Since the beginning of the year, China's "green phone" the wind blowing strong. Subsequently, many experts said openly that "there is no green phone." This is how the matter in the end? In the end who is wrong? Consumers are confused.
Then, mobile phone radiation have any effect on the human body in the end? How to correctly understand the cell phone radiation and other issues? Consumers with issues of common concern, the author examined a large amount of information issued by authoritative bodies, and heard of Telecom Research Laboratory, deputy director of China Tyre, South of electromagnetic radiation testing expert Wang, Vice President of Tsinghua University, Telecom experts, scholars and other experts Gong Ke introduction of mobile phone radiation has some superficial understanding of the problem.
Standard, you can rest assured that the use
According to authoritative experts, at present on the cell phone radiation, there are many in the general public in the error, it was thought that cell phone radiation large, long-term use will cause injury. Is not the case. We use the phone, the main frequency of 900 trillion trillion and 1800, did not like the X-ray ionizing radiation produced, but not as terrible as nuclear radiation, cell phone radiation commonly referred to as non-ionizing radiation. Therefore, the experts hoped to Chinese, "Radiation" is changed to "RF radiation", this international standard format helps to reduce adverse psychological reactions of people to avoid the "radiation" and "nuclear radiation" link.
Secretary-General of the World Mobile Communication Forum
Mike emphasized that in the past 20 years, the world of mobile phone radiation on human health effects of experimental total of 289, but did not find the results of a scientific evidence of this.
2000, the Australian scientists have proposed the "heat shock" theory of cancer, this is the first mobile phone radiation and cancer linked to theory. But the American Cancer Society has a formal position in 2001: to be absorbed by human tissue cell phone radio waves because there is no ionizing radiation, and low energy can not cause cancer.
To 2001, the World Health Organization, the International Commission on Non-Ionizing Radiation Protection, the British mobile phone group of independent experts, the American Cancer Society and other international authoritative organizations have position: not found mobile phone radiation on biological effects.
Denmark has concluded a 13-year national study shows that: cell phones and brain tumors, leukemia, cancer link between the hypothesis does not hold. It is understood that the results of hundreds of thousands of local mobile phone users were tracked.
According to authoritative experts, in previous years have also been in the foreign lawsuit, the lawsuit eventually because of the medical profession can not prove that mobile phone radiation because of the damage but failed to hit down. Until now, no such case can be played together in the end of.
Any radio transmitting device will produce electromagnetic radiation, the environment we live there is radiation everywhere. The question is whether the radiation exceeds the standard, as long as does not exceed accepted safety standards, there is no human health effects. Like people do not hand in the boiling water, but will not hesitate to put his hand in warm water. The same applies to electromagnetic radiation.
Therefore, as a cell phone user, there should be a scientific concept: the standard is that the healthy, safe to use.
International harmonization of radiation safety indicators
Then display the amount of mobile phone radiation indicator of what an indicator how much is safe? This, international and domestic opinion is basically the same, that through the SAR value of such a concept to quantify cell phone radiation and measurement. The so-called SAR, is the abbreviation SpecificAbsorptionRate is uptake rate, simply, is in unit time per kg of the substance absorbed electromagnetic energy, the unit is W / kg.
Present, on the SAR safety standards in Europe is 2 W / kg, the United States is 1.6 watts / kg. In China, already by the State General Administration of Quality Supervision, Inspection and Quarantine of the lead, joint health, environmental protection, broadcasting, electricity, and completed the five ministries of information industry, "electromagnetic radiation exposure limits and measurement methods," the final draft of the national compulsory standards, the country is seeking opinion, which limits the mobile phone radiation standard is one watt / kg. To be sure, our final value issued by mobile phone radiation standard than the European standard and American standard more stringent, in order to effectively guarantee people's health and safety.
I am an expert from China Manufacturers, usually analyzes all kind of industries situation, such as current limiting fuses , fused disconnect.
