People who work, study and live in an environment where radiation sources are concentrated are prone to insomnia, memory loss, weakness, low immunity, etc., and their cancer cells grow twenty-four times faster than normal.
How far is radiation from us In our living environment, radiation is everywhere!
Household appliances: television, refrigerator, air conditioning, microwave ovens, vacuum cleaners, etc.
Office equipment: cell phones, computers, photocopiers, electronic instruments, medical equipment, etc.
Home decoration: marble, laminate flooring, wallpaper, paints, etc.
Surrounding environment: high-voltage power lines, power substations, television (radio) signal transmission towers, etc.
Natural environment: sunspots, etc.
A healthy person can withstand a brief load of 5000R, but only 700R dose are enough to make a healthy person fatal threat, but each person's body resistance is different, and each person will have different degrees of symptoms. Generally exposure to electromagnetic radiation pollution can cause headaches, insomnia, heart rate irregularities and other central nervous system problems. At the same time, for some people's eyes may have an impact, vision loss, skin diseases and other phenomena, heavy and may cause cancer. For pregnant women, it may lead to miscarriage, and elderly people with cardiac pacemakers should be especially careful. At the same time, different people or the same person at different ages on the tolerance of electromagnetic radiation is not the same, even in the excessive environment, does not mean that all people will get sick, so there is no need to electromagnetic radiation "grass". However, the elderly, children, pregnant women or patients with pacemakers, sensitive to electromagnetic radiation and long-term work in the environment of excessive doses of electromagnetic radiation should take precautionary measures.
Protection of specific electrical equipment in the home points
Electrical radiation index
Electrical radiation index of the implementation of the five-point system, where it is rated five points, are serious exceeded the standard, can be caused by you to pay attention to; more than three stars also belongs to the scope of the exceeding standard, but also to cause you attention; a star, is safe, you can rest assured that the use of.
Electromagnetic radiation is divided into two levels, including the frequency band of the unit is μT, if the radiation in the 0.4 μT or more belongs to the stronger radiation, the human body has a certain degree of harm, long-term exposure to susceptible to leukemia. If the radiation is below 0.4μT, it is relatively safe. The unit of RF electromagnetic wave is μW/㎝2.
1.TV
Traditional CRT TV is the first one to be tested. We first tested it in close proximity. Within half a meter from the front, the radiation value it produced was 0.12μT at the moment of normal power-on, 0.30μT during normal viewing, 0.27μT when changing channels, and 0.11μT in standby mode, while the radiation value on the side during normal viewing was 0.28μT, which seemed close to the warning value in general.
Because most people watch TV at a distance of about 3 meters, we also did a test at 3 meters on the front side, and found that there is a great degree of attenuation of radiation: switching on and off, normal viewing, changing channels, and standby status are all 0.12μT, the test results show that the traditional tube TV will not be harmful to normal viewing. But to our surprise, it is in the back of the greater intensity of radiation, power on within half a meter of the radiation value of 4.8 μT, and across the glass, wood, radiation has not been reduced, and even across the 10-centimeter-thick wall radiation value of 0.9 μT. If your TV behind the head of the bedroom bed can be careful. But people usually rest and watch TV at different times, so it's not a big problem.
Then look at the plasma TV, front half a meter, power on, watch, change the channel are 0.11μT, standby 0.12μT, side 0.11μT; in the front of the 3 meters, power on 0.12μT, normal viewing is 0.14μT, change the channel, standby 0.11μT, from the results of the test compared to the traditional TV, the intensity of radiation of the plasma to be a little smaller.
And rear-projection TV, normal viewing, close to the front of the body 0.12μT, side 0.19μT, behind 0.14μT; front half a meter at 0.11μT; front 3 meters at 0.1μT.
In the TV series is the most reassuring is the LCD TV, whether it is the front of the front half a meter or the front of the 3-meter range, the moment of the power on, normal viewing, change the station, The test results for the standby state were all 0.1μT, while the side was only 0.11μT, essentially no change in radiation intensity.
Test results: after the comparison of three kinds of TVs, it is easy to find that LCD TVs, rear projection TVs radiation is the smallest, plasma TVs radiation is slightly stronger, CRT TVs are larger, but mainly in the back of the TV, suggesting that it is best to maintain a certain distance when you watch, especially children.
2. DVD player and home theater
These years the popular home theater, that is, the DVD player plus sound system, close to the results of the test, the DVD 1.2μT, OK machine 1.2μT, amplifier 1.24μT, 1.5μT small speakers, large speakers 0.49μT, if the same time to turn on the radiation can be not small.
Tips: We recommend that you use the home theater as little as possible, if you want to sing the best or go to the KTV.
CRT monitors, LCD monitors, desktop computers, small speakers, laptops
People have always thought that CRT monitors are more radioactive, in the end, it is not what we think it is? We first tested it, the front of the display is close to 1.00μT, the side of the display is close to 0.55μT, which is not small ah! In the look at the center of the display, the distance of 0.03 meters, the radiation is still 0.55μT, is this CRT display is really as big as we think the radiation? In order to further confirm, we began to look for its safe distance, the results found that the distance of 0.2 meters, in front of the display of radiation attenuation to 0.18μT, it seems that CRT monitors as long as to maintain a distance of 0.2 meters can be used without fear. Some viewers asked if it is the same as CRT TV behind the larger radiation, the test found that it is not large. Some people like to use anti-radiation screen saver, does it work? We also made a special test of it, plus the screen protector radiation only 10% reduction, it seems that the role of the screen protector is not big.
CRT monitor radiation index: ★★★★★☆☆
Today's LCD monitors are replacing traditional monitors, and we also tested it. 0.11μT at 0.5 meters in front of the display, 0.12μT at the moment of power-on, 0.11μT at power-off, 0.12μT at 0.5 meters to the side of the display, it seems that LCD monitors are really quite reassuring.
LCD radiation index: ★ ☆☆☆☆
Let's take another look at the host of the desktop computer, the front 0.17μT, but the host of the central operating panel radiation is slightly stronger, the distance of 0.03 meters, 0.26μT; the host side of the 0.29μT, the left side of the chassis face the center of the distance of 0.03 meters, 0.23μT. 0.46μT behind, but we generally There is a certain distance from the back of the mainframe, so the impact is not significant. There is a moment of power on, standby state are 0.17μT. Another thing to say is that the desktop computer power wiring if then connected to the state of radiation is 0.47μT, so then use desktop computers should also keep the distance.
Desktop computer host radiation index: ★★★★☆☆
But the next test is not very optimistic, subwoofer speakers, the center of the operating panel, distance 0.03 meters, 0.63μT; speakers right side of the face of the center, the distance of 0.03 meters, 5.68μT; radiation but is not small, it's a safe distance is how much? After careful testing found that when the distance of 0.4 meters, its radiation is reduced to 0.17μT. So the subwoofer speaker radiation is serious, use at least half a meter distance.
Radiation index of the subwoofer speakers: ★★★★☆
The last thing to say is that the laptop, 0.1 meters in front of the display 0.13 μT, 0.3 meters in front of the display 0.10 μT, the display side of 0.3 meters 0.13 μT, 0.19 μT above the keyboard, the power adapter 0.22 μT. The test results show that the laptop keyboard radiation is slightly stronger, the power adapter is the largest. The power adapter is the largest.
Notebook radiation index: ★ ☆☆☆☆
Tips: LCD radiation is very small, CRT monitors slightly larger, but are in the safe range; host behind, side radiation is larger, we strongly recommend that you do not in order to dissipate heat for convenience, open the chassis to use; the subwoofer speaker radiation is serious, use at least keep half a meter away; laptop radiation is concentrated in the upper part of the keyboard, the use of the power adapter should be with the power adapter. When using a laptop, you should keep a distance from the power adapter.
Hey, by the way, the light said that this computer and laptop radiation is not big, but that photoelectric mouse a moment of red a moment of blue is quite scary, there is radiation? That wireless mouse, wireless keyboard is not radiation is smaller than ordinary? There are also wireless LAN transmitters!
This is the first time I've ever seen a digital camera with a battery, and I've never seen a digital camera with a battery, so I'm not sure if it's a good idea to use a battery, but it's a good idea to use a battery.
Ordinary mouse: 0.1μT
Ordinary keyboard: 0.11μT
Wireless mouse: 0.53μT (above the mouse)

Tip: Ordinary keyboards, mice, and wireless gateways, printers, digital cameras and MP4 power radiation is not large, can be used without fear. But the wireless keyboard, wireless mouse radiation.
3. Cooling and heating appliances, electric blankets
Air conditioning is the longest used in the bedroom, the largest power, it is gratifying to switch on and off instantly, normal use of its radiation is only 0.1μT, in the mute, sleep, and other various modes of radiation value changes are also small.
In winter, some families like to use small electric heaters, heaters and other heating appliances, but their radiation is not small, first look at the infrared heater, the results of the test at a distance of 1mm: above the radiation is 1.8μT, side 5.4μT, radiation intensity is very large, we did another 1m away from the test, the radiation was cut to 0.14μT. heater close to the test results are 9.3μT, the radiation value in various modes, including silent, sleep, etc. also changes little.
When the electric blanket is used in high grade, it is 0.71μT near the power supply, 1.15μT in the left corner of the power supply side, 0.71μT in the right corner of the power supply side, and 0.55μT in the center part of the blanket; when it is used in low grade, it is 0.70μT in the left corner of the power supply side, and 0.49μT in the right corner of the power supply side, and it seems to be quite a lot of radiation from the blanket.
The other big source of radiation in the bedroom is the electric fan, 2.6μT in low wind, 0.9μT in high wind; however, 2m away, the radiation is attenuated to 0.11μT.
Tips: air-conditioning radiation is relatively small, you can rest assured that you can use it, but infrared tube heater, heater, fan radiation is greater, it is recommended that you use at least keep a meter away from the use of electric blankets. Electric blanket radiation is also larger, it is recommended to use less.
Humidifiers, air purifiers
We found that this fan humidifier has the highest level of radiation in our tests, with a result of 49 μT when tested close to it, 15 μT when used in a low gear, and 32 μT when used in a high gear, though it was cut to 0.52 μT when used at a distance of 1m. The ultrasonic spray humidifier tested close to it was 9μT, and 1m away was 0.22μT. The air purifier tested close to it was 0.35μT, and 0.5m away was cut to 0.12μT.
Tip: Humidifiers and air purifiers should not be placed too close to the human body.
Humidifier radiation index: ★★★★★
Air purifier radiation index: ★★★★☆☆
Induction cooker electric hot pot microwave
Like to use induction cooker hot pot people can pay attention to it, it's radiation is not small, look at the results of the test, induction cooker above the 0.1m 2.80μT, induction cooker above the 0.3m 1.40μT
The test results show that the induction stove is more radioactive, and the electric cooker is better compared to the induction stove.
After that, we first tested the microwave oven which we are most concerned about and found that the radiation is the biggest in the doorway of microwave oven, so we did a detailed test:
Medium-range fire: 0.03 meters in front of the doorway 17.32μW/㎝2,
0.3 meters in front of the doorway 2.01μW/㎝2
1 meter in front of the doorway 0.41μW/㎝2
The radiation is the biggest in the doorway. p>
Center of microwave oven door: 1m from the door: 150.7μW/㎝2
The test result shows that the radiation is the highest when the microwave oven is activated (the value (0.05m from the door) is around 18 to 22μW/㎝2,).
Tips: Induction cooker radiation is large, electric hot pot is relatively small, it is recommended to use the induction cooker, electric hot pot time is not too long, use should also maintain a certain distance. Microwave ovens start when the radiation is the largest, it is recommended that you do not get too close when cooking with a microwave oven.

Vacuum cleaners, irons, hair dryers, power terminals
We tested this large vacuum cleaner before, the radiation under normal use is 15μT, but it is not small ah; now also popular with this small handheld vacuum cleaner, how much radiation is it? We also did a test, the handle at a distance of 0.03 meters: 6.64 μT; the left side of the face of the center: 4.22 μT; however, if you use this, its radiation can be attenuated to a safe range, the back of the 0.2 meters: 0.15 μT.
Large vacuum cleaner radiation index: ★★★★★
Smaller vacuum cleaner radiation index: ★★★★☆
Iron is also quite a bit of radiation, but it's not a big deal.
The radiation of the iron is also quite large, we did a detailed test, and found that the radiation will increase when the iron is heated, in the heating state, the handle, 1.22μT; however, it is in the constant temperature state, the radiation is attenuated to 0.12μT. Therefore, if you are ironing clothes, it is best to heat the temperature in place at one time, and then continue to heat for a while, do not heat the ironing while you heat it up.
Iron radiation index: ★★★★☆
Hairdryer is also a big source of radiation we found, before the test, low-grade 4.20 μT, high-grade 10.00 μT; and after the hot air gear, the hair dryer in different parts of the detailed test, the handle at 0.03 meters, 10.95 μT; outlet, 7.16 μT, it seems that the hair dryer also really It seems that the hair dryer really should be used less.
The radiation index of the hair dryer: ★★★★★
There is another point to remind you is that the power terminal board, if there is no electrical equipment connected to the distance of 0.03 meters, its radiation is only 0.11 μT, it is not big; but in the high-power electrical equipment connected to the distance of 0.03 meters, its radiation can be 1.25 μT. This can be cause for you to pay attention to.
The radiation index of the power terminal board (in use): ★★★★☆
Text: The radiation of vacuum cleaner and hairdryer is large, and the radiation of iron is not small, so it should be far away from the children, and the radiation of the power terminal board should be paid attention to, and it should not be put at the head of the bed.

Tips: Electric Footbath Radiation, Fat Exercise Machine Radiation are all larger, and the front of the treadmill conveyor belt is more radioactive.
What spectrum meter and so on is not radiation is not small ah?
In fact, as long as the infrared are not in the scope of our test, and it produces is not electromagnetic radiation. So you can rest assured that you don't have to worry.
4. Lamps
First from the lamp, this is the master bedroom lamp, its radiation value is 0.17μT, this is the children's use of energy-saving eye lamps, its radiation value is also 0.11μT, the study is the use of old-fashioned lamps, its radiation is 0.1μT.
The fluorescent lamps are tested: the master bedroom 0.12μT, the living room 0.18μT, the study 0.18μT, the lamp is 0.12μT, the lamp is 0.12μT, the lamp is 0.12μT, the lamp is 0.18μT, the lamp is 0.12μT, the lamp is 0.18μT, the lamp is 0.18μT.
The test results for fluorescent lamps were: master bedroom 0.12μT, living room 0.18μT, study 0.11μT, and children's favorite cartoon wall lamps, which radiated 0.11μT.
Hint: The radiation of all kinds of lamps and lanterns passed the test, so you can use them without worrying about the radiation.
No need to spend any money to avoid it. One of the most effective ways is to keep a distance, and it must be a safe distance of more than 3 meters.
That if the home should be rationalized, because experts recommend that it is best not to wear protective clothing, the human body itself is a large conductor, wearing it can only be shielded radiation into the human body, and now there is no clear standard for the material of the protective clothing, the price is also uneven, so it is recommended that you do not gullibly protect the role of clothing.
