Cell phones have harmful radiation. Most people who have studied physics have a certain cognitive ability. Everything in the world except absolute zero has heat value, and it is thermal radiation that spreads heat value. Radiation is an object that spreads kinetic energy outward according to the method of releasing radio waves or particles. In the natural environment of our daily life, radiation is everywhere. Generally speaking, as long as the compressive strength of radiation is enough, it will affect the electronic devices in molecules. This kind of radiation is called hydrolytic radiation, which always occurs in radioactive substances, nuclear reactors, nuclear bombs and other corrosive chemicals.
We usually talk about ultraviolet rays, infrared induction, light sources, radio waves and microwave heating caused by household appliances. The radiation emitted by mobile phones is radio wave radiation and belongs to non-hydrolytic radiation. Many people may have heard that mobile phones have radiation, and they may gradually worry that they can't leave their mobile phones for 24 hours without realizing the risks. In fact, don't worry too much, because cell phone radiation won't cause cancer.
Can cell phone radiation cause cancer? NTP, a subsidiary of China Institute of Hygiene and Hygiene, published the large-scale scientific research data of small animals on mobile phone magnetic induction radiation (RFR) so far, and found that there is a correlation between mobile phone radiation and cancer risk. However, in many subsequent scientific studies, many results were contrary. Most biologists think that even if the magnetic induction radiation exposed in daily life has any impact on physical and mental health, the impact is smaller than other common injuries, so there is no need to worry too much.
Moreover, the frequency of electromagnetic waves of mobile phones ranges from 3KHz to 300GHz, which is far less than the radiation generated by visible light. From the point of kinetic energy, the light with the least visible light frequency is colored light, with the frequency of 10- 14HZ, and the mobile phone with a higher radiation frequency is generally 300GHZ. In other words, the frequency of colored light with weak kinetic energy in visible light is 300 times that of the mobile phone with the largest output power. Calculate that the compressive strength of the kinetic energy of radio wave radiation that everyone suffers in the sun every day is much stronger than the radiation generated by mobile phones. So don't worry about the problem that cell phones can cause cancer. After all, there is no carcinogenic system. But long-term use of mobile phones will also cause some other physical and mental health harm to everyone's body!
The harm of mobile phone to physical and mental health 1, affecting mentality: mobile dating software, a lot of information content will make everyone get carried away in it, which will make people feel depressed and tired for a long time, and their mentality will also decline. And there is a sense of "dependence". If you don't play for a while, you will feel confused, which will greatly affect people's beliefs.
2, eye vision decline: long-term staring at the mobile phone display has a great impact on preventing myopia, eyes are prone to fatigue, blurred vision.
3, spinal injury: long-term low head playing with mobile phones, it is easy to cause lumbar muscle spasm, cervical spine and intervertebral disc physiological curvature changes.
4, causing hemorrhoids constipation: Many people often play with their mobile phones when urinating. This kind of personal behavior will inadvertently cause poor stool, which will easily lead to hemorrhoids constipation in the long run.
5, affecting the quality of sleep: Many people have the habit of playing mobile phones before going to bed, but playing mobile phones before going to bed will cause physical or psychological excitement, and turning off the lights, the light source caused by mobile phones will also inhibit the metabolism of insomnia drugs, which is very easy to cause insomnia and sleep decline!
Finally, although mobile phone radiation belongs to non-hydrolytic radiation, it is necessary to pay attention to mobile phones at all times, and the accumulation of time is likely to increase the impact of radiation on the body. In addition, looking down at the mobile phone for a long time will hurt the cervical spine, playing with the mobile phone in a semi-lying position will hurt the intervertebral disc, and excessive use of the mobile phone will continue to hurt the eyes. This kind of damage is even more serious than the radiation of mobile phones, so it should be noted that although mobile phones are good, they should be used moderately.
