Five mobile phones are used to receive the largest radiation.

1. private phone connectionFor phone calls involving private content, many people prefer to answer questions in the corner of a building. In general, the signal coverage in the corner of the building is relatively poor, so the radiation power of the mobile phone will increase to a certain extent. In the same way, when in a small and closed environment such as an elevator, you should also be careful when making a mobile phone call. 2. Being too "close" to mobile phones"When the phone signal gets weaker, many people will instinctively keep the phone as close as possible to their ears. However, according to the working principle of the mobile phone, when the signal is weak, the mobile phone will automatically increase the electromagnetic emission power, significantly increasing the radiation intensity. At this time, the ears are close to each other, and the radiation on the head will multiply. 3. dial the phone number close to your earsWhen the phone calls out but the phone is not connected, the radiation will obviously increase. At this time, the phone should be kept away from the head, and the call will be made after about five seconds. 4. Cell phone porridge with one ear potResearch shows that prolonged continuous radiation may affect the brain. Experts suggest that you should not use a mobile phone for a long time. You can use a fixed phone or headset. If you need to use a mobile phone for a long time, you should rotate your ears every one or two minutes. 5. frequent movementSome people prefer to walk around and do not consciously when making a cell phone, but do not know that frequent movement of the location will lead to ups and downs of reception signals, leading to unnecessary cell phone power enhancement. In addition, when you call a mobile phone on a driving vehicle, the mobile phone may provide services for high-power base stations with a wider coverage to avoid too frequent regional switching, the transmit power will increase as the transmission distance increases.
