The radiation range of the mobile phone is an annular belt centered on the mobile phone, and the distance between the mobile phone and the human body determines the degree to which the radiation is absorbed by the human body. Therefore, people need to keep their distance from their mobile phones.
How to use mobile phone correctly
1. It is best to keep away from the head when the mobile phone exhales to avoid radiation to the head when the mobile phone emits high power.
2. Try to reduce the time of using the mobile phone every time and the number of times of using the mobile phone every day. When you need to talk for a long time, it is more scientific to alternate left and right ears or use headphones.
3. When the cell phone signal becomes weak, the cell phone will automatically increase the transmission power of electromagnetic waves, so don't put your ear near the cell phone at this time.
