Bed is probably to be considered the measurement of electromagnetic fields in the home of the main event. If you sleep in a place with a high magnetic field for a long time, you can imagine how big the effect is. It is also known that the so-called "bedside stereo" should not be placed at the head of the bed. In principle, any electrical appliances should be kept away from your bed. Travelers always complain about poor sleep quality, in fact, is likely to be placed near the hotel bed heater, fan, air freshener, air conditioning and other electrical appliances, to know that a small electric heater can be as high as the magnetic field of more than 200mG.
Microwave oven only plugged in unused radiation
With other appliances is different, microwave oven even if only plugged in the electricity did not use it, some models of the front keypad magnetic field can still be as high as 30 ~ 60mG, the use of the magnetic field of more than 200mG. In addition, studies have shown that the leakage of microwave damage to the male reproductive system is particularly large, so young boys should be avoided.
Refrigerator
Refrigerator, to vacuum off the dust on the cooling pipes
Refrigerator running humming sound, the refrigerator back side or below the cooling lines release the magnetic field will be dozens or even hundreds of times higher than in front of the front (refrigerator before and after the scope of the measured 1 ~ 9mG, the back of the center of the can be as high as 300mG). If the efficiency of the refrigerator is not high, the humming sound is particularly long and loud, if you use a vacuum cleaner to vacuum the dust on the cooling lines, it will improve the efficiency of the refrigerator, but also reduce the magnetic field at home.
Computer LCD monitor radiation is smaller
If your computer desk is too small, forcing you to be too close to the screen, it may be worthwhile to place the monitor as far back as possible, and of course, switch to an LCD monitor, the radiation is quite small. As for the computer host, the general public is also easy to ignore and often placed in the leg side of the position, in order to facilitate the insertion of disks. The magnetic field in front of the host can be more than 4mG, the higher the magnetic field against the back of the higher, so you can put a little farther away to try to put a little farther away. There are often a bunch of wires and transformers underneath computer desks, so keep them as far away from your feet as possible.
Maintaining distance from cell phone chargers
Low-voltage power supplies with transformers generally have very high magnetic fields, and can measure more than 300mG at the place where they are wired, but they immediately fall below 1mG when they are only 30 centimeters away. Cell phone chargers, portable stand-alone players in the socket transformer magnetic field is also high, so keep the distance for health.
At the same time, but also pay attention to the following points:
1. In the placement of household appliances, do not place household appliances too centralized or often used together, especially TV sets, computers, refrigerators should not be placed centrally in the bedroom, so as to avoid exposing themselves to the risk of overdose radiation.
2. When electrical appliances are suspended, it is best not to let them in standby mode, because this time can produce a weak electromagnetic field.
3. Patients wearing pacemakers, as well as pregnant women, children and the elderly with weak resistance, should be equipped with shielding suits that block electromagnetic radiation.
4. Cell phone connecting the moment of the release of electromagnetic radiation is the largest, it is best to answer the phone in the cell phone ringing over a second or two, or the phone between the two ringing in the middle of the phone.
Prevention methods:
Television, computer dust, many people think, this is just a health problem. The fact is not so simple. Research has proved that dust is an important carrier of electromagnetic radiation. If your appliances are not wiped down often, then, even if they are turned off, electromagnetic radiation remains in the dust and continues to be harmful to your health.
Some appliances that use video as the end display, such as televisions and computers, are particularly effective in this regard. The monitors of these appliances are particularly susceptible to dust adsorption, and if they are not wiped in a timely manner, electromagnetic radiation will be retained in the dust, and with the dust in the indoor air diffusion, it is easy to be adsorbed by the human body's skin, and even with the respiratory tract into the body, and over time it will have an adverse effect on health.
The human body is also a conductor of electricity, electromagnetic radiation to the human body, the same will produce electromagnetic induction, and part of the energy deposition, ultimately leading to abnormalities in the function of human cells and cellular state, changing the electrical conduction of nerve cells, disrupting the normal physiological activities of human beings, and over time will also result in a neurasthenia and neurological disorders. Therefore, with the display of electrical appliances, it is best to wipe often, remove the dust at the same time, but also to stay in the inside of the electromagnetic radiation and clear away, can effectively prevent the radiation on the health hazards.
Home appliances on the dust more, but also bring other environmental pollution and security risks. Color TV dust contains a carcinogen called brominated dibenzofuran. Experiments have proved that the TV set for 3 consecutive days without rubbing, this carcinogen in the air content will rise sharply. Dust can also cause electronic components, circuit boards and radiators to be frequently overloaded, which ultimately leads to an increase in power consumption and can even burn out electronic components and cause fires.
The correct way to remove dust should follow these steps: When cleaning the exterior of an appliance, first unplug it from the power source for safety. When wiping the monitor's fluorescent screen, use a special cleaner and a clean, soft cloth, or use a cotton ball dipped in magnetic head cleaning solution. Many people in order to save trouble, with a wet cloth and even if, so that the surface looks clean, but some fingerprints, stains and crevices in the dust and dirt still remain on it. Finally, be sure to wipe again with a dry cloth, don't let the appliance stay in a wet state for a long time.
When cleaning the inside of an appliance, first make sure to disconnect the power for half an hour, then open the back cover of the monitor and use an electric hair dryer to blow out the dust that has accumulated inside. Then, scrub the circuit boards with anhydrous alcohol cotton balls, gently wipe the internal wiring with a dry cloth ball, and finally blow dry with an electric hair dryer. If you have the conditions, it is best to hire a professional mechanic to clean it to avoid safety problems
