Does the mobile phone have radiation?

In fact, the mobile phone itself will not endanger human health, and the culprit is the radiation released by the mobile phone.

Professor Zhao Yufeng, a senior expert in electromagnetic environment and a member of the Indoor Environment Monitoring Committee of China Interior Decoration Association, pointed out that when people use their mobile phones, they will send radio waves to the transmitting base station, and these radio waves will be absorbed by the human body more or less. These radio waves are the radiation of mobile phones, followed by antennas, receivers, keyboards and microphones. The radiation of mobile phones mainly comes from antennas, including external antennas and internal antennas. The intensity of radiation is inversely proportional to the distance between the mobile phone and the human body. The distance is doubled, and the radiation is attenuated ten times. Double the distance and increase the radiation intensity tenfold. In addition, from the position of the antenna, the radiation of the external antenna is larger than that of the internal antenna. The antenna of the straight board machine is closest to the head, so it radiates the most, and the antenna of the flip machine is farthest from the head, so it radiates less, and the slide machine is in between. But the function of the mobile phone has no effect on the radiation intensity. The latest issue of the American magazine "Dan Raft Grain Measuring Drum-State Super Card Please Yourself" teaches you how to minimize the radiation damage of mobile phones. 1. Use headphones. Although using headphones can't directly "destroy" radiation, it can isolate the human body from the radiation source. The farther the mobile phone is from the head, the less the brain is affected by radiation. The farther away from the antenna of the mobile phone, the lower the radiation the body receives. 2. texting is less radiation than calling. Short message communication can greatly reduce the radiation of mobile phones in contact with the head and body. Don't put your mobile phone between your legs when a man sends a text message. A large number of studies show that cell phone radiation can damage sperm motility, but it has little effect on female ovaries. 3. Always change hands on the phone. When talking on a mobile phone for a long time, it is best to alternate your left and right hands frequently. 4. Don't use your mobile phone in a closed space. Don't use mobile phones in relatively closed spaces such as elevators, trains and subways. At this time, the mobile phone keeps trying to connect the interrupted signal, which will maximize the radiation. Don't use your mobile phone when the signal is weak. When the signal is weak, or in a high-speed vehicle, the radiation generated by the mobile phone will be stronger. 6. Don't make phone calls. For a long call, it is best to use a landline. It is found that after talking on a mobile phone for 2 minutes, the brain waves will be affected by 1 hour at least. 7. Smartphones radiate a lot. Smart phones have built-in wireless devices, which generate stronger radiation than mobile phones, because these devices are mainly driven by batteries to receive emails, surf the Internet and so on. Therefore, use your mobile phone to surf the Internet as little as possible. 8. After dialing, stretch your arms. The radiation generated at the moment when the mobile phone is connected is the strongest, so after answering or dialing the mobile phone, it is best to stretch your arm and keep the mobile phone away from your body, and then talk later. 9. Don't put your mobile phone in your trouser pocket. The study found that men who often put their mobile phones in their trouser pockets have 25% less sperm than normal men. Mobile phone radiation has different effects on different parts of the body, and male testicles are most vulnerable to mobile phone radiation. 10. Don't bring your mobile phone into the bedroom. Don't put your mobile phone on the pillow when you sleep. Radiation will reduce the secretion of melatonin, which will not only affect the quality of sleep, but also accelerate the destruction of human free radicals, eventually leading to diseases such as cancer.
