When people use mobile phones, they will send radio waves to the transmitting base station, and the human body will absorb these radio waves more or less. These radio waves are the radiation of mobile phones. Generally speaking, mobile phones radiate less when they are in standby and more when they are talking. When the mobile phone number is dialed but not connected, the radiation is the largest, and the radiation amount is about three times that of standby. These radiations may change human tissues and adversely affect human health. "Radiation equals cooking the brain." British scholars once did an experiment. They put their mobile phones in the incubator of nematodes. After a period of electromagnetic radiation from mobile phones, they found that nematodes were just like boiled water. Professor Li said: "Although the skull can shield some microwaves, electromagnetic radiation has a strong penetrating power. The microwave penetrates the skull and acts on the brain, which is equivalent to cooking the brain. " Studies have confirmed that when using a mobile phone, 40% to 60% of the radiation will directly penetrate to the depth of one inch to one and a half inches, and the radiation from the mobile phone will accumulate in the brain. Professor Li briefly introduced the pathogenesis of brain tumor caused by cell phone radiation: brain cells are composed of neurons and glial cells, which will die when heated by radiation, and then glial cells will proliferate. If a part of the proliferated glial cells is abnormal, that part is canceration. When I was in college, Professor Li Anmin's internship was under the TV tower in this city. At that time, more than 200 students in the whole grade could not sleep at night, and returned to normal as soon as they got out of that environment. Everyone thinks it's strange. The TV tower will produce electromagnetic radiation to the surrounding environment, but the amount of radiation is different. Professor Li explained in a popular way: "People's brain cells are quiet at night, but if something keeps shaking, people can't sleep." Can cell phone radiation cause brain tumor? How harmful is the electromagnetic radiation of mobile phones? Professor Wang Sheng, who has been engaged in electromagnetic radiation research for a long time, believes that there is no scientific method to prove that brain tumors are caused by electromagnetic radiation, but it is internationally recognized that electromagnetic radiation is harmful to human body if it exceeds a certain intensity and lasts for a certain period of time. Researchers from the Institute of Environmental Health Monitoring, Chinese Academy of Preventive Medicine conducted a survey of more than 0 employees in 100 company, and found that using mobile phones can lead to adverse reactions in the nervous system. For example, mobile phone users and non-users are required to press keys at the same time to test their reactions. The average response time of mobile phone users is longer than that of non-users, and the number of correct responses is less. A "survey on the health impact of mobile phones" conducted by monitoring further shows that long-term use of mobile phones will cause chest tightness, nausea, loss of appetite and other adverse reactions, and at the same time have a negative impact on sleep quality. Using mobile phone for too long every day will cause many dreams and may also lead to insomnia. Many reports at home and abroad believe that the common phenomenon caused by electromagnetic radiation of mobile phones is neurasthenia, and the main symptoms are headache, dizziness, memory loss and inattention. Hanging a mobile phone around your waist can lead to infertility? ! Wu, an attending physician of infertility in Taipei Peace Hospital of China Computer News, pointed out that if the mobile phone is often hung on the waist or abdomen of the human body, the electromagnetic waves generated when it receives and sends signals will radiate to the sperm and eggs in the body, which may affect the user's reproductive function. According to media reports in Taiwan Province Province, Wu pointed out that the electromagnetic waves emitted by mobile phones belong to microwaves, similar to those emitted by microwave ovens. Microwave ovens can cook and scorch meat. Although the microwave of mobile phone is not as strong as that of microwave oven, it will also cause harm if the human body is too close, especially at the moment when the mobile phone is about to be connected, the electromagnetic wave is the strongest and the most harmful. Although it will not "burn" the human body, the damage to sperm and eggs, which are tiny germ cells, may be unbearable. In the past four years, Wu has presided over the infertility clinic of Heping Hospital and found that almost all patients have the habit of using mobile phones. She suggested that mobile phone users should try to keep their mobile phones away from their waist and abdomen, such as not hanging them on their chests, waists or stuffing them in their coat pockets. Some men put their mobile phones in their pants pockets, which is the biggest threat to sperm, because the pants pockets are next to the testicles. Whether in the office, at home or in the car, it is best to put your mobile phone aside. Don't answer immediately after pressing the answer key. Wait 1 2 seconds before you answer. In Wu Shuo, although the harm of mobile phones to human body is not easy to measure, there are reports and papers on the harm of mobile phones to human body. The British experimental report pointed out that mice irradiated by mobile phone microwave for 5 minutes will cause DNA damage; If human sperm and eggs are irradiated by mobile phone microwave for a long time, the possibility of DNA lesions will not be ruled out, which will affect reproductive function. Cell phone radiation: more terrible than imagined. A new study shows that the influence of electromagnetic radiation released by mobile phones on brain cells is 20% higher than previously estimated. According to Xinhua News Agency, the research was conducted by the Department of Applied Physics of Compton University in Madrid. Professor Sebastian pointed out that the data obtained by the existing methods underestimated the impact of radiation on human tissues, because the model commonly used to measure SAR index of electromagnetic radiation is round, which is different from real human cells. This experiment proves that the intensity of electromagnetic field will be higher when using models with actual shapes similar to human cells, such as cylindrical and football-shaped cell models. The researchers measured the electromagnetic field intensity caused by mobile phones through cylindrical, olive and spherical cell models respectively. The results show that the electromagnetic field intensity in cylindrical and ellipsoidal models is 15% ~ 20% higher than that in spherical models. Sebastian said: "Because the intensity of electromagnetic field is greater than expected, the impact on health will increase accordingly. We estimate that the legacy of electromagnetic radiation will continue to accumulate. Ten to fifteen years later, it is likely that there will be more cancer cases caused by the popularity of mobile phones. " According to the Oriental Daily, a German study found for the first time that mobile phones may cause eye cancer, because researchers found that people who frequently use mobile phones are three times more likely to develop eye cancer than others. If this research result is further confirmed, it will inevitably lead to a large number of claims litigation. The radiation released by mobile phones has long been accused of temporarily changing the function of brain cells, but there has been no evidence that these radiation will harm human health for a long time. However, this study, led by Professor Shi Tangshou of the University of Essen in Germany, made an amazing discovery. When they investigated the eye cancer of uveal melanoma, they found that this kind of cancer was closely related to radiation. The British magazine Epidemiology, which claimed billions of pounds, quoted Shi as saying that they had sent investigators to collect detailed information about the daily use of mobile phones by 1 18 patients with uveal melanoma, and compared these information with 475 people who were not sick. It was found that patients with uveal melanoma used mobile phones more frequently than others. Although it is not clear how cell phone radiation causes cancer, at least we know that a lot of water in the eyeball will enhance the absorption of radiation. In addition, they also found that melanocytes in grape membranes will start to grow and accelerate division when exposed to microwave radiation. Because the "uveal melanoma" usually found in the iris layer and the fundus of retina was originally formed in melanocytes, the radiation emitted by mobile phones may have an impact on these cells. Once mobile phone users have genes that are more likely to cause cancer, they will get cancer under the induction of these radiations. Last year, the British government appointed a company to study the security of mobile phones. Therefore, there is no evidence that cell phones have anything to do with brain cancer or other diseases. However, last month, an American mobile phone company in which Vodafone owns 45% of the shares was collectively sued by users, claiming that they suffered from brain cancer and other diseases after using their mobile phones, and the compensation amount was as high as several billion pounds. Don't turn a blind eye to the harm of mobile phones. There are a thousand hamlets in the eyes of a thousand people. A few days ago, this newspaper forwarded a picture of Xinhua News Agency. In the picture, a four-year-old boy is talking about mobile phones, which means that mobile phones in Shanghai are close to popularization. However, Mr. Xie, a physics professor at Jiamusi University, rushed to the newspaper for this purpose. Professor Xie said, beware of mobile phone radiation, especially children. Professor Xie believes that the current controversy about the radiation hazards of mobile phones is actually a discussion of quantity, not a question of existence. Professor Xie said that it is irresponsible for some media to unilaterally report that "mobile phones are harmless to health" in pursuit of being different. Professor Xie analyzed that the harm of mobile phone radiation to human body can be understood from the well-known law of conservation of energy. Mobile phones radiate microwaves, the essence of which is the transmission of energy. These microwave energies have strong penetrating power. When they enter human organs, according to the law of conservation of energy, they will not be destroyed. They will transfer this energy to human organs and convert it into other forms of energy: thermogenic and non-thermogenic. Professor Xie explained some vague understandings of people. People invented the microwave oven according to the heating effect of microwave. Some people will confidently say, "I don't see anyone's brain being microwave-cooked by a mobile phone!" " "Professor Xie explained that this is due to the different strength. However, because the mobile phone is close to the head when used, the microwave emitted is very concentrated, so repeated use of the mobile phone for a long time will definitely cause local lesions. Reports of eye cancer and brain cancer caused by mobile phone radiation are not uncommon. It is worth mentioning that the latest issue of the European Journal of Cancer Prevention published an expert's research report on 16 17 brain cancer patients. People who use mobile phones for a long time are 80% more likely than those who don't. Some people even say, "I have used my mobile phone for so many years, and nothing has happened." "Gabe, a scientist who studies human brain nerve cells at the University of London, pointed out that the incubation period of mobile phones is long, and it is difficult for people to see its harm at once, which makes many people turn a deaf ear to the harm of using mobile phones. A large number of scientific research results show that the part of microwave energy converted into non-thermal effect is more harmful to human body. The experimental report in Britain pointed out that using mobile phone microwave to irradiate mice for five minutes will produce DNA lesions, and the harm to human beings can be imagined. In view of the knowledge that mobile phone radiation is harmful to human body, all countries in the world have formulated the radiation safety standards for mobile phones, and the British government explicitly prohibits minors under 16 from using mobile phones; The Japanese government stipulates that mobile phones must be sold together with mobile phone radiation protection devices. There are nearly 200 million mobile phone users in China, and a considerable number of mobile phones have serious radiation. In order to protect the health of hundreds of millions of people, Professor Xie called on the relevant government departments to promulgate China's mobile phone radiation safety standards as soon as possible and implement them conscientiously.
