Sitting in the car, using the mobile phone when there is no electricity, the radiation is also very strong
Nowadays, the role of mobile phones in this information society is becoming more and more important. And the saying that mobile phones are harmful to health is also ” endless”. Despite this, people’s dependence on mobile phones is still growing. In fact, when we use the phone, we can minimize this damage with a little attention.
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 mobile phone radiation. Gao Xiaogang, a professor at the China Radio Branch of the International Committee for Radiological Noise and Interference, pointed out that many people have a lot of misunderstandings when using mobile phones. For example, when they use mobile phones, they always like to walk around and answer calls in the corner. Frequent moving of the position will cause the signal strength of the mobile phone to rise and fall, and the mobile phone always transmits radio waves to the transmitting station, increasing the amount of radiation of the mobile phone. When using a mobile phone in a corner, the signal is poor, which increases the power of the hand, resulting in an increase in radiation intensity. For the same reason, using a mobile phone in a small, enclosed environment such as an elevator will also increase its radiation intensity.
For the safety of mobile phones, Dr. Ronald · Hepman of the University of Pittsburgh recently gave several suggestions.
1. When talking, keep the phone at least 5 cm away from your body. Because the intensity of the electromagnetic field amplitude of the mobile phone is 1/4 of the original value 5 cm away from the body, and its strength is only 1/50 of the original 9 cm away from the body. It is therefore best to use a speaker or earphone. In both cases, the phone radiation is only 1/100 of the standard phone.
2. If you must carry your mobile phone, make sure that the keypad is facing the body and the back is facing the outside of the body. In this way, the transmitted electromagnetic field can be kept away from your body.
3. When talking, change the body orientation regularly. This will distract the radiation that the body is exposed to. In addition, when the other party picks up the phone, put the phone on the ear to reduce the radiation released by the electromagnetic field.
4. In addition to not going back and forth, playing mobile phones, you should try to avoid using mobile phones in cars or trains. Because the phone constantly tries to connect to the interrupted signal, the radiation is increased to the maximum.
5. Send more text messages and make fewer calls. This will reduce the contact time between the phone and the head.
6. When sleeping, don’t put your phone next to the pillow. Pregnant women should not use a mobile phone.
7. When the phone is running out of power, it is best not to call when charging.
