Teach you to easily self appliances a safe distance from the electromagnetic radiation.

<P> In our country "electromagnetic radiation protection", the clearly defined in the professional environment, electromagnetic radiation power density can not exceed 20uw / square centimeter; in life </ P> <P> in our country "electromagnetic radiation protection ."expressly provided for in the professional environment, electromagnetic radiation power density can not exceed 20uW / square centimeter; in the living environment, the electromagnetic radiation power density can not exceed 40uW / square centimeter. .Study confirmed that when the magnetic field to 2mG, the risk of starting double. .According to test data, in household appliances, microwave ovens, vacuum cleaners, mobile phones, the strongest electromagnetic radiation, can be reached 200MG (magnetic flux density in units of gigahertz, 20uW / sq cm is approximately equal to 2MG). .</ P> <P> want to know a safe distance from electric appliances, there is a simple self-test method. .Open the can receive AM (amplitude modulation) radio channel, the channel transfer in the absence of local broadcast, and to be measured close to the TV, refrigerator, microwave oven and other household appliances or computers, you will find the radio that the noise came abruptly. .Out some distance before they are returned to their original small amount of noise. .This distance is the distance of the electrical appliances, usually with the appliance to maintain a safe distance can be measured. .</ P>.
