June 29, 2009, Italy, A Player To Participate In Mobile Phone Throwing Contest.
The phone is cancer, after the mainstream view is that there is not enough evidence to show an association between the two, however, the World Health Organization recently released an assessment of the report, "mobile phone may be carcinogenic," which is the field of mobile phone radiation affect human health, the most authoritative assessment of the report, however, this is a non-conclusive assessment of the radio industry has aroused the ridicule, but also to the debate on this issue to upgrade again.
May 24 to 31, Lyon, France, from 14 countries, 31 scientists gathered at the World Health Organization attributed to IARC (IARC) meeting room, the scientific community over the years and made mobile phone cancer Relationship between evaluation.
May 31, Jonathan Smith, chief scientist of the working group said in a statement Germany, from the current collection of evidence to conclude --- with some mobile phones may cause cancer.
Scientists use the phone eventually included in the "likely carcinogen" in the category. This classification means that there is some evidence that it will lead to human cancer, but far from the "summary" with it, require further study.
IARC carcinogens into five categories will, in addition to "probably carcinogenic," but also including cancer, is likely to cause cancer, is unknown, it may not cause cancer. Among them, smoking and passive smoking have been included in the "definitely cancer", "likely carcinogen," including the production of art glass and used hair dryer to the barber and other professional behavior, use the phone belongs to a "potentially carcinogenic" on the row in the behind.
The assessment report will be July 1 of the "Lancet Oncology" published.
Conclusion How to generate?
Condensed decades of research assessment
Although the first time, WHO Zuochu use of mobile phones may cause cancer of the conclusions, but the research on this issue is not the first time.
A year ago, IARC (IARC) completed a cost of $ 25,000,000, which took decades of research. Period, the global scientists in 13 countries, 2708 patients with gliomas (a type of brain cancer) and the 2409 act of meningitis patients were interviewed earlier, and set the control group, the study concluded that "the total run, do not see cell phone use and increased risk of both the relationship between disease, "but that:" due to the limitations of bias and error, we can not draw firm conclusions analysis. "
To this end, IARC decided to organize expert group on mobile phones and cancer risk assessment of all areas of scientific research.
Thus, the group of hundreds of reports on the human cancer, cancer and other laboratory animals were reviewed by relevant scientific research, assessment, and ultimately concluded that: exposure to mobile phones and other wireless devices, electromagnetic radiation, may cause long-term health effects, particularly is likely to increase cancer risk. Because so many people using mobile phones, and the number is growing, especially among young people and children, so this may become a public health problem.
While the scientists emphasized that mobile phone induced glioma, acoustic neuroma evidence also more "limited", there is not enough evidence to come to the phone cause of other types of cancer does, but overall, cell phone use is "likely to cause cancer risk ".
The scientists did not cause the phone to the quantitative cancer risk, but they mentioned that, according to a study earlier in the day over the past decade an average of half an hour of people use mobile phones, glioma risk appears to be 40 %.
Conclusions are credible?
However, limited evidence may be carcinogenic
IARC is the authority of the cancer research organization, but the introduction of this assessment report has been opposition from some organizations. Federation of International Wireless, said in a statement Ironically, this WHO agencies "do a myriad of assessments, pickles and coffee in the past have made back to a similar conclusion yet."
In the IARC classification, pickles and coffee are "probably carcinogenic", it is indeed controversial. There is evidence that coffee may be related to colorectal cancer, but the other hand, studies have shown that coffee can reduce prostate cancer. The research focuses on the pickles in Korea and Japan, opponents argue that this study only data based on observation, not a scientific control group comparison.
International Wireless Federation also said that the current classification "does not mean that mobile phones cause cancer", "even if there is bias and other data errors, the data of the current evidence is still limited."
The industry body also said, IARC has not made any new study, only the last full assessment of published studies. The agency also proposed that the Federal Communications Commission and the U.S. Food and Drug Administration have to stand, saying there is not enough scientific evidence that mobile phones and cancer and other health problems associated.
In response to these objections, it was defended for the IARC, "debate will continue," the University of Washington bioengineering experts Hengli Lai said in an interview, "However, this is the first related to the World Health Organization statement tell the people should be careful of such radiation. group of experts from around the world, some of which are very respected researchers. If someone says, this group of expert is not good enough, then I do not know who should listen. "
Arguments come from?
Rabbit DNA damage cell phone radiation
80 years from the date of the last century, the global mobile phone users has soared to 50 million, while the relationship between mobile phone use and cancer research is also the medical field in recent years become the focus of controversy.
Electromagnetic radiation can be divided into ionizing radiation (high frequency) and non-ionizing radiation (low frequency), with the former with a cancer risk, such as X-ray, etc., but no definite evidence that the latter would cause cancer, cell phones to launch This low frequency is non-ionizing radiation.
Many scientists believe that the energy wave of mobile phone radiation is too weak, will not damage chemical bonds or cause DNA damage, cancer, and repeatedly emphasized that the non-ionizing radiation can cause cancer of the chemical mechanism has Rengshi Mi.
Animal experiments have shown that the mobile phone radiation can cause DNA damage rabbits and their offspring, but the same as last year's report IRAC, there is no epidemiological study to a mobile phone radiation and cancer risk will be directly linked.
However, the U.S. health sector, a study this year showed that less than 1 hour a day mobile phone use will lead to increased brain activity, but scientists do not know exactly what this means. The report also pointed out that even trace amounts of mobile phone radiation frequency signals can also cause significant changes in the brain, study participants scientists believe that even low levels of non-ionizing radiation, does not undermine the bond, but may also lead to injury.
Scientific arguments, so that mobile phone users are confused. Face a potential health threat, although the IARC's evaluation report did not give the proposal to use mobile phones, but the participants in the meeting that the use of ear plugs and other hands-free device, or change to text messaging, can reduce cell phone radiation.

Cell phone radiation level
WHO's statement came out, it immediately aroused the concern of mobile phone industry. May 31, an American charity organization "United States Environmental Working Group," immediately launched a report on the number of brands of mobile phone radiation level ranking.
The lowest ranking of special radiation absorption rate (SAR)
1.Beyond E-Tech Duet D8 0.109
2. Samsung Eternity SGH-A867 0.194
3. Samsung "Blue Earth" 0.196
4. Samsung SGH-G800 0.23
5. Samsung Soul 0.24
Special radiation absorption rate of the highest ranking
1. Motorola V195s 1.6
2. Motorola Zine ZN5 1.59
3. Motorola Rival 1.59
4. Kyocera Jax S1300 1.55
5. Motorola VU204 1.55
"Specific absorption rate": the number of radio measuring the actual radiation energy absorbed by the body. Mobile phone radiation peak, the European regulations for the 2.0SAR, the United States 1.6SAR, there has not been mandatory standards.
