1. Power plant radiation is not greater than the cell phone or even microwave ovens. If the radiation loudness, this is also true, but our home microwave oven is on 24 hours? Are our cell phones on 24 hours a day? But we live in this environment for years and years.
2. Because the harm of radiation from power plants is invisible, so you can hardly be necessarily linked to a disease or symptom to radiation, which by no means means means means that the radiation from power plants is not harmful, think about your own cell phone for more than 2 hours, you will not feel it? A lot of harm is just that we do not have the means to prove it, when the discovery of emissive substances of scientists, not also a lot of burial of their research substances, just know when it is already late.
Second. Electromagnetic radiation in the end what harm to the human body? According to relevant experts, its harm is mainly 6 aspects.
One of the hazards
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 cellular protoplasm. Italian experts have studied 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 power lines and are thus exposed to severe electromagnetic pollution.
Hazard two
Can induce cancer and accelerate the proliferation of cancer cells in the human body. Electromagnetic radiation pollution affects the human circulatory system, immunity, reproduction and metabolic functions, serious cancer can also be induced, and will accelerate the proliferation of cancer cells in the human body. Swiss research data pointed out that there are high-voltage lines around the household residents, the probability of suffering from breast cancer is 7.4 times higher than ordinary people. Cancer Foundation of Texas, the United States, for some patients who suffered electromagnetic radiation damage to do the sampling laboratory results show that in the high-voltage lines near the work of the workers, their cancer cells grow 24 times faster than the average person.
Hazard No. 3
The impact on the human reproductive system, mainly manifested in the lower quality of men's ***, pregnant women have spontaneous abortions and fetal deformities.
Harmful 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 menstrual disorders, bradycardia, decreased heartbeat blood volume, sinus arrhythmia, leukopenia, decreased immune function. If a patient with a pacemaker is in an environment of high electromagnetic radiation, it can affect the normal use of the pacemaker.
Hazard No. 6
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.
The state has a prescribed safety distance, the general distance of 15 meters or more will be fine, do not worry too much.
First of all, to make it clear that the 50 Hz industrial frequency electromagnetic oscillation of the high-voltage line can not produce radiation; only high-frequency oscillation can produce radiation. So don't worry about the effects of electromagnetic radiation. However, high voltage lines do generate industrial frequency electromagnetic fields.
High-voltage transmission lines use a three-phase system. The sum of the three-phase voltage and current is zero. If the three-phase distance is close enough, the external electric and magnetic fields are zero. But in fact, each phase of the transmission line about phase ...... >>
Question 2: Is there radiation near large substations? Does it have a big impact on people? According to the relevant provisions of the protection of electric power facilities, for a 110 kV substation transmission overhead line, it is protected by the area outside the line 10 meters range, in other words, as long as the distance from the power line 10 meters away from the place, the safety of electromagnetic radiation is guaranteed. As for 220 kV and 500 kV transmission system wires, their protection zones are 15 meters and 20 meters respectively. About the safety distance of outdoor box-type substation About the safety distance is so stipulated, 6KV safety distance is 0.7 meters, 0.4KV is the low-voltage side, do not contact on the line, the so-called safety distance is the minimum distance between the human body and the electrically charged body, I look at your picture is the substation room and the distance between the building is 0.8 meters away from the inside of the transformer is farther away from the distance in the safety of the distance is enough. But you said the electromagnetic interference to see the substation room screen wall of good, to say that the noise must have an impact. The following are other voltage levels of the safety distance for reference, unit (KV) 10KV and the following 0.7 meters, 35KV1.0 meters, 110KV 1.5 meters, 220 KV3.0 meters, 330 KV4.0 meters, 500KV 5.0 meters Substation Radiation Distance How much is the distance to recognize the impact of electromagnetic radiation on the human body, first of all, we must have a scientific and objective understanding of electromagnetic radiation. Transmission lines and substations of electromagnetic radiation belongs to the very low frequency (50HZ, also known as industrial frequency) electromagnetic radiation, and other high-frequency radiation (such as cell phones) is a different type. Moreover, the electromagnetic radiation generated in the process of power transmission will be sharply attenuated with the increase of distance. Therefore, long-term staff working in substations and power plants on duty outside the safe distance from the electric shock, health will not be affected by electromagnetic radiation. According to the national requirements, power transmission and transformation projects are through the environmental protection department of the environmental assessment and approval, to ensure that electromagnetic radiation has no adverse effects on the public High voltage lines under the ban on building, this has planning and power facilities protection of the relevant provisions of the power lines on the roof of the residential buildings are 110,000 volts of high-voltage wires, which will produce strong radiation, harmful to the human body. In addition, because the voltage is as high as 110,000 volts, and wire equipment may fail, so the building of high-voltage wires "harmful theory" and "harmless theory" of the source of foreign experts from the perspective of epidemiological investigations to conclude that "harmful"; domestic experts from the perspective of epidemiological investigations to conclude that "harmful Foreign experts from the point of view of epidemiological investigations to conclude that "harmful"; domestic experts from the point of view of electricity to conclude that "harmless". 2, high-voltage lines on who has the greatest impact on children and teenagers, the impact on the adults of the impact of small. 3, the impact of high voltage lines in the end how big? British epidemiological investigators concluded that: living in the electromagnetic radiation under the children's leukemia incidence rate of one in 700, than living in the children's incidence of electromagnetic radiation (one in 1400) than double. Conclusions of the Swedish National Board of Industrial and Technological Development: 1. Children under 15 years of age who are exposed to an average magnetic induction intensity greater than 0.2 microtesla suffer from leukemia more than 2.7 times as much as the average child; 2. 3.8 times as much if the magnetic induction is greater than 0.3 microtesla. The conclusion of the California Health Sciences Evaluation Agency: "Electromagnetic fields can lead to some degree to an increase in the risk of developing childhood leukemia, adult malignant brain tumors, amyotrophic lateral sclerosis, miscarriages, etc., and may cause suicide and adult leukemia." 4. How do high voltage lines affect people? The value of their safety indicators? High voltage lines transmit high currents, and the magnetic fields generated by high currents have an effect on human health. British experts believe that: the safety value of the magnetic field generated by high-voltage lines is 0.4 micro Tesla (μt), higher than this value, children will face the risk of disease. 5. What is the safe distance of high voltage lines? High-voltage lines of 220 kilovolts have an electromagnetic radiation intensity of more than 0.4 microtesla within a hundred meters; high-voltage lines of 132 kilovolts have an electromagnetic radiation intensity of more than 0.4 microtesla within dozens of meters; high-voltage lines of 11-66 kilovolts have an electromagnetic radiation intensity of more than 0.4 microtesla within a few dozen meters; and high-voltage lines buried in the ground have an electromagnetic radiation intensity of more than 0.4 microtesla within a few meters only. Tesla. 6, China's high-voltage line construction standards are far from being able to meet the safety requirements of China's standards: the magnetic induction intensity is less than 100 microtesla to meet the high-voltage line construction standards. 7, the impact of high-voltage lines on real estate has already appeared Homeowners have found that the impact of high-voltage lines on real estate has already begun, 1, high-voltage lines near the housing rental prices fell; 2, high-voltage lines next to the sale of second-hand houses are also affected, high-voltage lines make the hard work of a lifetime in exchange for a house facing depreciation; developers have also found that high-voltage lines near the sales of housing is not good. The safety distance from its outdoor shall not be less than 8 meters.
Question 3: Is there any radiation from the hydroelectric power plant I. Electromagnetic radiation, noise common sense
Q: What is electromagnetic radiation?
A: energy in the form of electromagnetic waves spread through space phenomenon.
Q: What are the types of electromagnetic radiation pollution sources?
A: 1, radio and television transmitting equipment, the main sectors of radio and television transmitters and relay stations around.
2, communications radar and navigation transmitting equipment communications, including short-wave transmitters, microwave communication stations, terrestrial satellite communication stations, mobile communication stations.
3, industrial, scientific research, medical high-frequency equipment.
4, electromagnetic radiation interference in transportation systems, including: electrified railroads, light rail and electrified railways, rail trams, trackless trams.
5, the power system electromagnetic radiation, high-voltage transmission lines, including overhead transmission lines and underground cables, substations, including power plants and transformer power stations.
6, household appliances electromagnetic radiation, including computers, monitors, televisions, microwave ovens, induction cookers, wireless phones, cell phones and so on.
Q: electromagnetic radiation affects the human body mechanism is mainly what?
A: Now most people know that the hospital X-ray can not be photographed too often, the reason is that frequent X-ray radiation may have a cumulative effect on health hazards. Similarly, the human body to receive electromagnetic radiation is too strong, too long or too close, may also cause harm, its role in the human body is mainly thermal, non-thermal and cumulative effects.
(1) thermal effect More than 70% of the human body is water, water molecules are subject to electromagnetic radiation friction, causing the body to warm up, thus affecting the normal work of the body organs.
Domestic and foreign research has confirmed that the role of electromagnetic radiation on the human body is mainly thermal effect, the harm is mainly in the radio frequency electromagnetic field. Substation radiation belongs to the industrial frequency electromagnetic field, rather than radio frequency electromagnetic field. When the field strength of radio frequency electromagnetic field reaches a certain value, in order to have an effect on the human body. Under the action of radio frequency, the human body absorbs electromagnetic radiation energy, its energy will be converted into heat. Only when more than the ability to regulate body temperature, only when the temperature balance dysfunction, resulting in increased body temperature, thus producing physiological dysfunction and pathological changes and other biological effects.
(2) non-thermal effects of human organs and tissues are weak electromagnetic fields, they are stable and orderly, once the interference of external electromagnetic fields, in a state of equilibrium of the weak electromagnetic field will soon be destroyed, the human body will also suffer damage.
(3) Cumulative effect Thermal and non-thermal effects on the human body, the damage to the human body has not yet had time to repair itself before (usually referred to as the human body's tolerance - internal resistance), and then again subjected to electromagnetic radiation, the extent of the damage will occur cumulatively, and in the long term, will become permanently sick.
Q: What is the role of electromagnetic radiation?
A: Electromagnetic radiation can be described as a magical power, in many places can see its figure. Specific applications are:
(1) medical applications: microwave physiotherapy blood, treatment of tumors, etc.
Treatment of tumors, antennas or radiators can control the temperature in a very narrow range of temperatures that only kill cancer cells. Electromagnetic radiation thermotherapy uses electromagnetic energy to warm up local tissues, improve blood circulation, promote metabolism and achieve the purpose of treatment.
(2) Transmission of information: communication, radio, television, etc.
Communication is mainly microwave communication and long and short-wave communication, such as cell phones, satellite phones. There is also the use of long and short-wave communication, such as walkie-talkies. Broadcasting is to turn the sound into electric current, and then through the transmitting antenna to spread out in the form of waves.
(3) target detection: radar, navigation, remote sensing, etc.
The principle of radar is the transmitter to detect the target to send a pulse wave, the pulse wave encountered by the detection of the target can be reflected back, and then you can measure the reflected wave and the time interval between the transmitter, so as to know the detection of the target and the radar is located in the distance.
(4) Induction heating: induction furnace, high-frequency quenching, high-frequency melting, high-frequency welding, high-frequency cutting, etc.
The use of high-frequency electromagnetic energy in the medium- and long-wavelength bands to make the conductor or the semiconductor itself heats up, to achieve the purpose of thermal processing.
(5) medium heating: microwave ovens, microwave dryers, plastic heaters, etc.
The non-conductor placed in a strong electromagnetic field, its positively and negatively charged molecules or atoms in the alternating electromagnetic field, under the action of the electric field frequency oscillation, "friction" caused by the heat, to achieve the purpose of processing.
(6) military applications: electronic warfare, electromagnetic weapons, etc.
Such as the Gulf War, the U.S. first identified the Iraqi army to use the signal frequency, and then use the same frequency to send out signals with stronger power, resulting in Iraq
Q: What is the principle of operation of electromagnetic shielding devices? What are the main electromagnetic radiation protection products?
Electromagnetic shielding device is generally a closed shell made of metal materials. When the electromagnetic field is transmitted to the gold ...... >>
Question 4: Is there much radiation in thermal power plants? As the radiation itself has a variety of different frequencies of different strengths of radiation will have a different response, as of now, no one dares to say that as long as the radiation is as low as how much is safe. And because each person's body resistance is different, each person will appear different degrees of symptoms. Generally, exposure to electromagnetic radiation can cause headaches, insomnia, irregular heart rate and other central nervous system problems. At the same time, for some people's eyes may have an impact on the vision loss, skin diseases and other phenomena, and in some cases may cause cancer. Children and the elderly are generally less resistant to radiation, so it is more harmful to the elderly and children. From my personal experience, if you work in a power plant for a day, you will obviously have a feeling of dizziness, at first I thought it was a psychological illusion, but later realized that it is not. And many people see the power plant radiation harmless claims, often the following:
1. Power plant radiation is not greater than the cell phone or even microwave ovens. If the radiation from the loudness, this is also true, but our home microwave oven is on 24 hours a day? Are our cell phones on 24 hours a day? But if you are a directly engaged in the operation of the power plant staff, then the day will be at least 8 ~ ~ 9 hours of direct radiation!
2. There is no evidence that radiation from power plants affects health. Maybe someone will say you are worrying about the sky, but because the harm of radiation is invisible, so it is difficult to link your inevitable to a disease or symptoms to radiation, which by no means means means that the radiation of the power plant is not harmful, think about their own cell phone to play more than 2 hours, will not feel it? A lot of harm just we do not have the means to prove it, when the discovery of emissive substances of scientists, not also many buried in their research substances, just know when it is already late.
Second. Electromagnetic radiation in the end what harm to the human body? According to relevant experts, the harm is mainly six aspects.
One of the hazards
It is very likely to be one of the causes of leukemia in children. Medical research has proved that prolonged exposure to high levels of electromagnetic radiation can cause changes in blood, lymph fluid and cellular protoplasm. Italian experts believe that more than 400 children in that country suffer from leukemia every year, mainly due to the proximity of high-voltage power lines, and thus exposed to severe electromagnetic pollution.
Hazard No. 2
The ability to induce cancer and accelerate the proliferation of cancer cells in the human body. Electromagnetic radiation pollution affects the human circulatory system, immune, reproductive and metabolic functions, and in severe cases can induce cancer and accelerate the proliferation of cancer cells in the human body. According to a Swiss study, residents of households surrounded by high-voltage lines are 7.4 times more likely to develop breast cancer than the general population. The Texas Cancer Medical Foundation for some patients who suffered electromagnetic radiation damage to do sampling laboratory results show that in the high-voltage lines near the work of workers, their cancer cells grow 24 times faster than the average person.
Hazard No. 3
Affects the human reproductive system, mainly manifested in the lowering of men's *** quality, and the occurrence of spontaneous abortions and fetal malformations in pregnant women.
The fourth
can lead to children's intellectual disability. According to the latest survey, China's annual birth of 20 million children, there are 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 a negative impact on the fetus.
Hazard No. 5
The impact of people's cardiovascular system, manifested in palpitations, insomnia, some women's menstrual disorders, bradycardia, decreased cardiac blood volume, sinus arrhythmia, leukocyte reduction, decreased immune function. If patients with pacemakers are exposed to high levels of electromagnetic radiation, the normal use of the pacemaker may be impaired.
Hazard #6
Adverse effects on the visual system. Because 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 also affects and destroys 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 group of electromagnetic radiation.
In view of this, I suggest that in the power plant engaged in the operation or maintenance of friends to pay attention to their own health, to take appropriate protective measures to protect their right to life and health! !... >>
Question 5: Is there radiation from solar power stations In fact, not only is there electricity, there is radiation, in fact, every thing around us is radiated, the simplest is thermal radiation. But then, within a certain range of radiation is not going to have an impact on the human body. For example, photovoltaic power plant radiation, in fact, with ordinary household appliances about the same. Otherwise the state would not be so pushing this one. (Professional manufacturers, professional design and installation. Guangdong De nine professional for you to answer)
Question six: thermal power plants have no radiation pollution thermal power plant radiation pollution should not.
If you say that the radiation is certainly there, sunlight is a light radiation. The first thing you need to do is to get a good deal on the price of the product, and then you need to get a good deal on the price of the product.
Our use of television sets, cell phones and other electronic products have a certain radiation.
Ceramics, and so on have a certain amount of radiation.
But this radiation has no effect on the human body, so it is not called pollution.
Question 7: Are power plants harmful to the body? What harm? Because the radiation itself has a variety of different frequencies of different strengths of radiation will have a different response, as of now, no one dares to say that as long as the radiation is as low as how much is safe. And because each person's body resistance is different, each person will appear different degrees of symptoms. Generally, exposure to electromagnetic radiation can cause headaches, insomnia, irregular heart rate and other central nervous system problems. At the same time, for some people's eyes may have an impact on the vision loss, skin diseases and other phenomena, and in some cases may cause cancer. And children and the elderly resistance to radiation is generally worse, so the harm to the elderly and children is also greater. Electromagnetic radiation in the end what harm to the human body? According to relevant experts, the harm is mainly six aspects: one of the hazards It is very likely to cause children to suffer from one of the causes of leukemia. Medical research has proved that long-term in the environment of high electromagnetic radiation, will make the blood, lymph fluid and cell protoplasm changes. Italian experts believe that more than 400 children in that country suffer from leukemia every year, the main reason is that it is too close to high-voltage power lines, and thus subject to serious electromagnetic pollution. Harmful two can induce 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, and in serious cases it can induce cancer and accelerate the proliferation of cancer cells in the human body. Swiss research data pointed out that there are high voltage lines around the residents of households, the probability of developing breast cancer is 7.4 times higher than that of the general population. Cancer Medical Foundation of Texas, the United States of America for some patients who suffered electromagnetic radiation damage to do the sampling results show that in the high-voltage lines near the work of workers, its cancer cells grow 24 times faster than the general population. Hazard No. 3 affects the human reproductive system, which is mainly manifested in the lowering of men's *** quality and the occurrence of spontaneous abortion and fetal malformation in pregnant women. Harmful four can lead to children's intellectual disability. According to the latest survey, China's annual birth of 20 million children, there are 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 a negative impact on the fetus. Harmful fifth affect people's cardiovascular system, manifested as palpitations, insomnia, some women's menstrual disorders, bradycardia, decreased blood flow, sinus arrhythmia, leukocyte reduction, decreased immune function. If patients with pacemakers are exposed to high electromagnetic radiation, it will affect the normal use of pacemakers. Hazard No.6 Adverse effect on people's visual system. Because the eyes belong to the human body to electromagnetic radiation sensitive organs, too high electromagnetic radiation pollution will cause vision loss, cataracts and so on. High doses of electromagnetic radiation also affects and destroys 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.
Question 8: Is solar power station radiation on the human body Photovoltaic power generation is the direct conversion of light energy into electricity, which does not have any chemical changes as well as nuclear reactions
So photovoltaic power generation is not short-wave radiation.
To be clear, the meaning of radiation is very broad, light is radiation, electromagnetic waves are radiation, particle flow is radiation, heat is also radiation, so clearly we are in a variety of radiation.
The term "radiation" is generally used to refer to radiation that is harmful to human cells, such as those that cause cancer, and those that have a high probability of causing genetic mutations. In general, this includes short-wave radiation and some high-energy particle streams.
For photovoltaic power generation, the generator theory is completely direct energy conversion, the process does not have any other products generated, so there will be no additional radiation.
Question 9: Will there be radiation next to the generator Radiation from high-voltage power lines can be very harmful One of the most likely causes of leukemia in children. Medical research has proved that long-term exposure to high electromagnetic radiation in the environment, will make the blood, lymph fluid and cell protoplasm changes. Italian experts believe that more than 400 children in that country suffer from leukemia every year, the main reason is that they are too close to high-voltage power lines, and are thus exposed to serious electromagnetic pollution. Hazard No. 2: The ability to induce cancer and accelerate the proliferation of cancer cells in the human body. Electromagnetic radiation pollution affects the circulatory, immune, reproductive and metabolic functions of the human body, and in severe cases can induce cancer and accelerate the proliferation of cancer cells in the human body. According to a Swiss study, residents of households surrounded by high-voltage lines are 7.4 times more likely to develop breast cancer than the general population. Cancer Medical Foundation of Texas, the United States of America for some of the electromagnetic radiation damage to the patient's sample of laboratory results show that in the high-voltage lines near the work of workers, their cancer cells grow 24 times faster than the general population. Hazard No. 3 affects the human reproductive system, which is mainly manifested in the lowering of men's *** quality and the occurrence of spontaneous abortion and fetal malformation in pregnant women. Harmful four 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 a negative impact on the fetus. The fifth harm affects people's cardiovascular system, manifested as palpitations, insomnia, some women's menstrual disorders, bradycardia, cardiac blood volume reduction, sinus arrhythmia, leukocyte reduction, decreased immune function. If patients with pacemakers are exposed to high electromagnetic radiation, it will affect the normal use of pacemakers. Hazard No.6 Adverse effect on people's visual system. Since the eyes are sensitive organs to electromagnetic radiation, excessive electromagnetic radiation pollution will cause vision loss, cataracts, etc.. High doses of electromagnetic radiation also affects and destroys 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 group of electromagnetic radiation.
Question 10: living in the vicinity of the substation is harmful to the body? Radiation? What is the impact? I don't want to go into a long story, simply say that high-voltage radiation is not a small harm.
The International Health Organization (WHO) has confirmed that high voltage power transmission generated by the industrial frequency electromagnetic field is a suspected human carcinogen. Numerous studies have also demonstrated the correlation between IEMF and a number of other human diseases, such as neurological disorders. Residents, especially children and the elderly, are more sensitive and vulnerable to IEMF. Scientific studies have also shown that the chances of people suffering from leukemia and cancer in the range of 40 meters - 300 meters around 220KV high-voltage lines are several times higher than in other areas, and that electromagnetic radiation can also lead to miscarriages in pregnant women, fetal malformations and cardiovascular diseases, which are extremely harmful to human beings
You can go to your local civil affairs bureau to reflect on this. Grab a hold of it
