The harm of mobile phone radiation to human health is a serious social problem that exists objectively. It will not disappear just because the mobile phone industry deliberately conceals and avoids it.
At present, the world has begun to pay attention to the problem of mobile phone radiation, and is repeatedly "considering" the technical standards related to radiation. However, it is a pity that compared with the global popularity of mobile phones and the health of consumers, this slow progress It is already too late to "deliberate", and we have reason to believe that this procrastination will continue in many countries. Therefore, what is sad is not the lack of technical standards for mobile phone radiation, but the lack of a mechanism to deal with this impact on public safety and interests.
The era of globalization is an era in which multinational companies dominate the global economy. The influence of large companies goes far beyond the economic scope. They have become a power system that affects the operation of society. For issues like mobile phone radiation, large companies have actually violated the rights of the public by avoiding industrial privacy.
Social public health should be regarded as a public product. For example, when many companies are polluting the air, the guardian of the coordination of such public products should be the government. .
Mobile phone radiation is also harmful to public health. We cannot avoid the existence of radiation just because we cannot see it. Because the development of society cannot be completely equated with the development of corporate groups, but the development of the entire population. Regarding the issue of mobile phone radiation, governments of various countries have the responsibility to accelerate research on the radiation problem and provide symmetrical radiation information to the public; they also have the responsibility to set strict standards for enterprises, so that enterprises can assume more responsibilities to the people, and establish both service and Dual responsibility to society and profit. Therefore, mobile phone radiation is not terrible. What is terrible is that the international community has not established a rapid coordination mechanism to prevent similar problems from recurring.
While modern civilization has brought people a wealth of products and services, it has also caused people to fall into "happiness troubles": with the increase in the frequency of mobile phone use, health and safety issues caused by mobile phone radiation have become a major concern in the industry. focus of attention.
What is mobile phone radiation?
Research shows that when people use mobile phones, the mobile phones will transmit radio waves to the transmitting base station, and any kind of radio waves will be more or less absorbed by the human body. , thereby changing human tissue, and may also have an impact on human health. These radio waves are called mobile phone radiation.
In fact, it is more reasonable to call mobile phone radiation exposure, because the frequency used by mobile phones is between 800 and 1800MHz, which is completely different from ionizing radiation such as X-rays or gamma rays. It cannot be absorbed into the human body Produces ionizing or radiant energy, so it is called a non-ionizing radiation field.
The international scientific community has a relatively complete set of measurement standards for the size of mobile phone radiation, which is the so-called SAR value. SAR is the abbreviation of Specific Absorption Rate, which is also called the electromagnetic radiation test value. In layman’s terms, it is the impact of mobile phone radiation on the human body.
In 1990, the International Institute of Electrical and Electronics Engineers (IEEE) formulated technical standards for measuring electromagnetic radiation from mobile phones. In 1998, the International Commission on Non-Ionizing Radiation Protection (ICNIRP) also formulated similar technical standards, in which SAR is used to measure the electromagnetic radiation of mobile phones.
ICNIRP standards are recommended by the International Telecommunication Union and the International Health Organization and supported by most countries. In our country, the "Joint Working Group for the Development of National Standards for Electromagnetic Radiation", led by the General Administration of Quality Supervision, Inspection and Quarantine and jointly established with the Ministry of Health, the State Environmental Protection Administration, the Ministry of Information Industry, the State Administration of Radio, Film and Television, the State Grid Corporation of China and other units, is jointly formulating my country's electromagnetic radiation protection standards. standards, which also use SAR as the basic limit for measuring mobile phone radiation.
Mobile phone radiation is scarier than imagined
With the rapid increase in mobile phone ownership, people are paying more and more attention to the health and safety issues that may be caused by mobile phone radiation. However, most current mobile phone users still have an incomplete understanding of mobile phone radiation, and more and more scientific studies have shown that the harm caused by mobile phone radiation is far more terrifying than imagined.
Although there is still controversy in academic circles about mobile phone radiation, it is undeniable that it can cause harm to the human body under certain conditions.
A study organized by Professor Sebastian, head of the Department of Applied Physics at the Complutense University in Madrid, Spain, showed that the data obtained by existing methods clearly underestimated the impact of radiation on human tissues. Influence.
Sebastian said: "Since the intensity of the electromagnetic field is greater than expected, the impact on health will be correspondingly greater. We estimate that the harm of electromagnetic radiation will continue to accumulate, and in 10 to 15 years, more causes will likely appear. Cases of illnesses caused by mobile phone use”
Dr. Gunhild Ofterder of the Norwegian University of Science and Technology and his colleagues conducted a questionnaire survey on 12,000 Swedes and 5,000 people at the same time. Questionnaire-style surveys were also conducted among Norwegians who use mobile phones at work. As a result, 7803 people from Sweden responded and 2828 people from Norway responded. Among Norwegians who took part in the survey, 31% experienced at least one condition, while among Swedes 13% experienced one or more conditions. This research report also shows that headaches are most likely to occur within half an hour after making a phone call, and sometimes occur during the phone call. Many Norwegians say that the pain occurs when they are on the phone for more than 5 minutes. Many Swedes also say that symptoms will occur if they call for more than 5 minutes.
In our country, some researchers have also warned about mobile phone radiation. Xie Yichen, a professor of physics at Jiamusi University, believes that the current controversy about mobile phone radiation is actually just a discussion of quantity, not a question of presence or absence. Xie Yichen analyzed that the harm of mobile phone radiation to the human body can be understood from the well-known law of conservation of energy. Mobile phones mainly radiate microwaves through antennas. The essence of this radiation is the spread of energy. These microwave energies have strong penetrating power. When they enter human organs, they will not perish according to the law of conservation of energy. They will transfer this energy It is transferred to human organs and converted into other forms of energy, that is, producing thermal and non-thermal effects.
Xie Yichen believes that because the mobile phone antenna is close to the head when used, the microwaves emitted are very concentrated, so using the mobile phone for a long time will definitely cause local lesions.
Treat mobile phone radiation scientifically
In recent years, researchers have been trying to figure out whether mobile phone radiation will affect human health, but the research results are difficult to be recognized by all scientific communities. At the same time, research results on cell phone radiation are also mixed. In this regard, relevant Russian experts pointed out that this is due to different research methods.
Experts from Moscow Medical College wrote in the Russian magazine "Chemistry and Life" that there are roughly three reasons for these differences: First, many scientific research groups use different research methods, so researchers cannot analyze these groups. The data obtained are compared; secondly, the short observation period is another shortcoming of this type of study. The development process of some lesions suspected to be related to mobile phones is quite long, and it is difficult to determine the relationship between some early lesions and mobile phones using existing methods; 3. Some research activities may be affected by investors.
Although the industry has not yet reached an accurate conclusion on the extent of the harm caused by mobile phone radiation, experts suggest that it is best not to wait until the harmful effects of mobile phone radiation are fully confirmed before taking preventive measures. Stuart, chairman of the British National Radiation Protection Safety Committee, once warned that regarding mobile phone technology, our committee is very concerned about its impact on public health. Although mobile phones have become a part of daily life and even become a fashionable decoration for some people, just because everyone uses them does not mean that they are safe. Ms. Marlene, the head of the German Consumers Association, believes that the most important thing at present is to give consumers a control standard for mobile phone radiation.
Mobile phones are a new type of communication tool commonly used in modern people's lives and work. With the development of science and technology and the improvement of living standards, mobile phones have become more and more important and their popularity has become more and more widespread. Therefore, countries around the world are paying special attention to the increasingly serious mobile phone radiation, and have formulated relevant laws and regulations to control the mobile phone radiation environment. Scientists and researchers in various countries are also actively exploring the harm caused by mobile phones to human health, and are taking corresponding measures to eliminate this impact. Take Germany as an example. As early as July 2001, the German Environment Minister stated that the German government would strengthen the management of radiation generated by mobile communications and required that starting from the autumn of that year, mobile phone manufacturers must accurately indicate the degree of radiation in the user manual of the mobile phone.
Some mobile phone manufacturers are also very concerned about the problem of mobile phone radiation. Ning Shuyong, public relations director of Sony Ericsson (China), said that as a representative of high-end mobile phones, Sony Ericsson's mobile phone products have been implementing strict mobile phone radiation standards. All Sony Ericsson mobile phone products have radiation values ??marked on their manuals and product websites.
In addition, Ning Shuyong also revealed that Sony Ericsson has extracted a green substance from some vegetables for use in mobile phone manufacturing and is currently testing it. Haier, which has always been good at solving user problems, once again brought surprises to everyone. It is understood that some models of Haier mobile phones have successfully passed the mobile phone SAR value test of the State Environmental Protection Administration Certification Center (CEC), and the first batch has obtained Type II environmental label certification, effectively reducing radiation values ??and safeguarding the health of consumers.
Of course, many products have potential dangers for people. Questions such as whether mobile phone radiation will affect human health are not unexpected in the context of high technology rapidly changing human lifestyles. , the key to the problem is to use a scientific attitude to solve technical problems, which should be the rational thinking of human beings to correctly treat mobile phone radiation. In other words, humans should neither abandon civilization due to possible harm, nor should they ignore it; instead, they should pay appropriate attention to various processes such as research and development, use, and management.
