The most authoritative radiation evaluation report

The implementation of the five-pronged approach, all rated as five points, are seriously exceeding the standard, you need to pay attention to it; Samsung and above are also

Beyond the standard range, you should also pay attention to; one star, is safe, you can rest assured to use.
Electromagnetic radiation is divided into two levels, in which the Unit of the working frequency is μT. If the radiation is more than 0.4 μT, it is a strong radiation, which is harmful to the human body and is susceptible to leukemia for a long time. It is relatively safe if the radiation is below 0.4 μT. RF electromagnetic

The unit of the wave is μW/㎝ 2.
Traditional TV CRT is the first to be tested. We first conduct a close-range test on it. In the range of half meters on the front, the radiation produced by the normal start is 0.12 μT, when normal viewing is performed, the radiation value is 0.30 μT, the time for switching is 0.27 μT, and the standby status is 0.11 μT. When the side is normal, the radiation value is 0.28 μT, which is close to the warning value in general. Because most people watch TV at a distance of about 3 meters, we also tested the front 3 meters and found that the radiation has a great degree of attenuation: the switch-on, normal watching, switching, and standby status are all 0.12 μT. The test results show that normal watching of the traditional video tube TV will not cause harm. However, what surprised us was that the radiation intensity behind it was large. After the boot, the radiation value within half a meter could reach 4.8 μT, and the radiation was not reduced across glass and wooden boards, even a wall of 10 cm thick has a radiation value of 0.9 μT. Be careful if your TV is right behind your bed in the bedroom. However, people usually have different time to rest and watch TV, so the problem is not big.
Then watch the plasma TV. The front side is half a meter, and the power starting, watching, and changing is 0.11 μT. The standby side is 0.12 μT, and the side is 0.11 μT. The front side is 3 meters, the radiation intensity of plasma is smaller than that of traditional TVs, including 0.12 μT at startup, 0.14 μT at normal viewing and 0.11 μT at standby.
While the back-cast TV, normally watching, close to the front of the fuselage 0.12 TB, side 0.19 TB, behind 0.14 μT; front half 0.11 μT; 3 M on the front side, 0.1 μT.
LCD TVs are the most reassuring in the TV series, regardless of the front half meter or the front three meters, the testing results of the instant boot, normal viewing, change, and standby status are both 0.1 μT, and the side is only 0.11 μT. Basically, the radiation intensity remains unchanged.
Test Results: After comparison of the three TVs, it is not difficult to find that LCD TVs and backend TVs have the least radiation, while plasma TVs have a little stronger radiation, while CRT TVs are large, but they are mainly behind TVs, it is recommended that you maintain a certain distance during watching, especially for children.
DVD players and home cinemas have been popular in the past few years, that is, the audio system of the DVD player is closely followed by the test results. dvd1.2 μT, okserver 1.2 μT, power amplifier 1.24 μT, small speaker 1.5 μT, large speaker 0.49 μT, if you open at the same time, the radiation is not small.
Tip: We recommend that you try to use less cinemas. If you want to sing, you 'd better go to KTV.

CRT display LCD desktop computer host small speaker laptop
People always think that the CRT display has a large amount of radiation. Do you think that is the case? We first tested it. The display screen was placed closely at 1.00 μT and the display side was closely at 0.55 μT, which was not small! Looking at the center of the display screen, the distance is 0.03 meters, and the radiation is still 0.55 μT. Is this CRT display as big as we think? In order to further confirm, we began to look for its safe distance and found that when the distance was 0.2 meters, the radiation in front of the display reduced to 0.18 μT, it seems that the CRT display can be used at a distance of 0.2 meters. A friend of the audience asked if it was the same as a crt TV with a large background radiation. After the test, it was found that it was not large. Some people like to use anti-spoke ##### Screen Saver. Does it work? We also specifically tested it. In addition, the screen saver radiation only reduced by 10%, it seems that the Screen Saver is not very effective.
Radiation index of CRT display:★★★☆☆
Now LCD is replacing traditional display, and we have tested it. The front of the display screen is 0.5 Mu t, the boot instantly is 0.11 Mu t, the shutdown is 0.12 Mu t, and the display side is 0.11 Mu T. It seems that the LCD display is quite reassuring.
LCD radiation index:★☆☆☆☆
Let's take a look at the desktop computer host, with a front of 0.17 μT, but the central radiation of the host operation panel is slightly strong, with a distance of 0.03 meters and 0.26 μT; The host side is 0.29 μT, the center of the left side of the chassis, Which is 0.03 m away and 0.23 μm. The back end is 0.46 μT, But we generally have a certain distance from the back of the host, so the impact is not big. In addition, the instant boot and standby status are both 0.17 μT. In addition, we also need to talk about the desktop computer power wiring. If the radiation in the connected state is 0.47 μT, we need to keep the distance when using the desktop computer.
Desktop Computer Host radiation index:★★★☆☆
However, the next test is not very optimistic. The center of the speaker, the operating panel, and the distance is 0.03 meters and 0.63 μT. The center of the right side of the speaker is 0.03 meters and 5.68 μT; the radiation is not small, so what is the security distance? After careful tests, it is found that when the distance is 0.4 meters, its radiation is reduced to 0.17 μT. Therefore, the speaker of the subwoofer has severe radiation, and the distance between half a meter is needed.
The radiation index of the subwoofer speaker:★★★★☆
The last thing we need to talk about is the laptop. The front of the screen is 0.1 m 0.13 μT, the front is 0.3 m 0.10 μT, the side is 0.3 m 0.13 μT, and the top of the keyboard is 0.19 μT, power adapter 0.22 μT. The test results show that the notebook keyboard has a little stronger radiation and the maximum power adapter.
Laptop radiation index:★☆☆☆☆
Tip: the LCD screen has little radiation, while the CRT display is slightly larger, but all are in a safe range. The background and side of the host have a large radiation. We strongly recommend that you do not open the chassis for ease of heat dissipation; the Speaker of the subwoofer is subject to severe radiation and must be at least half a meters away during use. the notebook is concentrated on the top of the keyboard and should be farther away from the power adapter when using the notebook.
Ah, by the way, it is said that the computer and notebook have little radiation, but the photoelectric mouse is red and blue for a while. Is there radiation? Is the wireless mouse and keyboard less radiant than normal? And the wireless LAN transmitter! There are also digital equipment, what digital cameras, MP3 and MP4.
Tell you, this battery DC is the safest.

Refrigeration and heating appliances, electric blankets
The air conditioner has the longest use time and the largest power in the bedroom. It is gratifying that the radiation of the air conditioner is only 0.1 μT during instant and normal use on/off, in various modes such as mute and sleep, the radiation value does not change much.
Some families like to use small electric heating, heating fans and other heating appliances in winter, but their radiation is not small, first look at the infrared electric heating, the test result of 1mm distance is: The above radiation is 1. 8 μT, side 5.4 μT, the radiation intensity is very large, we did a test outside 1 m, the radiation is reduced to 0.14 μT. The test result of the heater is 0.34 μT, 0.25 μT on the front and μT on the back. However, the most reassuring thing is the oil ting electric heating, high-grade use, the center of the top 0.19 t; the center of the side, close to 0.18 T, half meter 0.18 T.
Electric blanket, in high-grade use, close to the power supply is 0.71 μT, power supply side of the left corner of 1.15 μT, power supply side of the right corner of 0.71 μT, electric blanket central part of 0.55 μT; when the power supply is low, the left corner of the power supply side is 0.70 μT, And the right corner of the power supply side is 0.49 μT. It seems that the radiation of the electric blanket is not small.
Another major radiation source in the bedroom is an electrical fan, with a low-end wind power of 2.6 μT and a high-end wind power of 0.9 μT. However, outside of 2 m, the radiation degrades to 0.11 μT.
Tip: the air conditioner has little radiation and can be safely used. However, the radiation of the infrared tube heating, heater and fan is large. We recommend that you keep the distance of at least one meter during use. Electric Blanket radiation is also large, it is recommended to use less.

Humidifier, Air Purifier
In the test, we found that the fan humidifier has the largest radiation, and the test result is 49 μT, 15 μT for low-end use, and 32 μT for high-end use, however, it is reduced to 0.52 μT in 1 m. The result of the test is 9 μT, and 0.22 μT outside 1 meter. The test result of the air purifier is 0.35 μT, which is reduced to 0.12 μT in the range of MB.
Tip: the humidifier and air purifier should not be too close to the human body.

Induction Cooker electric hot pot Microwave Oven
People who like to eat hot pot with an Induction Cooker should pay attention to it. Its radiation is not small. Let's take a look at the test results. The top of the Induction Cooker is 0.1 m 2.80 μT, and the top of the Induction Cooker is 0.3 m 1.40 μT, the front of the Induction Cooker is closely connected to 8.70 μm, and the front of the Induction Cooker is 0.3 μm and 1.00 μm. Let's take a look at the electric hot pot test. The high-end power-on is 0.53 μT, and the power-off is 0.13 μT.
The test results show that the Electromagnetic oven has a large radiation, and the electric hot pot is better than the Induction Cooker.
Then we first tested the microwave oven that everyone was most concerned about, and found that the microwave oven had the largest radiation at the door joint, so we did a detailed test:
Mid-range firepower: 0.03 m 17.32 μW/㎝ 2 before door seams,
0.3 m 2.01 μW/12002 before door Seams
1 m 0.41 μW/12002 before door Seams
Microwave Oven door center: 0.05 m from door 30.14 μW/1272
The test results show that the maximum radiation is reached when the microwave oven is started (the value ranges from 18 to 22 μW/㎝ 2 ,).
Tip: The Induction Cooker has a large radiation intensity and a relatively small electric hot pot. It is recommended that the time of the Induction Cooker and electric hot pot be kept at a certain distance during use. The microwave oven has the largest radiation when it starts. We recommend that you do not approach it too closely when cooking in a microwave oven.

The electric iron has a very large radiation. We did a detailed test and found that the radiation will increase when the electric iron is heated. In the heating status, the handle is at 1.22 μT; however, at a constant temperature, the radiation degrades to 0.12 μT. So if you iron the clothes, it is best to heat the temperature once in place, and then continue heating later, Do not heat while iron the clothes.
Electric Iron radiation index:★★★★☆
Hair dryers are also a large radiation source we found. In the previous tests, we tested low-end 4.20 μT and high-end 10.00 μT. Later, we tested different parts of the hair dryers in detail during hot air files, the handle is 0.03 meters and 10.95 μT; the air outlet is 7.16 μT. It seems that the hair dryer really needs to be used less.
Radiation index of hair dryer:★★★★★
Another thing to remind everyone is that if the power supply board is connected to useless electrical equipment at a distance of 0.03 meters, its radiation is only 0.11 μT, which is not large; but when connected to high-power electrical equipment, at a distance of 0.03 meters, its radiation may be 1.25 μT. This will attract your attention.
Radiation index of the Power wiring board (in use:★★★★☆
Tip: the radiation of the vacuum and hair dryers is large, and the radiation of the electric iron is not small. It should be farther away from the children when using it, and the radiation of the Power wiring board should also attract your attention. Do not put it on the bed.

What kind of analyzer does it mean a lot of radiation?
In fact, as long as it is infrared, we do not test the range, and it does not produce electromagnetic radiation. So you can rest assured that you do not have to worry about it.
Lamps
Starting from the lamp, This is the lamp in the master bedroom. Its radiation value is 0.17 μT. This is an energy-saving eye-protection lamp for children. Its radiation value is also 0.11 μT, the study uses an old-fashioned desk lamp with a radiation of 0.1 μT.
The test result of the fluorescent lamp is as follows: the master bedroom is 0.12 μT, the living room is 0.18 μT, and the study is 0.11 μT. There is also a cartoon wall lamp that children like. Its radiation value is 0.11 μT.
Tip: the radiation of various lamps is acceptable and can be safely used.
You can avoid it without spending any money. One of the most effective ways is to keep the distance, and the safe distance must be more than 3 meters.
If it is necessary to make reasonable arrangements at home, because experts suggest that you do not wear protective clothing. The human body itself is a large conductor, which can only import the shielded radiation into the body, and there is no clear material standard for protective clothing, and the price is also uneven, so we recommend that you do not trust the role of protective clothing
