How much do you know about the radiation hazards of mobile phones when you play with mobile phones frequently? Is there any scientific basis for the statement that the less the power of mobile phones is, the greater the radiation is? With the development of modern communication technology, mobile phones have become a part of our life. Let's look at the related knowledge about mobile phone radiation together. We can't do without mobile phones at least learn how to avoid or reduce the harm caused by mobile phone radiation.
Less electricity and more radiation?
In fact, the radiation intensity of mobile phone has nothing to do with electricity. When the signal intensity of mobile phone is weak, the radiation of mobile phone will be strengthened so as to receive more signals. If the signal is weak, will the radiation intensity of the mobile phone really be 1000 times of that in the legend? Take GSM mobile phone for example, when it works at 1800MHz, when the signal is weak, its maximum peak power can reach 1W, while when the signal is full, its minimum power is 1MW, with a difference of 1000 times.
Although the intensity of cell phone radiation will increase when the signal is weak, it is difficult to reach the peak value in actual use, which has little impact on health. However, the harm of cell phone radiation should not be underestimated. Try to avoid answering and making calls when the signal is weak, and try to use headphones when making calls to indirectly reduce cell phone radiation Harm.
How to avoid the harm of mobile phone radiation
1. When answering the phone, if you feel the heat on your head and face, stop the call immediately. Try not to keep the phone close to your body or ears when the phone is on or before and after connecting.
2. Use earphones as much as possible for a long time. The main radiation effect of mobile phones on the head is near-field radiation. The closer to mobile phones, the greater the radiation. Try to reduce the length of the call, not to talk on the phone.
3 do not answer or call when the signal of mobile phone is weak. Most mobile phones support Bluetooth function, and the use of Bluetooth headset can effectively reduce the radiation damage of mobile phone.
7. When charging the mobile phone, it's better to leave the socket 30 cm away from the human body. Do not put the mobile phone near the bed, especially when charging at night.
