After answering the phone for a long time, the human body will be exposed to more radiation, and the brain will feel dizzy and nervous fatigue. The radiation of the mobile phone is small when it is in standby, but it is large when it is talking. When dialed but not connected, the radiation is the largest, and the amount is about 3 times that of standby. These radiations may have adverse effects on human health.
Health advice on using mobile phones:
1. When making a phone call, don't put your phone to your ear and shout "Hello" before dialing. You should wait a second or two before sticking it to your ear.
2. When turning on, turning off, texting or surfing the Internet, try to stay away from your head and increase the straight-line distance.
3. Call for a long time, use headphones as much as possible, or answer the phone alternately. At the same time, don't walk around at will, which will cause the strength of the received signal to fluctuate, thus causing unnecessary short-term high-power transmission.
4. Wearing headphones to make phone calls can reduce radiation. Although the use of headphones can not directly eliminate radiation, it can isolate the human body from the radiation source.
