subject: Review Of Electromagnetic Radiation Hazards Appliances - Household Appliances, Electromagnetic [print this page] With communications and electronics industry, modern people enjoy the convenience of modern communications equipment and electrical appliances brought comfort, but also by more and more from a variety of electrical and communications equipment radiation, people increasingly exposed to electromagnetic radiation in a growing environment, the usual routine of home appliances have also been accused of indoor electromagnetic radiation is an invisible killer, and domestic appliances how much electromagnetic radiation hazards, what kind of attitude should be adopted to evaluate and use ordinary household appliances household appliances more and more consumer attention.
What is electromagnetic radiation
We usually use the electrical and communications equipment, such as television, mobile phones in use changes in electric and magnetic fields produce electromagnetic interaction, electromagnetic propagation of electromagnetic energy also have to spread this energy to the form of electromagnetic waves transmitted through space phenomena as electromagnetic radiation. Electromagnetic radiation has become the current water, air and noise pollution after the fourth-largest, and has been included in the UN Conference on the Human Environment to control pollution.
Although appliances have varying degrees of electromagnetic radiation released, but what the human body can produce much harm, but also a lack of accurate experimental basis, the general view is that electromagnetic fields can interfere with cellular calcium release and absorption rate , leading to cancer formation, while low-frequency radiation in human cancers, reproductive diseases, genetic disorder, senile dementia, amnesia for important reasons, and electromagnetic radiation hazards to children the most, long-term exposure to electromagnetic radiation in children, the cancer will increase probability.
The radiation intensity of common household electrical appliances
Current international and domestic institutions have specialized conducting related research and testing, according to the World Health Organization data, we can understand the public's daily use of household appliances and electromagnetic field strength.
Note: ICNIRP (International Commission on Non-Ionizing Radiation Protection) public exposure limit recommended by 5kV / m (frequency electric field).

From the above data, the appliances we use every day, mainly in power-frequency magnetic radiation exceeded, and mainly in the hair dryer, vacuum cleaners, electric shavers, fluorescent lights and microwave ovens on. Very often, you may also use several appliances in use during the magnetic field strength is also accumulate there. In some informal tests, many people find that there is the phenomenon of radiation group, "'group radiation' cause radiation over a wide frequency band, will increase the resonance between devices and the superposition of radiation energy. When the energy reaches a certain degree, will the human body with a combination of thermal effects induced by radiation (the higher the frequency the more severe), non-thermal effect (full band) and the resonance effect (when the wavelength is proportional to the time scale of organisms). "This also illustrates the effects of radiation than people more widely understood.
Scientific use of electrical and electromagnetic radiation
Present, the domestic appliance products for the electromagnetic radiation has no specific criteria, usually with internationally accepted standards, the product does not have the appropriate product labeling and used to explain the radiation levels, and when purchasing products products can not compare and judge the degree of radiation, the absence of such information, consumers lack a sufficient understanding of the product and can not make the normal in-use protection and to avoid radiation.
Radiation damage to household electrical appliances, from the current academic session of the domestic public opinion point of view and media view, both completely different attitude. At present, many media articles are also on the electromagnetic radiation as a general explanation on home appliances such as cooker, microwave ovens and other products produced by the radiation that is relatively weak radiation, such radiation is far less than cell phone radiation and other communications equipment, can rest assured that use. From the academic session of the general point of view, long-term low doses of electromagnetic radiation exposure likely to cause health hazards, compared with foreign European and American countries, China's population more than housing, and the actual public acceptance of the electromagnetic radiation exposure levels higher than in Europe and the United States. Although experts from the academic point of view that the objective of low doses of radiation hazards exist, they recommend that everyone with a relaxed attitude to deal with electrical radiation, a scientific point of view
Use of electrical appliances to avoid the radiation.
Electromagnetic radiation mainly by the electric motor in the coil and produced, decreasing exponentially with increasing distance, so the best way is to use radiation from electrical appliances, while avoiding the concentration of appliances placed. Special attention to the crowd when the use of household appliances with radiation facilities, and children away from electrical appliances as possible.
