Radiation of electrical radiation
mobile phone in the standby state also has electromagnetic radiation. Experts believe that the phone placed in the pocket or hanging on the belt, will not affect human health.
In addition, according to the recent China Environmental Monitoring Center announced the indoor appliance radiation rankings, seven commonly used appliances, the microwave ranked first, more than twice the national standard of radiation. When is the maximum mobile phone radiation? By the Chinese Consumers Association and the China Institute of Metrology jointly commissioned by the China Institute of Metrology found that the phone in the call out with the initial contact with the network within a few seconds, the largest electromagnetic radiation, the first ring after the ring, the radiation gradually reduced The The test results also show that CDMA radiation is significantly less than GSM; built-in antenna is smaller than the external antenna, but the built-in antenna phone back electromagnetic radiation than the front plate several times;
Speaking of household appliances radiation, people will be on the computer, television and other large appliances have been vigilant, but can not think of hair dryer such a small appliance radiation greater. According to the measurement, the general household 1000W hair dryer, radiation value of up to 350mG or so (mG: millis is the magnetic field strength unit), far higher than the TV (about 45mG) and computer monitors (100mG) radiation value. Hair dryer in the open and closed when the radiation is the largest, so the switch as far as possible away from the head; use as far as possible with the head to keep vertical; but also to avoid prolonged use.
