What is cell phone radiation?
When people use mobile phones, mobile phones will send radio waves to the transmitting base station, and any kind of radio waves will be absorbed by the human body to a greater or lesser extent, thus changing human tissues and possibly affecting human health. These radio waves are called cell phone radiation.
What we often hear is the specific absorption rate of mobile phone SAR: SAR represents the allowable radiation absorbed by organisms (including human body) per unit kilogram. This SAR value represents the influence of radiation on human body and is the most direct test value. SAR has data of the whole body, parts and limbs. The lower the SAR value, the less radiation is absorbed. Among them, the standard SAR value of the brain part must be lower than1.67W to be safe. However, this does not mean that the SAR level is directly related to the health of mobile phone users.
The probability of getting eye cancer with a mobile phone is three times higher (Figure)

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 research, 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.
Claims amount to billions of pounds.
The British "Epidemiology" magazine quoted Shi Tangshou as saying that they had sent investigators to collect detailed information about the daily use of mobile phones from 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.
The theory of "mobile phone radiation" triggered the security panic in the century.

Enjoy Scientific and Technological Progress in Condoms —— The theory of "cell phone radiation" triggered the century security panic
It is said that Peter Angelos, an American lawyer who is famous for helping some American cigarette victims win huge compensation lawsuits, is planning to initiate a 10 claim lawsuit against mobile phone manufacturers, mobile network operators and fixed telephone companies on behalf of some American brain tumor patients. Verizon Wireless, the largest mobile communication operator in the United States, and Vodafone, the world's largest mobile phone provider with a 45% stake, will be the defendants in all the above lawsuits. This is the biggest lawsuit filed against the mobile phone industry so far, which has once again attracted attention to the theory of mobile phone radiation that has been inconclusive for several years, but no one can give consumers a clear explanation.
How much harm can mobile phone radiation do to human body has become a cross-century unsolved case, and no one can give a clear statement so far. Everyone knows that smoking is harmful to health, but there are still some people who are restless. When mobile communication has become the dependence of more and more people like cigarettes, people have fallen into a dilemma between health and convenience. However, the difference between mobile phones and cigarettes lies in where the danger lies, and people are still arguing ambitiously about where the danger lurks. This makes merchants always hang a sword on their heads, not knowing whether to drop it or remove it, which makes consumers panic. Known injuries can be prevented, and unknown fears are as worrying as the protagonist in The Man in the Condom.
Rumors are flying everywhere. Who should I trust?
Although scientific and technological progress has brought us great convenience, although it seems that we can't stand life without mobile phones, what's the point if we can't have health, wealth and achievements? Therefore, from the perspective of security, I don't know how much harm it does to people, making mobile phones the most concerned technology products. However, the rumors surrounding this issue are inconsistent, and people don't know who to trust.
It is the most popular saying that mobile phone radiation can induce brain tumors, and there have been many cases in which patients with brain tumors have brought mobile phone manufacturers to court. Although researchers have done a lot of experiments, it is a pity that this problem is still an unsolved mystery.
The latest news is that in the middle of last year, Swedish researchers said that there is a certain relationship between using mobile phones and brain tumors. This conclusion was made after investigating the relationship between brain tumor and cell phone use in 233 patients with brain tumors (including benign and malignant brain tumors) in two regions of Sweden by various methods. For example, a survey on which ear is used in the left ear and which ear is used in the right ear when using a mobile phone, and where the brain tumor occurs, shows that patients who frequently use mobile phones have a higher probability of developing tumors on the side of the brain than on the back, front and top of the brain.
However, a recent research report published in the Journal of the American Medical Association shows that cell phone use has nothing to do with brain tumors.
When there are more and more rumors that mobile phone radiation is harmful to human health, a new industry has emerged. The year before last, many domestic companies claimed that their products could reduce a lot of radiation, so for a while, people posted radiation protection products on various parts of mobile phones because of the publicity of various companies. It seems that this industry has not flourished. It gradually disappeared last year, but headphones became popular. Although the explanation of mobile phone manufacturers on whether mobile phone radiation is harmful to health is vague, their staff always insisted on using headphones to make calls at the earliest. People think that headphones can reduce the probability of radiation to some extent.
People haven't got inner peace for a long time. The British consumer research magazine "Which" also reported that using mobile phone headphones will cause users' brains to be irradiated by three times that of ordinary mobile phones. The article thinks that it is impossible to provide a "absolutely safe" way for mobile phone users to hold their mobile phones. The distance between the top of the antenna and the earphone is too long or too short, which will increase the radiation. Only when the distance reaches the optimal value can the radiation be reduced, but who knows where the optimal value is. The magazine suggested that wrapping the earphone cable of a mobile phone with a metal or ceramic shell may help reduce the radiation to the ears of mobile phone users.
There are many such examples, the first one draws a conclusion, the second one denies it, and more hazards are constantly being discovered. American researchers say that cell phone radiation can change human genes. Although this report can't prove that cell phone radiation can destroy DNA, some experiments show that these radiation can cause genetic changes in human blood cells. A British expert also warned that mobile phones may release toxic mercury gas, causing damage to the brain; More and more terrible things may be confirmed by scientists, such as inducing Alzheimer's disease, Parkinson's disease, multiple sclerosis, endangering fertility, premature aging and amnesia.
Although some mobile phone manufacturers have begun to disclose their test results of various mobile phone radiation levels to consumers, and experts have constantly put forward preventive suggestions, people don't know who to trust because of the contradictory explanations of mobile phone radiation by government agencies or media in various countries so far.
That's it. Although there is no medical evidence that cell phone radiation can cause cancer or other diseases, there is no evidence that cell phone radiation is harmless to human body.
When will the radiation of mobile phones be finally determined?
Mobile phones have existed for so many years. What people can't understand is that the ever-changing high technology makes all kinds of models and functions constantly updated, but it can't do anything about the radiation of mobile phones. When we can't give up using mobile phones, when will the radiation of mobile phones be finalized?
In fact, the most important thing now is to give consumers a standard in the radiation control of mobile phones. But at present, the standards used by countries all over the world are different, including European standards, American standards and the standards of the former Soviet Union. All manufacturers claim that their products are controlled by standards. Last year, the relevant departments in China reported that it was possible for China to promulgate relevant standards within this year. Regrettably, no relevant standards have been issued so far.
Under the support of various standards, mobile phone manufacturers and telecom experts believe that using mobile phones will not endanger human health. People in this camp insist that the electromagnetic radiation energy produced by mobile phones is different from the strong electromagnetic wave energy produced by X-rays and nuclear radiation, which destroys the molecular structure of human cells and DNA, damages human white blood cells and induces cancer. When a mobile phone is talking, electromagnetic waves will cause vibration and heat, but this temperature rise phenomenon is also quite small and safe.
However, many experts in biology, medicine and environmental protection believe that mobile phones are harmful to health. Their point of view is that in order to realize the communication function, the mobile phone must keep in touch with the transmitting base station, and it must receive and send powerful communication waves. The strongest part of the radio wave is the top of the mobile phone antenna. In the process of using the mobile phone, the antenna is just closest to the brain, so it will definitely have a negative impact on the human brain.
The topic between mobile phones and human health has always been confusing. Up to now, almost all the related studies can't reach the final conclusion whether using mobile phones will harm human health. Even the World Health Organization has not provided evidence that mobile phones are harmful to health, so it has always stressed that the current scientific information does not show the need to take any special protective measures against the use of mobile phones. It is said that the World Health Organization predicts whether the radiation generated by mobile phones and their terminals will increase the risk of cancer in people's head or neck, and it will take three to four years to investigate and study, but how many four years can life wait to reach this conclusion?
As for the disadvantages of using mobile phones, the only thing that can be determined at present is that it is dangerous to drive and make phone calls. Therefore, the only thing people can do before knowing whether using the mobile phone will still cause danger to themselves is to minimize the talk time, stay away from it or take preventive measures that you think are effective, at least to give themselves psychological comfort.
Will the radiation problem of mobile phones trigger an industry crisis?
It is difficult to accurately predict whether this problem will cause a crisis to the whole industry when the debate on mobile phone radiation is always shrouded in clouds, but no matter how harmful things are, as long as there is demand, they can form a prosperous scene. Drugs are like this, especially cigarettes. Whether mobile phones are harmful to health has always been difficult to draw a conclusion, and the mobile phone industry seems to be even less worried.
However, the news that Vodafone will be involved in the 10 lawsuit caused its share price to fall to its lowest point this year after the news was announced. It is said that Vodafone and BT lost 5 billion pounds on the same day. Although no defendant has won a similar lawsuit yet, if Angelos wins this lawsuit, it is likely to cause a domino effect on a global scale. Not only will the share prices of major mobile phone companies plummet, but the mobile phone industry is more likely to be hit hard.
I don't know if it's because the problem of mobile phone radiation has been debated for too long and too much. Many consumers have many questions about the manufacturer. No matter how many manufacturers insist that their products are under standard control, there are still some consumers who think that the harm of mobile phone radiation to human body should be predicted, because until now, no company has dared to stand up and deny the connection between mobile phone and brain tumor. They just keep claiming that their products meet the relevant standards. It is said that some American lawyers, including Angelo, hope that the court will allow them to consult the relevant documents of mobile phone companies. They think that by consulting these documents, they may find some evidence that mobile phones may cause brain tumors. Not only that, some consumers also believe that since manufacturers have the ability to make such high-tech gadgets affect people's lives, they are fully capable of reducing the radiation to the human body by changing the design of mobile phones. Why don't you do that? That can only be understood from the commercial motives of manufacturers.
Whether the radiation of mobile phones is harmful to human health, there are indeed many places where it is difficult to draw conclusions, which has also buried many hidden dangers for manufacturers. The longer this question is debated, the more arguments there will be. Once there is a case to support the "harmful theory", the situation of manufacturers and operators will be out of control.
In fact, many products are potentially dangerous to people, not because people have too high demands on mobile phones, but because people are surrounded by more and more high-tech products and feel an anxiety that cannot be grasped.
