High-voltage line board of medical equipment

High-voltage lines will do, because the voltage is very high, and the current passing through people is also very large, forming an electric shock.

The cuticle of a bird's claw is very thick, but it is actually insulated and won't get an electric shock.

A popular science article: electromagnetic radiation pollution should not be underestimated. Most scholars at home and abroad believe that electromagnetic radiation is potentially dangerous to human body. Mainly manifested in the following aspects-it will lead to leukemia in children. Medical research has proved that long-term exposure to high electromagnetic radiation will change blood, lymph and cell protoplasm. It can induce cancer and accelerate the proliferation of cancer cells in human body. Electromagnetic radiation pollution will affect the circulatory system, immunity, reproduction and metabolic functions of human body, and even induce cancer in severe cases, accelerating the proliferation of cancer cells in human body. Swiss research data show that the probability of breast cancer among residents with high-voltage lines passing around is 7.4 times that of ordinary people. Will affect people's reproductive system. The main manifestations are the decline of male sperm quality, spontaneous abortion of pregnant women and fetal malformation. Will lead to mental retardation in children. The World Health Organization believes that the electromagnetic radiation from computers, televisions and mobile phones has a negative impact on the fetus. Affect people's cardiovascular system. The main manifestations are palpitation, insomnia, menstrual disorder in some women, bradycardia, decreased cardiac output, irregular sinus heart rate, leukopenia and decreased immune function. It has a bad influence on people's visual system. Mainly manifested as decreased vision, causing cataracts and so on. Experts pointed out that there are five kinds of people who should pay special attention to electromagnetic radiation: first, people who live and work near high-voltage lines, substations, radio stations, TV stations, radar stations and electromagnetic wave towers; Second, people who often use electronic instruments, medical equipment and office automation equipment; The third is the employees living in the modern electrical automation environment; Fourth, patients wearing pacemakers; Fifth, pregnant women, children, the elderly and patients living in the above environment. There are many ways to prevent pollution. First, pay attention to the setting of indoor office and household appliances. Don't put household appliances too concentrated, lest you be exposed to the danger of excessive radiation. In particular, some household appliances that are prone to electromagnetic waves, such as radios, televisions, computers, refrigerators and other electrical appliances, are not suitable for centralized display. Second, pay attention to the use time of office and household appliances. All kinds of household appliances, office equipment, mobile phones, etc. Long-term use should be avoided, and all kinds of office and household appliances should be avoided at the same time. When using a mobile phone, try to keep the distance between the head and the antenna of the mobile phone, and it is best to use a separate earphone and microphone to answer the phone. Third, pay attention to the distance between human body and office and household appliances. The use of all kinds of electrical appliances should keep a safe distance. The farther away from the electrical appliance, the less electromagnetic wave will harm. 4. If the house is close to high-voltage lines, substations, radio stations, TV stations, radar stations and electromagnetic wave transmission towers, experts should be invited to conduct electromagnetic radiation detection. If it is found that it exceeds the standard, measures should be taken in time. Staying under high-voltage lines for a long time is easy to cause cancer. The Swedish National Council for Industry and Technology Development is now convinced that power frequency AC radiation from high-voltage lines (mainly below 220 kV) will lead to childhood leukemia. Studies have shown that some cancers, especially childhood cancers, do come from high-voltage transmission lines around the living environment. They also selected the areas along the line under the 220kV-400kV high-voltage power grid for investigation, and found that during the period of 1960- 1985, there were indeed 500,000 people living within 300m of the power line, 142 children were sick and 39 people suffered from leukemia. They also obtained the following data through further calculation: if children below 15 are exposed to an environment with an average magnetic induction intensity greater than 0.2, the probability of leukemia is more than 2.7 times that of ordinary children, and if the magnetic induction intensity is greater than 0.3, the probability of leukemia is 3.8 times that of ordinary children. In addition, American scholars have also conducted relevant investigations before, and concluded that the rate of children living near high-voltage lines suffering from nervous system cancer and leukemia is 2-3 times higher than that of ordinary children. Therefore, especially pregnant women and children should pay special attention not to stay near high-voltage lines below 220 kV for too long.
