National standards of the People's Republic of China:The electromagnetic radiation protection regulations specify that occupational exposure limits and public exposure limits are specified, and the power density of electromagnetic radiation cannot exceed 20uW/ cm2. In the living environment, the power density of electromagnetic radiation cannot exceed 40uW/ cm2. The value of electromagnetic waves is measured by the magnetic beam density unit MG (milligauss). In the household appliance, microwave oven, vacuum cleaner, mobile phone electromagnetic radiation is the strongest, can reach 200 mg (200 milligauss); (note: 20uW/ m2 is approximately 2 milligauss)
European standard：Switzerland requires that within 2 meters of electrical appliances, it is safe within 2 milligauss. The human body can only withstand 2 milligauss radiation effects, 2 meters is 2 meters.
All kinds of household electrical appliances measured electromagnetic radiation data.
Learn to guard against radiation：Mention "electromagnetic radiation" 4 words, many people will feel inexplicable panic, some media even portray it as a stealth killer. Is electromagnetic radiation really so terrible? In fact this is a misunderstanding, all electrical appliances electromagnetic radiation, electromagnetic radiation is everywhere, has been with us "shadow", only when it exceeds a certain limit pollution, negative effects will gradually appear. But it is possible to avoid damage to our bodies by staying away from the sources of electromagnetic radiation. The distance between the human body and the office and household electrical appliances, the use of all kinds of electrical appliances, should maintain a certain safe distance, the farther away from the electrical appliances, the less vulnerable to electromagnetic waves. Such as color television and the distance of people should be in 2 to 3 meters, and fluorescent tube distance should be in 2 to 3 meters, microwave oven after open to leave at least 1 meter far, pregnant women and children should as far as possible away from the oven, should not be more centrally in the bedroom.
Electromagnetic radiation 6 hazard：The international cancer research organization, which is part of the world health organization, argues that electromagnetic waves have the potential to cause cancer and require governments and the power industry to respond accordingly. China interior decoration association indoor environment testing center warning; Buy a house must pay attention to the electromagnetic radiation pollution of the residential area exceeds standard. There are many citizens reflect their electromagnetic radiation pollution is very serious, building a village home appliances are not only too much interference can't normal use, and many people appear different degree of symptoms. As large-scale city real estate development and transformation, some original transmission launch center was built in the cities and also began to develop around the high tension line facilities construction, environment and interior environment of electromagnetic radiation pollution problems will follow. What harm does electromagnetic radiation have to the human body after all? According to the experts, there are six main hazards.
One of the hazardsIt is probably one of the causes of leukemia in children. Medical research has shown that long-term exposure to high electromagnetic radiation changes blood, lymph, and protoplasm. Italian experts said that more than 400 children in the country suffer from leukemia each year, mainly because they are too close to the high pressure line and are therefore severely contaminated by electromagnetic radiation.
The second damageIt can induce cancer and accelerate the proliferation of cancer cells in the human body. Electromagnetic radiation pollution affects human circulatory system, immunity, reproduction and metabolic function, and it can also induce cancer and accelerate the proliferation of cancer cells in the human body. The Swiss study found that residents with high pressure lines were 7.4 times more likely to develop breast cancer. Texas cancer medicine foundation research in some patients suffer from electromagnetic radiation damage of sampling test results show that near the high tension line workers, the cancer cell growth speed to 24 times faster than the average person.
Harm to a thirdThe main effect of human reproductive system is the decrease of sperm quality, spontaneous abortion and fetal malformation.
Of the fourIt can lead to intellectual disability in children. According to a new survey, 350,000 of the 20 million children born in China each year are defective, of which 250,000 are mentally disabled, and some experts believe that electromagnetic radiation is also a factor. The world health organization believes that the electromagnetic radiation from computers, television sets and mobile phones has an adverse effect on fetuses.
Of the fiveInfluence people's cardiovascular system, show the palpitation, insomnia, part of the female menstrual disorder, bradycardia, cardiac blood volume reduction, sinus, irregular heartbeat, leucopenia and immune function decline, etc. If a patient with a pacemaker is in the environment of high pressure electromagnetic radiation, it will affect the normal use of pacemaker.
Of the sixIt has bad effects on people's visual system. Because the eye belongs to the human body to electromagnetic radiation sensitive organ, excessive electromagnetic radiation pollution can cause vision decline, cataract and so on. High doses of electromagnetic radiation can also affect and destroy the original biological current and biological magnetic field in the human body, causing abnormal electromagnetic fields in the body. It is worth noting that different people or the same person have different ability to bear electromagnetic radiation at different ages. The elderly, children and pregnant women are sensitive to electromagnetic radiation.
