With the development of science, people's lives have made great progress, but the high-tech in life will also bring harm to us. <br><br>Mobile phones, everyone knows it. Mobile phones have brought convenience to people's lives, but everything has advantages and disadvantages, and the harm caused by mobile phones to people even exceeds that of smoking. <br><br>When people use a mobile phone, the mobile phone transmits radio waves to the transmitting base station, and the radio waves are more or less absorbed by the human body. These radio waves are radiation from the mobile phone. Generally speaking, the radiation of the mobile phone is less when it is in standby, and the radiation is larger during a call, and when the mobile phone number has been dialed but not connected, the radiation is the largest, and the radiation amount is about 3 times that of the standby. These radiations may change human tissues and cause adverse effects on human health.

Generally speaking, mobile phone standby radiation is smaller, radiation during the call is larger, and when the mobile phone number has been dialed out and has not yet been connected, the radiation is the largest, the amount of radiation is about 3 times the amount of standby. These radiations have the potential to alter human tissues and adversely affect human health.
