Radiation can be said to be everywhere. In daily life, our commonly used electrical appliances generate radiation when they are working. How to deal with these radiations in daily life? Xiaobian today takes everyone to see how experts teach us to resist radiation.
Refrigerator: Don't worry about radiation
The kitchen area is small, and many family refrigerators can only be placed in the living room. The big man's "cold" guy, the booming sound when he starts, makes people worry that his radiation will not hurt his family?
The radiation of the refrigerator is mainly electromagnetic radiation. "The back of the refrigerator is hot, but its electromagnetic radiation is not high, the electric field strength is only 5 volts / meter, even lower than the front door handle." Experts said. The electric field strength of the door handle of the refrigerator reaches 10 volts/meter because of the liquid crystal display at the handle. Experts pointed out that there is a circuit board behind the LCD screen, so the radiation is large.
However, you don't have to worry about the radiation of the handle, because whether it is 5 volts or 10 volts, it is a national standard far below the electric field strength of 4000 volts/meter, so the amount of radiation is negligible. The magnetic field strength of the refrigerator is not large. The telecom engineer and the volunteer of the Darwin Natural Knowledge Society, Cheng Jing, have detected the electromagnetic radiation of the refrigerator. Close to the compressor, the magnetic field strength is up to 0.5 micro volts, and the national standard is 100 micro volts.
How to deal with it: Don't worry about it overall, but if you are still not sure, don't buy a refrigerator with a LCD screen, or when you switch the refrigerator door, the body is half a meter away from the refrigerator.
Microwave oven: maximum doorway radiation
The radiation of microwave ovens has been known to everyone. How can we prevent it?
The experimental test data is that the electromagnetic radiation of the door joint is the highest when the microwave oven is working, which is 5-10 microwatts/cm 2 , but lower than the national standard of 40 microwatts/cm 2 . Experts have found that the strongest part of the radiation is the control panel, which is nearly 20 volts/meter, while the microwave cavity, including the door joints, is less radiated, less than 10 volts/meter.
How to deal with it: Experts say that the microwave oven will only leak through the door when it is working. So, when you press the switch, hurry and leave, wait until it finishes running to pick up the food. Also consider buying a radiation protection apron.
Computer: Radiation is exaggerated
Many people worry that computer host radiation is harmful to human health, especially for expectant mothers. The first thing that is warned by others is "use less computers."
In fact, research shows that the radiation of the computer is exaggerated. When the detection is close to the chassis, the magnetic field strength is only 1 to 2 micro-spec. The magnetic field strength of liquid crystal displays is between 0.1 and 0.2 microwatts. People are worried that their radiation is mainly due to psychological fear. In addition, some merchants exaggerate the damage of the computer's electromagnetic field to the human body in order to promote their products.
Coping method: Although the radiation is small, but it can not be used for a long time, so it is recommended that the computer family eat more carrots, cabbage, bean sprouts, tofu, red dates, oranges and milk, eggs, animal liver, lean meat and other foods. You can also drink more tea, and the active substances such as tea polyphenols in tea are good for absorbing and resisting radioactive substances.
Hair dryer: 5 cm is safe
Although the hair dryer is small, the instantaneous high temperature and wind speed make many people worry about the "magic power" of the motor inside it.
Yes, the radiation from the hair dryer is indeed quite high. Research shows that the motor is close to the power of 800 watts and the data is 20 micro tex.
Fireproof cables, the widely used fireproof cables at present, mainly include UL series flame retardant cables and flame retardant low smoke zero halogen cables. In the imported products mainly from the Americas and Europe, because the fireproof cable standards in the Americas and Europe are incompatible with each other, the fire prevention ideas are very different. Therefore, Party A and the design institute are in a passive state when selecting products, each with its own In the end, it is often chosen according to the actual situation of the funds.
