration heating water molecules within the food to achieve heating, cooking purposes. Therefore it produces strong electromagnetic waves. Yanqing University research group research results show that away from the microwave oven 15cm at the magnetic field strength as low as 100mg, up to 300mg. now we know that all household appliances in the microwave oven's magnetic field is the strongest. Electromagnetic waves from microwave ovens can induce cataracts and cause brain abnormalities. According to research, microwaves also reduce fertility.
The electric mattress is a typical product of electrical products that have close contact with the body for a long time. Medical research shows that the electric mattress is in direct contact with the skin, and the cells in the resting state are exposed to electromagnetic waves for a long time, which causes health disorders in the human body. A few centimeters away from the electric mattress at the magnetic field strength of up to 20-50mg, and its electromagnetic strength also reached nearly 2kvm, and 50v high-voltage wires under the electromagnetic strength of 3kvm. strong electric field so that some people sleep after the discomfort, especially pregnant women is best to prohibit the use of electric mattresses. According to a report in 1986, the rate of miscarriage and abnormal births was higher in pregnant women who used electric mattresses than in those who did not.
The electromagnetic waves generated by TVs are similar to those generated by terminal monitors. Prolonged exposure to electromagnetic waves from terminal monitors or televisions can cause eye pain, fatigue, and other symptoms, and can lead to miscarriages, stillbirths, and births of abnormal fetuses.
With the development of electronic technology and the wider and wider application of computers, more and more people need to operate and manage computers, and deal with computers all day long, especially with food terminals, with high frequency of contact and long operating hours. China's Beijing Labor Protection Science Research Institute and a system of medical engineering research institute has repeatedly on the relevant departments of the computer radiation to carry out actual measurements. The results show that the upper part of the computer and the two sides and other parts of the standard are exceeded, generally exceeding the standard a few times to dozens of times, up to 45 times.
6 hazards of electromagnetic radiation
The International Agency for Research on Cancer (IARC), a subsidiary of the World Health Organization (WHO), has proposed that electromagnetic waves have the potential to cause cancer, requiring governments and the electric power industry should take corresponding countermeasures. China Indoor Decoration Association Indoor Environment Testing Center warns; buy housing must pay attention to the community's electromagnetic radiation pollution exceeds the standard. At present, many people have reflected their own new neighborhood electromagnetic radiation pollution is very serious, not only the home appliances are too much interference can not be used normally, and many people have different degrees of discomfort. With large-scale urban renewal and real estate development, some originally built in the city around the transmission center and high-voltage lines and other facilities around the development and construction also began, the community environment and the indoor environment in the electromagnetic radiation pollution problems also arise. Electromagnetic radiation in the end what harm to the human body? According to relevant experts, its harm is mainly six aspects.
Harm one
It is very likely to be one of the causes of leukemia in children. Medical research has proved that prolonged exposure to high electromagnetic radiation can cause changes in blood, lymph fluid and cell protoplasm. Italian experts believe that more than 400 children in the country suffer from leukemia every year, and the main reason for this is that they are too close to high-voltage lines and are thus exposed to severe electromagnetic pollution.
Hazard No. 2
Can induce cancer and accelerate the proliferation of cancer cells in the human body. Electromagnetic radiation pollution can affect the human circulatory system, immunity, reproduction and metabolic functions, serious cancer can be induced and will accelerate the proliferation of cancer cells in the human body. Swiss research data pointed out that the surrounding high-voltage lines through the household residents, the probability of suffering from breast cancer is 7.4 times higher than the average person.
The Cancer Medicine Foundation of Texas, U.S.A., for a number of patients who suffered electromagnetic radiation damage to a sample of laboratory results show that workers in the vicinity of high-voltage lines, the growth rate of cancer cells than the general population to be 24 times faster.
Third of the hazards
Impact on the human reproductive system, mainly manifested in the reduction of sperm quality in men, pregnant women have spontaneous abortions and fetal deformities, and so on.
The fourth
can lead to children's intellectual disability. According to the latest survey, China's annual birth of 20 million children, 350,000 for defective children, of which 250,000 for intellectual disability, some experts believe that electromagnetic radiation is also one of the factors affecting. The World Health Organization believes that computers, televisions, cell phones electromagnetic radiation has an adverse effect on the fetus.
Harmful fifth
Impact on people's cardiovascular system, manifested as palpitations, insomnia, some women's menstrual disorders, bradycardia, decreased blood flow, sinus irregularities, leukopenia, decreased immune function. If a patient with a pacemaker is exposed to high-voltage electromagnetic radiation, the normal use of the pacemaker will be affected.
Harmful sixth
Adverse effects on people's visual system. As the eyes belong to the human body to electromagnetic radiation sensitive organs, excessive electromagnetic radiation pollution will cause vision loss, cataracts and so on. High doses of electromagnetic radiation will also affect and destroy the body's original bioelectric current and bio-magnetic field, so that the original electromagnetic field in the body abnormal. It is worth noting that different people or the same person at different ages on the ability to withstand electromagnetic radiation is not the same, the elderly, children, pregnant women belong to the sensitive population of electromagnetic radiation.
Learn to prevent radiation
There are five kinds of people should pay special attention to electromagnetic radiation pollution: living and working in the high-voltage lines, substations, radio stations, television stations, radar stations, electromagnetic wave towers near the personnel; the frequent use of electronic instruments, medical equipment, office automation equipment personnel; living in a modernized environment, staff; wearing a pacemaker patients; living in the above environment, pregnant women, children, the elderly and pregnant women. Pregnant women, children, the elderly and patients living in the above environments. If the living environment is high in electromagnetic radiation pollution, the public must take appropriate protective measures.
Don't place household appliances too centrally, so as not to expose yourself to the hazards of overdose radiation. In particular, some easy to generate electromagnetic wave household appliances, such as radio, television, computer, refrigerator, etc. should not be centrally placed in the bedroom.
A variety of home appliances, office equipment, cell phones should try to avoid long hours of operation, while trying to avoid a variety of office and home appliances at the same time. Cell phone connection instant release of electromagnetic radiation is the largest, in the use of the head and cell phone antenna should be as far away as possible, it is best to use the separation of the headset and microphone to answer the phone.
Pay attention to the distance between the human body and office and household appliances, the use of various electrical appliances, should maintain a certain safety distance, the farther away from the appliances, the smaller the infringement of electromagnetic waves. Such as color TV and human distance should be 4 to 5 meters, and fluorescent tubes distance should be 2 to 3 meters, microwave ovens after opening to leave at least 1 meter away, pregnant women and children should try to stay away from microwave ovens.
If the housing is close to high-voltage lines, substations, radio stations, television sets, radar stations, electromagnetic wave towers, be sure to ask the experts to electromagnetic radiation testing, if the test found more than the national standard, to take timely measures.
Related experts believe that the impact of electromagnetic radiation on people, although it is prevalent, but not terrible, you can do some appropriate preventive work to reduce the direct effect of electromagnetic radiation.
