People who work, study and live in an environment with concentrated radiation sources are prone to insomnia, dreaminess, memory loss, physical weakness and low immunity, and their cancer cells grow 24 times faster than normal people. How far is the radiation from us? In our living environment, radiation is everywhere! Household appliances: TV, refrigerator, air conditioner, microwave oven, vacuum cleaner and other office equipment: mobile phones, computers, photocopiers, electronic instruments, medical devices and other home improvement: marble, composite floor, wall wallpaper, paint and other surrounding environments: high-voltage lines, substations, TV (radio) signal towers and other natural environments: a healthy sunspot can withstand a short load of 5000R, but only 700R, generally. At the same time, it may affect some people's eyes, such as decreased vision, skin diseases and even cancer. For pregnant women who may cause miscarriage, the elderly who have installed pacemakers should pay special attention. At the same time, different people or the same person have different tolerance to electromagnetic radiation at different ages. Even in an environment exceeding the standard, it does not mean that everyone will get sick, so there is no need to "be a soldier" for electromagnetic radiation. However, preventive measures should be taken for the elderly, children, pregnant women or patients with pacemakers, people who are sensitive to electromagnetic radiation, and people who work in excessive electromagnetic radiation for a long time. With the rapid development of science and technology, various scientific and technological products and household appliances have entered people's lives, which have greatly improved people's work efficiency and improved people's lives. I can't imagine what people's life would be like without these live broadcast devices. However, with more and more high-voltage electricity and transmission towers around the city, there are more and more electrical equipment at home, which makes people feel convenient and hurt at the same time. At present, electromagnetic radiation pollution has become the fourth largest environmental pollution after water, air and noise. What would you do if one day, the house you live in was suddenly told that it was in serious electromagnetic radiation? Among the many household appliances, can you find out which ones have higher radiation? What is electromagnetic radiation? From a professional point of view, electromagnetic radiation is a phenomenon that energy propagates through space in the form of electromagnetic waves. Almost any electrical appliance in our home will produce electromagnetic radiation. Such as microwave oven, TV, computer, mobile phone and so on! Protective clothing: including coats, vests, aprons and maternity clothes. Made of special fiber, it has good anti-electromagnetic radiation and anti-static effect. Especially for families with microwave ovens, it is best to equip them with protective aprons, which can effectively prevent electromagnetic radiation. For pregnant women, if they come into contact with electrical equipment, they must wear protective Chinese-style chest covering or protective clothing to ensure the healthy growth of the fetus. Radiation shielding: it has many functions such as radiation protection, anti-static, anti-glare and so on, and it also plays a certain role in protecting eyesight. Another way is to pay attention to time and distance or eye drops. The degree of injury is proportional to time, that is to say, the longer the exposure to electromagnetic radiation, the greater the injury. Is inversely proportional to the distance, the distance is ten times larger, the radiation is one percent of the original, the distance is one hundred times larger, and the radiation is one ten thousandth. Q&A Editor: What's the difference between electromagnetic radiation and electromagnetic radiation pollution? Q: Actually, electromagnetic radiation and electromagnetic radiation pollution are two concepts. Any charged body has electromagnetic radiation. When the intensity of electromagnetic radiation exceeds the national standard, it will have negative effects and cause different diseases and harms to the human body. This part of radiation that exceeds the standard electromagnetic field strength is called electromagnetic radiation pollution. A: What's the effect of mobile phone base station radiation on people's health? Q: This is a common phenomenon. Many residential buildings in the city have installed mobile phone base stations. Some citizens are worried about whether the electromagnetic radiation generated by this equipment will cause harm to the human body. In fact, there is no need to worry about this problem. The difference between cell phone radiation and cell phone base station radiation. Generally, the electromagnetic radiation value of mobile phone is between 0.03 and 0.7, while the radiation value of mobile phone base station is 10 microwatt. The radiation value generated by the mobile phone base station is not much higher than that of the mobile phone! In addition, the closer the electromagnetic radiation, the longer the radiation time and the deeper the damage! Moreover, the distance between the mobile phone base station installed on the roof of our general residents' home and us is a safe distance, so don't worry! Edit specific electrical equipment protection in the home. The electric radiation index of this paragraph is divided into five points. Anyone who is rated as five points is seriously exceeding the standard and should attract your attention; Samsung and above also belong to the over-standard range, which should also attract your attention; One star is safe and can be used with confidence. There are two levels of electromagnetic radiation, among which the unit of power frequency band is μT, and the radiation above 0.4μT belongs to strong radiation, which is harmful to human body and prone to leukemia after long-term contact. If the radiation is below 0.4μT, it is relatively safe. The unit of radio frequency electromagnetic wave is μW/㎝2. 1. TV traditional cathode ray tube TV cathode ray tube was the first to be tested. First, we test it at close range. Within the first half of a meter, the radiation value generated during normal startup is 0. 12μT, 0.30μT during normal viewing, 0.27μT during channel changing, 0.1/μ t during standby, and the radiation value on the side is 0.0 during normal viewing. Because most people watch TV at a distance of about 3 meters, we also made a test on the front 3 meters, and found that the radiation has a great degree of attenuation: the startup, normal viewing, channel changing and standby state are all 0. 12μT, and the test results show that the normal viewing of traditional CRT TV will not cause harm. But to our surprise, the radiation intensity behind it is relatively high, and the radiation value reaches 4.8μT within half a meter after starting the machine, and the radiation through glass and wooden boards has not decreased, even through the wall with a thickness of 10 cm, the radiation value is 0.9 μ t. Please be careful if the back of your TV is facing the bedside of your bedroom. But usually people have different time to rest and watch TV, so it is not a big problem. Look at the plasma TV again, the front is half a meter, the starting, watching and channel changing are 0. 1 1μT, the standby is 0. 12μT, and the side is 0.11μ t; The front is 3 meters, and the TV is 0. 12μT when turned on, 0. 14μT when viewed normally, and 0. 1 1μT when turned on or on standby. According to the test results, the radiation intensity of plasma is less than that of traditional TV. When the rear projection TV is viewed normally, it is 0. 12μT, 0. 19μT and 0. 14μ t near the front, side and back of the fuselage, respectively. First half meter 0.11μ t; 3 meters ahead is 0.1μ t. The most reassuring thing in TV series is LCD TV. No matter whether the front is half a meter or three meters, the instantaneous test results at startup, normal viewing, channel changing and standby state are all 0. 1μT, while the side is only 0. 1 1μT, and basically the radiation intensity has not changed. Test results: Comparing the three kinds of TVs, we can easily find that LCD TV and rear projection TV have the smallest radiation, plasma TV has a little stronger radiation, and CRT TV is bigger, but it is mainly behind TV. It is recommended that you keep a certain distance when watching, especially for children. 2. DVD player and home theater The popular home theater in recent years, that is, DVD player plus sound system, is closely related to the test results. DVD 1.2μT, OK player 1.2μT, power amplifier 1.24μT, small speaker 1.5μT, large speaker 0.49 μ t, if turned on at the same time, can it radiate? Tip: I suggest you use home theater as little as possible. If you want to sing, you'd better go to KTV. CRT monitors, liquid crystal displays, desktop computers, large computers, small speakers, and notebook computers are always considered to have large radiation. Is that what everyone thinks? We tested it first. The front of the display is close to 1.00μT, and the side of the display is close to 0.55μT, which is not small! Look at the center of the display screen, the distance is 0.03 meters, and the radiation is still 0.55 μ t. Is this CRT monitor really as big as we thought? To further confirm, we began to look for its safe distance. In this way, when the distance is 0.2 meters, the radiation in front of the display screen will be attenuated to 0.18 μ t, and it seems that the CRT display can be used safely as long as the distance is 0.2 meters. Some viewers asked if it was as big as CRT TV, and it was not big after the test. Some people like to use radiation screensavers, so is it effective? We also specially tested it, and the screensaver radiation only decreased by 10%. Screen saver doesn't seem to have much effect. Radiation index of CRT monitor: ★★ It seems that LCD is really reassuring. Radiation index of LCD: ★ The back is 0.46μT, but we are usually at a certain distance from the back of the host, so the impact is not great. Also, the startup moment and standby state are both 0.17 μ t, and one more thing to say is that if the power connection of the desktop computer is reconnected, the radiation is 0.47μT, so keep a distance when using the desktop computer again. The radiation index of the desktop computer host: ★★★☆☆☆ However, the next test is not very optimistic. Subwoofer speaker, center of operation panel, 0.03m away, 0.63μ t; The center of the right side of the speaker is 0.03m and 5.68 μ t away; Radiation is not small, so what is its safe distance? After careful testing, it is found that when the distance is 0.4 meters, its radiation is reduced to 0. 17μT ... So the subwoofer speaker has serious radiation, and it should be kept at least half a meter away when using it. Radiation index of subwoofer speaker: ★★★★☆ Finally, notebook computer, 0. 1m 0. 13μT in front of display screen, 0.3m 0. 10μT in front of display screen, 0.3m 0. 13μT on display screen side and 0./kloc above keyboard. The test results show that the radiation of notebook keyboard is slightly stronger and the power adapter is the largest. Notebook radiation index: ★☆☆☆☆☆ Tip: LCD screen radiation is very small, CRT monitor is slightly larger, but they are all within the safe range; The radiation on the back and side of the host is large, so it is strongly recommended that you do not open the chassis for the convenience of heat dissipation. The subwoofer has serious radiation, so keep a distance of at least half a meter when using it. The radiation of the notebook is concentrated above the keyboard, so keep a distance from the power adapter when using the notebook. Oh, by the way, it is said that this computer and notebook don't radiate much, but the photoelectric mouse turns red and blue, which is scary. Is there radiation? Are the radiation of wireless mouse and keyboard less than that of ordinary ones? And that WLAN transmitter! There are digital devices, digital cameras, MP3 and MP4. To tell you the truth, this battery-powered DC appliance is the safest. Ordinary mouse: 0. 1μT Ordinary keyboard: 0. 1 1μT Wireless mouse: 0.53μT (above the mouse) Wireless keyboard: 0.96μT (above the keyboard) Wireless gateway: 0. 15μT (above the gateway) Printer. 5438+0μT MP4 power adapter: 0. 16μT power adapter for ordinary mouse, keyboard, wireless gateway, printer, digital camera and MP4: ★☆☆☆☆☆; Radiation index of wireless mouse and keyboard: ★★★☆☆ Tip: Ordinary keyboard, mouse, wireless gateway, printer, digital camera and MP4 power supply have little radiation, so you can use them safely. However, wireless keyboards and wireless mice radiate a lot. 3. Refrigeration and heating household appliances and electric blanket air conditioners have the longest use time and the largest power in the bedroom. Fortunately, their radiation is only 0. 1μT at the moment of switching on and off and during normal use, and the radiation value does not change much in various modes such as mute and sleep. In winter, some families like to use small electric heaters, heaters and other heating appliances, but the radiation is not small. Let's look at the infrared electric heater first. Test results of distance 1. 8μT means that the radiation above is 1.8 μ t, and the side is 5.4μT, so the radiation intensity is very high. We tested at a distance of 1mm, and the radiation decreased to 0.65438. The test result of heater close contact is 9. 3μT, that is, 0.34μT on the front and 0.25μT on the back at half a meter. However, the most reassuring thing is the Youting electric heater, which is 0.19 μ t in the center when it is used in high grade; The center of the side is 0. 18μT when it is near, and 0. 18μT when it is half a meter. When high-grade electric blanket is used, it is 0.7 1μT near the power supply, 1. 1.5μT at the left corner of the opposite side of the power supply, 0.7 1μT at the right corner of the opposite side of the power supply, and 0.55 μ t at the center of the electric blanket. At low gear, the left corner of the reverse side of the power supply is 0.70μT, and the right corner of the reverse side of the power supply is 0.49μT t. It seems that the radiation of the electric blanket is really not small. Another big radiation source in the bedroom is the electric fan, with low-grade wind of 2.6μT and high-grade wind of 0.9 μ t. However, when it exceeds 2m, the radiation decays to 0. 1 1 μ t, suggesting that the air conditioner has small radiation and can be used safely. However, infrared tube electric heaters, heaters and electric fans radiate a lot, so it is recommended to keep a distance of at least one meter when using them. Electric blankets also radiate a lot, so it is recommended to use them less. Humidifier, air purifier In the test, we found that this kind of fan humidifier has the largest radiation. The test result close to it is 49μT, the low-grade use is 15μT, and the high-grade use is 32μT, but when it exceeds 1m, it drops to 0.52 μ t. The test result of the ultrasonic spray humidifier is 9μT and 0.22μT outside 1 meter. The test result of the air purifier near it is 0.35μT, which drops to 0. 12μT within the range of 0.5m It is suggested that humidifiers and air purifiers should not be too close to human body. Humidifier radiation index: ★★★★★ Air purifier radiation index: ★★★★☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆97 It is suggested that the use time of induction cooker and electric hot pot should not be too long, and a certain distance should be kept when using. The microwave oven radiates the most when it is started. It is recommended not to get too close when cooking in the microwave oven. Radiation index: ★★★★★★★★★★ Refrigerator range hood ozone disinfection cabinet ozone machine electric cooker electric baking pan electric kettle juicer soya-bean milk machine refrigerator: 0. 13μT outside the door (open the door) 0. 16μT range hood: 0. 1 m front, 0.38μT front, 0. (0. 1 m) 0.30μT tip: refrigerators, ozone disinfection cabinet and rice cookers have little radiation, so they can be safely used; The radiation of electric baking pans and range hoods is slightly larger, which belongs to the early warning range. Be careful not to stick them too close when using. Ozone machine, soymilk machine and juicer all have relatively high radiation, so it is best not to let children use them. Vacuum cleaner, electric iron, hair dryer, power terminal board We have tested this big vacuum cleaner before, and the radiation under normal use is 15μT, but it is not small; This small hand-held vacuum cleaner is still very popular now. How much radiation does it have? We also did the test, and the distance from the handle was 0.03 m: 6.64 μ t; Left center: 4.22 μ t; But if you use it like this, its radiation will decay to a safe range, and the back is 0.2m: 0. 15μT t ... Radiation index of large vacuum cleaner: ★★★★★★ Radiation index of small vacuum cleaner: ★★★★☆ The radiation of electric iron is also quite large. We did another detailed test and found that the heating radiation of the electric iron would increase. In the heated state, at the handle, it is1.22μ t; However, under the condition of constant temperature, the radiation decays to 0. 12 μ t, so if ironing clothes, it is best to heat them once and then continue heating them later. Never iron clothes while heating. Radiation index of electric iron: ★★★☆ Hair dryer is also a major radiation source we found. In the previous test, the low match was 4.20μT and the high match was10.00μ t; After that, the different parts of the hair dryer were tested in detail under the condition of hot air, and the handle was 0.03 m,10.95 μ t; Air outlet, 7. 16μT, it seems that the hair dryer is really going to be used less. Radiation index of hair dryer: ★★★★★★★ ★ Another thing to remind everyone is that the power terminal board is only 0. 1 1μT if it is not connected with electrical equipment. However, when connecting high-power electrical equipment, when the distance is 0.03m, its radiation can be 1.25μT ... which will attract your attention. Radiation index of power terminal board (in use): ★★★☆ Text: The radiation of vacuum cleaner and hair dryer is large, and the radiation of electric iron is not small. Keep away from children when using, and the radiation of power terminal board should also attract your attention. Don't put it on the bedside. Electric footbath, treadmill, fat exercise machine This is a very popular electric footbath now. Let's see how much radiation it has. 0.03m away from the power line, 2.20μT t t. Radiation index of electric footbath: ★★★★☆☆☆ Some people like to exercise at home. How much radiation does this treadmill have? When the treadmill works, the panel is 0. 15μT, the front of the conveyor belt is 3.90μT, and the tail of the conveyor belt is 0. 1 1μ t ... The radiation index of the treadmill is ★☆☆☆☆☆☆☆☆☆☆☆☆☆973 Let's see how much radiation the fat exercise machine has. Fat body-building machine, side, high gear, 0.03 m, 5.48 μ t. Radiation index of fat body-building machine: ★★★★★★ ★ Note: the electric footbath and fat body-building machine have large radiation, and the front of the conveyor belt of the treadmill has large radiation. What kind of spectrograph is not too radioactive? In fact, as long as it is infrared, it is not within the scope of our test, and it is not electromagnetic radiation. So, you can use it with confidence. 4. Let's start with the desk lamp. This is the desk lamp in the master bedroom, and its radiation value is 0.17μ t. This is an energy-saving eye-protection desk lamp for children, and its radiation value is also 0.11μ t. The old desk lamp is used in the study, and its radiation value is 0.1μ t. The test result of fluorescent lamp is: master bedroom. It can be avoided without spending a penny. One of the most effective ways is to keep a distance, and it must be a safe distance of more than 3 meters. If you are at home, make reasonable arrangements, because experts suggest that it is best not to wear protective clothing. The human body itself is a big conductor, and wearing it can only introduce shielded radiation into the human body. Moreover, there is no clear material standard for protective clothing, and the price is uneven. Therefore, it is recommended that you do not trust the role of protective clothing. Maintain your health and edit this paragraph. 1. Face protection Although surfing the Internet is not an enemy, you still need to do full face work for severe electromagnetic radiation. Screen radiation produces static electricity, which is the easiest to absorb dust. Face to face for a long time is more likely to lead to spots and wrinkles. Therefore, before surfing the Internet, you may wish to apply skin care lotion and add a layer of calomel to slightly increase skin resistance. 2. Thoroughly clean the skin After surfing the Internet, the first task is to clean the skin, thoroughly clean the face with warm water and cleansing liquid, wash away all the electrostatically adsorbed dirt, and apply mild skin care products. Long-term use can reduce injuries, moisturize and beautify. This is really a little trick and a big role for women who surf the Internet. Keep your eyes open If you don't want to see people with red eyes, dark circles and gaunt faces the next day, don't fight continuously for a long time, especially don't stay up late surfing the Internet. Prepare a bottle of eye drops at ordinary times in case of emergency. It is also good to apply cucumber slices, potato chips or frozen milk and herbal tea after surfing the Internet. Its method: slice cucumber or potato, apply it on double eyelids, and close your eyes for a few minutes; Or use gauze to soak frozen milk herbal tea and apply it to eyes, which can relieve eye fatigue and nourish skin around eyes. Increasing nutrition is very important for people who often surf the Internet. Vitamin B group is very beneficial to mental workers. If you go to bed late, the quality of your sleep is not good. You should eat more animal livers and fresh fruits and vegetables, which are rich in vitamin B group. Meat, fish and dairy products increase memory; Chocolate, wheat doughnuts, seafood and dried fruits can enhance the coordination of the nervous system and are the best snacks when surfing the Internet. In addition, drinking Lycium barbarum juice and carrot juice from time to time also has obvious effects on eye protection and skin care. If you care about your appearance, quit those carbonated drinks and drink carrot juice or other fresh juice instead. Doing gymnastics regularly and surfing the Internet for a long time may make you feel dizzy, stiff fingers, backache, and even edema and varicose veins of lower limbs. Therefore, we should do gymnastics at ordinary times to maintain vigorous energy, such as lying flat on the bed before going to bed, relaxing the whole body, and putting our head back below the edge of the bed after use to alleviate the lack of blood supply and oxygen supply to the brain; Raise your feet and lie flat on the bed or sofa to reduce foot edema, help blood return and prevent varicose veins of lower limbs; Stretch from time to time during surfing the internet, stretch your muscles or lean on a chair, push your hands back, and stretch your tense and tired waist muscles; Shaking your fingers is the easiest way to completely relax your fingers. Remember, this kind of gymnastics does not exercise much, but it is far more effective than sleeping late. 2. Eye problems Long-term computer work not only makes my eyes sour, but sometimes makes my eyes blurred and I can't see clearly. This is caused by my excessive use of my eyes. The skin problems of my eyes are dark circles, increased fine lines and bags under the eyes. These questions are really a headache So how can we prevent and solve these problems in my eyes? Eye care, massage in the eye can improve blood circulation and help eliminate dark circles, but don't overdo it, otherwise it will make the eye muscles droop. Use eye gel containing chamomile, green tea and cucumber once a week. Bags under the eyes do harm the appearance, and once they are formed, they are difficult to eliminate. Long-term computer work will make eyes overtired, blood vessels dilate and eye muscles swell. At this time, you can close your eyes and apply a cotton pad to your eyes with frozen aloe juice, and lie still for a few minutes to improve the swelling. Don't ignore this edema phenomenon, which eventually accumulates into serious bags under the eyes, so we have to solve it surgically. Long-term use of eye fatigue, fine lines quickly climb to the eyes, you can tighten the water every day (eye-specific). Apply cotton to your eyes, or you can use eye mask. Sticking it once a day can quickly eliminate fine lines. If the fine lines become thick and deep wrinkles, it will be too difficult to maintain, so pay attention to the fine lines in the eyes and don't make them worse! You can install a screensaver, or put more cream on your computer! This can reduce radiation! If your monitor is relatively new, you should support a refresh rate of 85Hz, so that the displayed image will not flicker, shake or be unclear. This setting is usually enough. If the older one may only support 75Hz, it is also possible that the effect of 70Hz is slightly better than 75Hz, depending on the quality of your monitor. The resolution usually uses the recommended values of 1024*768 and 17 inch monitors. If you do word work and your eyesight is not very good, you can adjust it to 800 * 600; If you want to make a Cad drawing, you'd better use 1024*768 to set the taskbar to hide automatically. If you adjust the refresh frequency of the monitor to the above values respectively, you will see different display effects after careful observation, which may not be very different, which is related to your own eyes. Some people are sensitive to the flicker of light, while others feel nothing. In addition: 1. It is suggested to drink more green tea, which can reduce the radiation hazard of monitors. 2. Can you consider replacing CRT monitor with LCD to protect your eyes? Maybe you have no right? In view of the fact that the electromagnetic radiation generated by contact with electrical products in daily life may be harmful to health, the China Consumers Association issued a warning on August 6 that electromagnetic radiation must be prevented in life. Experts remind consumers: ● Don't concentrate household appliances too much or often use them together to avoid exposing yourself to the danger of excessive radiation. In particular, televisions, computers and refrigerators should not be concentrated in the bedroom. ● Various household appliances, office equipment, mobile phones, etc. Should be avoided for a long time. When electrical appliances, such as televisions and computers, need to be used for a long time, attention should be paid to leaving every hour, and the way of looking far away or closing your eyes should be adopted to reduce the fatigue of eyes and the influence of radiation. ● When the electrical appliance is suspended, it is best not to let it stand idly by, because it can generate weak electromagnetic field at this time and radiation accumulation for a long time. ● Keep a safe distance when using various electrical appliances. For example, the distance from the eyes to the TV screen is generally about 5 times the width of the screen; Leave one meter away after the microwave oven is turned on, and pregnant women and children should stay away from the microwave oven as far as possible; When using a mobile phone, the distance between the head and the antenna of the mobile phone should be as far as possible, and it is best to use a separate earphone and microphone to answer the phone. ● People living and working near high-voltage lines, radar stations, TV stations and electromagnetic wave transmission towers, patients wearing pacemakers and people living in modern electrical automation environment, especially pregnant women, children and the elderly with weak resistance, should be equipped with shielding protective clothing to block electromagnetic radiation if possible. ● TV, computer and other electrical equipment with display screen can be equipped with electromagnetic radiation protection screen, and users can also wear radiation protection glasses. The radiation generated by the display screen may cause dry skin, accelerate skin aging and even lead to skin cancer, so wash your face in time after use. ● The electromagnetic radiation released at the moment when the mobile phone is switched on is the largest. So it's best to ring the phone for a second or two or the phone rings twice before answering the phone. ● Eat foods rich in vitamins A, C and protein, such as carrots, tomatoes, kelp, lean meat, animal liver, etc., to strengthen the body's ability to resist electromagnetic radiation. How to solve computer skin? In the aspect of internal adjustment, try green tea and chrysanthemum tea, two weakly alkaline teas.
