What is the harm of radiation on the human body?

How to prevent electromagnetic radiation pollution electromagnetic radiation pollution for the first time was included in the national labor protection regulations, electromagnetic radiation on the human body what harm? How to prevent? The newspaper asked experts to explain in detail □ China Consumers Association issued a daily life must prevent electromagnetic radiation consumer alert □ a variety of different frequencies of electromagnetic waves filled with space, colorless, tasteless, invisible, can penetrate any material, including the human body, the human body caused by contamination □ the elderly, children, pregnant women belong to the sensitive group of electromagnetic radiation ? News Background Recently, China Consumers' Association (CCA) issued Circular No. 9 of 2001, which is a consumer alert on the need to protect oneself from electromagnetic radiation in daily life. This warning in the consumer caused great reaction, many consumers called the China Interior Decoration Association Indoor Environment Monitoring Center for consultation. Mr. Zhan, who lives in Fangzhuang, Beijing, told the center that a few years ago, the post office of the district built an 800-megawatt microwave transmitter station in the interior of his house, which is only separated by a wall. Due to living in the environment of microwave radiation for a long time, Mr. Zhan and his beloved ones suffered from serious headache and tinnitus, etc., and as long as they left the house for a few days, the symptoms disappeared. Mr. Zhan is in contact with the center these days to discuss how to solve the problem of microwave radiation pollution at home. It is understood that a few years ago, a real estate developer in Wuhan, in a radar transmitter station opposite the proximity of an apartment building, the residents are afraid of electromagnetic radiation pollution, so far no one dares to buy to move in. It is reported that now China City Interior Decoration Association City Environmental Monitoring Center, is the city of Beijing in different areas of the city's electromagnetic radiation status of the test. What is electromagnetic radiation pollution? What are the hazards of electromagnetic radiation pollution on the human body? What are the national control standards for electromagnetic radiation? How do we prevent and reduce indoor electromagnetic radiation pollution caused by physical harm? This reporter interviewed the China Interior Decoration Association Indoor Environment Monitoring Center Director Song Guangsheng. Knowledge links Song director introduction: electromagnetic radiation pollution, also known as electronic fog pollution, high-voltage lines, substations, radio stations, television stations, radar stations, electromagnetic wave towers and electronic instruments, medical equipment, office automation equipment and microwave ovens, radios, televisions and cell phones and other household appliances work, will produce a variety of different frequencies of electromagnetic waves, these electromagnetic waves fill the space, colorless, tasteless, invisible, can be penetrated! These electromagnetic waves fill the space, are colorless, tasteless and invisible, and can penetrate any substance including human body and cause pollution to human body. Long-term exposure to more than the national regulations of the safety of the human body under the radiation dose, the body cells will be killed or killed by a large area, resulting in lesions. Domestic and foreign research on the harm of electromagnetic radiation on the human body has been carried out for many years, most scholars believe that electromagnetic radiation on the human body has the potential for harm. Director Song said that in recent years, domestic and foreign on the harm of electromagnetic radiation related reports are many, experts summarized six aspects: First, cause childhood leukemia. Long-term in the environment of high electromagnetic radiation, will make the blood, lymph fluid and cell protoplasm changes; Second, induced cancer and accelerate the proliferation of cancer cells in the human body. Electromagnetic radiation pollution affects the circulatory system, immunity, reproduction and metabolic functions of the human body, seriously inducing cancer and accelerating the proliferation of cancer cells in the human body; thirdly, it affects the human reproductive system. Thirdly, it affects the human reproductive system. The quality of male sperm decreases, and pregnant women experience spontaneous abortions and fetal malformations; fourthly, it leads to children's intellectual disability; fifthly, it affects people's cardiovascular system. Manifested as palpitations, insomnia, some women's menstrual disorders, bradycardia, decreased blood flow, sinus arrhythmia, leukopenia, decreased immune function; Sixth, on people's visual system has an adverse effect. Eyes belong to the body's sensitive organs to electromagnetic radiation, excessive electromagnetic radiation will cause vision loss, causing cataracts. Director Song especially emphasized: high doses of electromagnetic radiation will also affect and destroy the body's original bioelectricity and bio-magnetic field, so that the original electromagnetic field in the body abnormal. The elderly, children, pregnant women belong to the sensitive group of electromagnetic radiation. Expert comment Modern life has made us inseparable from electrical products, then what way to make us both enjoy high-tech to bring us the favor, but also effective prevention of electromagnetic radiation pollution? Director Song said that in recent years, the state control of electromagnetic radiation has developed a number of corresponding standards. For example, on March 11, 1988, the State Environmental Protection Bureau issued the "electromagnetic radiation protection regulations", which provides for the protection of electromagnetic radiation in the electromagnetic radiation limit range of 100KHZ-300GHZ; in 1989, "microwave radiation health standards in the workplace" was formally approved as a national standard, the limit of 0.4 milliwatts / square centimeters; approved in 1989, "the Environmental Health Standards for Electromagnetic Waves" puts forward the electromagnetic wave radiation pollution of the second level of permissible limits: the first level of standards for a safe environment, in this environment for long-term residence, work and life of all the people (including infants, pregnant women and the elderly, the sick and the disabled) of the health of the health is not subject to any impact; the second level of standards for the intermediate environment, long-term residence and life in the area of such a group of people, there may be a potentially adverse reactions to be restricted; more than Secondary standards above the environment, will bring harmful effects to the human body, the surrounding environment can only be used as green space and planting crops. The problem is that residents in the purchase of housing can not understand the status of electromagnetic radiation pollution within the living room, therefore, the experts concerned to remind the real estate developers, before the construction of the district to determine the location of the environmental index of electromagnetic radiation. So, how should we prevent and reduce electromagnetic radiation pollution in the living room? Song reminded the director of the following points: First, pay attention to the arrangement of indoor office and household appliances, do not focus on placement. Especially some easy to produce electromagnetic wave household appliances, such as radios, televisions, computers, refrigerators, etc., is not easy to focus on placement in the bedroom; Second, pay attention to the use of office and household appliances time, a variety of electrical appliances, office equipment, cell phones to avoid prolonged operation, while avoiding a variety of office and household appliances at the same time to enable. Cell phone connected to the moment of the release of electromagnetic radiation is the largest, the use of head and cell phone antenna distance away, it is best to use the separation of headphones and microphone to answer. The best computer to install lead glass made of computer radiation screen; Third, to maintain the distance between the human body and office and household appliances, color TV distance should be 4-5 meters, fluorescent lamps distance should be 2-3 meters, microwave ovens open after leaving at least 1 meter away; Fourth, living and working in the high-voltage lines, substations, radio stations, television stations, radar stations, Electromagnetic wave transmission towers near the personnel, often use electronic instruments, medical equipment, office automation equipment, living in the modern electrical automation environment of the staff, wear a pacemaker patients, living in the above environment of pregnant women, children, the elderly and the sick and other five kinds of people, we must pay special attention to the environmental index of electromagnetic radiation pollution, if the indoor environment of electromagnetic wave pollution is relatively high, must be Take appropriate measures, or ask the relevant departments to help solve the problem. In addition, Song reminded consumers to buy home appliances and office automation equipment, must buy qualified products produced by formal enterprises, because qualified products must be within the electromagnetic radiation value of the national regulations of the safety range. Science Click Electromagnetic wave pollution and its protection The wide application of electronic technology, the increasing number of household appliances, so that people are increasingly worried about the electromagnetic wave pollution generated by electrical appliances. On May 7, 1999, China's Environmental Protection Administration informed the press: electromagnetic radiation environmental pollution does exist, the country is drawing up electromagnetic radiation environmental pollution sources for environmental impact assessment. China's Environmental Protection Administration decided to establish key pollution source files and databases, to establish a sound system for approving construction projects related to electromagnetic radiation, to keep sources of electromagnetic pollution away from densely populated areas, and to incorporate the management of electromagnetic pollution into the daily track of environmental protection work. The general public only noticed the work of medium-sized and large transmitting equipment produced by electromagnetic radiation on the hazards of the person, and in fact, modern office buildings, new office equipment, household appliances in the room produced by electromagnetic radiation is more prominent. Experts call for: long hours sitting in front of the computer screen work, to take effective protective measures, the operator to wear radiation coats, vests, aprons and other series of supplies, video display terminals must be retrofitted with fluorescent screen protection network, you can also drink anti-radiation tea. In fact, electromagnetic waves are also like the atmosphere and water resources, only when people plan, use improperly when it will cause harm. A certain amount of radiation is beneficial to the human body, medical baking electricity, physical therapy and other methods are the use of the right amount of electromagnetic waves to achieve the purpose of healing and fitness. Electromagnetic radiation, we need to correctly understand, scientific protection
