Xiaobian decrypt household appliances radiation who is the largest

According to a report by Kyodo News Agency, Tokyo Electric Power Co., Ltd. announced on the 28th that the remote-controlled robot “Quince2” produced by Japan had detected strong radiation of 220 mS/h in the reactor building of Unit 2 of the Fukushima Daiichi Nuclear Power Station. The highest radiation value was Near the reactor containment cover on the 5th floor of the plant, the hourly value is 127-220 mSv. The humidity in the factory is also about 70%. Tepco stated: "It is difficult for humans to work in."

Radiation from nuclear power plants is terribly terrible. The radiation of household appliances cannot be ignored. In a family, the health of the family has always been our concern. In addition to televisions, refrigerators, washing machines, and microwave ovens, our home appliances include cell phones, telephones, and tablet computers. How much radiation do they have? Will it affect our physical health? The author will then discuss with you the issue of the radiation of household appliances. Interested friends may wish to find out.

What is the radiation intensity the human body can withstand?

Scientists currently believe that it is safe to have long-term exposure to electromagnetic radiation below 2 milligauss (approximately 20 μW/cm2). However, any form of artificial electromagnetic radiation has an effect on human cells. In order to prevent electromagnetic radiation pollution and protect public health, since the 1990s, the National Environmental Protection, Health, and other departments have successively formulated and issued seven regulations and national standards such as “Sanitary Standards for Environmental Electromagnetic Waves”, and stipulated grading standards for electromagnetic radiation:

A standard (safety standard, no effect on the human body) High-frequency radiation less than 10 μW/cm2

Low-frequency radiation less than 10 V/m

Secondary standard (middle zone, which has a detrimental effect on the human body) High-frequency radiation less than 40 μW/cm2

Low frequency radiation less than 25 V/m

In understanding the above radiation values, let us first understand the conversion of the radiation value, 100μw/cm2 = 10 milligaussian = 1μt, this time we measured the value of the radiometer is "μT" as a unit, so less than 0.1 μT is an absolute safety range, and 0.1μT-0.4μT is in the secondary standard range, but it can have harmful effects on the human body.

The household appliances in our home are mainly magnetic radiation, and the frequency bands are divided into industrial and radio frequency bands. The work frequency bands mainly include televisions, computers, hair dryers, refrigerators, etc., and the unit is μT. The radio frequency bands mainly include mobile phones, microwave ovens, and the like, and the unit is μW/cm2. In the next evaluation, we will perform tests and numerical conversions based on the corresponding frequency bands. The following are the radiation star types of various types of home appliances and electronic equipment: (five stars, is a serious violation, to pay attention; Samsung above, is beyond the scope, but also to attract attention; a star, safe, can be used with confidence), hoping to cause people Attention.

Five-star home appliance radiation: ★★★★★

1. Microwave oven: The radiation at the door seam is the largest, the radiation at the start is the maximum, and the cooking should not be too close. The radiation range can reach 7 meters.

2. Electric blanket: After the electric blanket is energized, it will produce an electromagnetic field and produce electromagnetic radiation. If pregnant mommy uses electric blankets for a long period of time, these electromagnetic radiations will most likely affect the fetus's brain, nerves, bones, and heart and other vital organs and tissues.

3. Humidifier: The radiation of the humidifier, which is particularly favored by women, is so large that it should never be placed too close to the body. It is close to 100 milligauss and drops to 1 milligauss after leaving 1m.

4. Vacuum cleaner: 50 milligauss at 30cm, 70cm can be reduced to 2 milligauss. Stay away from being better.

5, fat exercise machine: the front of the conveyor belt radiation is large, exercise time should not be too long, to minimize radiation.

Four-star home appliance radiation: ★★★★☆

1, high-power equipment: the moment of radiation when connected, do not put on the bed.

2, hair dryer: Although small, but the radiation is great, use should be away from children. When opening and closing the hair dryer, try to stay away from the head. When using it, it is best to keep the hair dryer perpendicular to the head. Do not use it for a long period of time.

3, CRT TV: that is, ordinary television, behind the radiation is greater, need to maintain a certain distance when viewing, especially children. It is best to maintain a distance of 2 meters when watching TV. There is proper lighting in the room. Do not watch TV for more than two hours continuously. After watching the TV wash your face, clean up the radiation absorbed by the facial skin.

4, home theater: usually refers to the video player plus audio system, as little as possible, if you want to sing best go to KTV.

5, subwoofer speakers: Most computer speakers are very close to the computer, experts recommend using at least half a meter away from the body to keep at least half a meter distance, especially connected to the computer's subwoofer speakers, should not be placed near The position of the human brain.

6, infrared tube heater 7, fan: use time not too long, and maintain a certain distance.

8, Induction Cooker: Now more and more families like to cook with electromagnetic oven, but pay attention to the use of time not too long.

9, the iron: the temperature once heated in place, use a while to continue heating, do not heat while ironing clothes. Keep away from children when using.

Three-star home appliance radiation: ★★★☆☆

1. Plasma TV: For traditional CRTs, the radiation of LCD TVs and plasma TVs is much smaller. However, there are still some adverse effects. It is recommended that the use time should not be too long.

2, desktop computer host: the host's rear, side radiation is large, it is recommended not to facilitate the heat dissipation, open the use of the chassis, reduce radiation damage to the human body.

3, wireless mouse and keyboard: Because it is a wireless mouse and keyboard, it will generate radiation when transmitting and receiving operating signals.

4, electric foot basin 5, air purifiers weaker electrical intensity is what?

Two-star home appliance radiation: ★★☆☆☆

1, range hood: Note that when using not too close.

2, electric baking pan 3, treadmill star radiation: ★ ☆ ☆ ☆ ☆

1, LCD TVs, monitors: LCD products selling point is less radiation, consumers can rest assured that use.

2. Laptops: The radiation is concentrated on the top of the keyboard and should be kept at a distance from the power adapter when used.

3, air conditioning: Although classified as low-emission electrical appliances, but according to the test will increase the radiation, while taking into account the impact of the next door and downstairs air-conditioning machinery, try to leave the bed. It also has low electromagnetic waves when not in use.

4, refrigerator 5, ozone disinfection cabinet 6, rice cookers: Although radiation is small, but as far as possible away from children.
