Cell phones are designated as carcinogens.

Not long ago, the International Agency for Cancer Research (IARC), the World Health Organization (WHO), defined mobile phones as potentially carcinogenic items that were linked to gliomas (a brain tumor). It is also the first time that the WHO has made a characterization of cell phone radiation. For a time, people's attention to mobile phone radiation has reached an unprecedented level. The WHO estimates that there are 5 billion mobile subscribers around the world, as early as last year China's mobile phone users have exceeded 700 million. Mobile penetration is getting higher, and the controversy over the dangers of mobile phone radiation has not stopped. 2009, Sweden and a number of European countries found that using mobile phones for more than 10 years may increase the risk of brain cancer and oral cancer. Dutch studies show that cell phone radiation is closely related to insomnia, Alzheimer's disease, child behavior problems, male infertility, and so on. A British cancer expert concluded in March 2010 that the number of deaths from mobile phones would outweigh smoking. This is by far the most serious warning about the health hazards of mobile phones. Earlier this year, the French and German governments warned against excessive use of mobile phones, especially children. The cell phone was identified as a carcinogen, and many experts hold conservative opinions, said Ed Yong, head of health information at the Cancer Institute in the UK, which has not yet found the necessary link between mobile phones and cancer, and is not strong enough to prove it. The survey also found that the risk of brain tumors in people using mobile phones was similar to the risk of brain tumors without using a cell phone. Although cell phone cancer has so far remained at a possible level, the WHO decision suggests that there is a real link between mobile phones and cancer, and that it is important for long-term research to divide and discover the potential health consequences of cellphones. IARC in charge of Christopher Fu Walde said.

Senior electromagnetic environmental experts, China Interior Decoration Association Indoor Environmental Monitoring Work Committee Professor Zhao Yu pointed out that when people use mobile phones, the hand opportunity to transmit radio waves to the base station, and radio waves are more or less absorbed by the human body, these waves are mobile phone radiation, from high to low in sequence for the antenna, handset, keyboard and microphone department. The phone's radiation comes mainly from antennas, including external antennas and built-in antennas. The intensity of radiation is inversely proportional to the distance between the cell phone and the human body, the distance is one times, the radiation attenuation 10 times times, the distance is shortened by one times, the radiation intensity increases 10 times times. In addition, from the position of the antenna, the external antenna radiation than the built-in to larger. Straight machine antenna from the head recently, so it's the biggest radiation, flip machine antenna from the head farthest, so the radiation is small, the slider between the two. But the function of the handset is how many, have no influence to radiate intensity. In addition, the radiation volume of each cell phone is also different, CNN recently published the Mobile Phone radiation volume rankings. The figures in the table mean the amount of radiation per kilogram of body weight. Of course, these are estimates, and the actual amount of radiation absorbed depends on the use of methods, operators and the environment. The latest issue of the United States "Yue Self" magazine How to minimize radiation damage to your phone. 1. Headphones with headphones can not directly eliminate radiation, but the human body and radiation source isolation. The farther away the phone is from the head, the less radiation the brain is affected. The farther away the phone antenna is, the lower the amount of radiation the body receives. 2. Texting a small text message rather than making a phone call can greatly reduce the radiation exposure of the head and body. When men send text messages, do not put the phone between the legs. A large number of studies have shown that cell phone radiation can harm sperm motility, but has little effect on women's ovaries. 3. Phone often change leprous time to play mobile phone, the best hand often alternating. 4. Do not in the closed space to play mobile phones in elevators, trains, subways and other relatively closed space to play mobile phones. At this point the phone constantly try to connect the interrupted signal, will increase the radiation to the maximum value. 5. Don't hit the phone when the signal is weak when the signal is weak, or when the vehicle is running at a high speed, the radiation generated by the handset is stronger. 6. Don't use the phone to talk on the phone for a long time, preferably using a landline. The study found that after 2 minutes of cell phone calls, brain waves were affected for at least 1 hours. 7. Smartphones radiate larger smartphones with built-in wireless devices that produce more radiation than mobile phones because they are mainly battery-powered to receive e-mail, surf the internet, and so on. Therefore, as little as possible to use mobile phone Internet. 8. After dialing, stretch the arm mobile phone to produce the most radiation, so pick up or call the phone, it is best to stretch the arm, let the phone away from the body, wait a moment to call again. 9. Don't put your cell phone in your trouser pocket. Studies have found that men who often put their phones in trouser pockets are 25 less sperm than normal males.%。 Cell phone radiation on the body of different effects, male testicles are most vulnerable to cell phone radiation damage. 10. Don't put your cell phone on your pillow while you're sleeping in your bedroom. Radiation can reduce the amount of melatonin secretion, not only affect the quality of sleep, but also accelerate the destruction of human free radicals, resulting in cancer and other diseases occur.
