It is carcinogenic to treat mobile phone radiation reason

Assistant Researcher of scientific research institute of the labour protection of Beijing Li ZhaoJiang
Recently, the international cancer research center under World Health Organization claims, using mobile phone or other wireless communication equipment " may increase the probability that the mankind suffers from cancer " . Use the wireless communication equipment to bring out cerebroma? We listen to the expert explaining - -
What influence does the electromagnetic radiation of the mobile phone on earth have on health? This is a topic that people pay close attention to. The common mobile phone works in 800 MHZ (mhz) Get 1800 MHZ (mhz) Frequency range. This frequency band is the radio frequency (rf) Little wave band. Like microwave oven, mobile phone and the electric magnetic field happening in radiation, to the medium around while launching Thaksin's symbol to exchange, including the human muscular tissue produced the thermal effect.
World is not that the ionization radiation protects the committee (icnirp) Adopt it than the absorption rate (sar) To weigh the intensity of thermal effect of mobile phone radiation. Than the definition of the absorption rate is: During 6 minutes continuously, the average of electromagnetic radiation energy that the muscular tissue of each kilogram absorbs. It is 2 watts kilogram that world does not the ionization radiation protect the security limit that the committee proposes. There are special instrument and apparatus more than the measurement of the absorption rate. Mobile phone website and manual of manufacturer should it indicates product their to be more worthier than absorption rate.
Animal's experiment Inspire tumour and cataract
Because when the mobile phone uses often close to the head, most heat produced on people's head surface, cause some temperature to rise. The blood circulation of the heads of people will disperse some heat, but people's eyes cornea does not have the regulating function of this temperature. It proves, as the rabbit receives are up to 2- 3 hours for radiation of 100- 140 watts kilogram than the absorption rate value that experimental, eyes will present cataract. Some animal experiments find, the microwave radiation of the low intensity can promote the growth of tumour. When the mouse is exposed to than the electric magnetic field of microwave that the absorption rate is 1 watt kilogram, dna structure that mouse's brain organizes will be destroyed. Whether these experimental results are suitable for mankind's remaining to study yet. But in any case, can't exclude from having these possibility to endanger to the mankind.
Human research Long term administration may increase the risk
Because fast popularization and people of the mobile phone increase to the worry that the health influence of mobile phone radiation day by day, so a lot of countries have launched scientific research in this field.
In 2006, one in Denmark was as long as 20 years, the study on 420000 people's follow-up investigation indicated, the mobile phone was used and had nothing to do with cancer. However, Germany's radiation protects the federal office to think the conclusion of Denmark is inaccurate. Someone is based on mobile phone subscribers but not users to criticizes the Danish result of study, because a lot of people buy the mobile phone to use for family.
In 2007, Swedish orebro university Dr. lennart hardell draws the conclusion after studying a large amount of relevant scientific research literature carefully, use the mobile phone for an hour every day, the probability of the brain tumour of future trouble will increase obviously in 10.
The research of Britain, Germany and Northern European countries think, though has not found the risk that obvious tumour increases among the cellphone subscribers investigated, but use the mobile phone for a long time ' More than 10 years) The influence that may cause is worth further studying.
Australia radiation protect, advise with the nuclear security service, because children uses the shortage of Mobile and brain tumour relation data, parents should limit children's use for mobile phone. Though there is not evidence yet, someone thinks it has already had growth of tumour that the electromagnetic radiation of the mobile phone will be accelerated.
There are 13 research projects of mobile phone radiation and tumour relation which countries participate in after the international cancer research institution of World Health Organization has launched one, the result of study is issued since 2004. Some results of study reveal, long-term (more than 10 years) In the user, the emergence of acoustic nerve tumour and glioma may have relation with the use of the mobile phone. In using the users for nearly 10 years, the relation that have not found brain tumour generally and the mobile phone uses. But use the mobile phone and may increase the probability that glioma happen in a large amount.
Before putting through You had better keep away from the mobile phone the head
Standard of restricting mobile phone radiation level that our country has not used coming more than the absorption rate yet. The intensity of electromagnetic radiation of the mobile phone can be estimated with common electromagnetic radiation standard, namely measure the electric field of mobile phone radiation or intensity of magnetic field, then compare with relevant standards with. Stipulate to the mobile phone working frequency band electric field intensity limit for 12 volts rice in China's national standard gb8702-1988. The radiation intensity when a lot of mobile phones are dialing is higher than this value.
Mobile phone the intersection of radiation and standard should come, use for reference, safe demarcating valueing absolutely or not. Studies have suggested, even within the safety standards of the countries concerned, microwave radiation will cause the destruction to dna. Because everybody's physiological state is different, the radiation of the same dosage may not be influenced some people at all, but may cause pathological change to other people. So, even use the mobile phone which accords with the safety standard of radiation, can't guarantee to have no one that influences to everybody's health either.
The strongest value of electromagnetic radiation of the mobile phone usually appears during dialing. So, before putting through, had better keep away from the mobile phone the head. Electromagnetic radiation decays with the distance, it is the farther from the radiant, the smaller radiation intensity is.
While using the mobile phone, can reduce the time of each conversation; Look for signals in the strong place to dial; And reduce mobile phone radiation to healthy influence by means such as the message,etc. with the wired earphone or mobile phone loudspeaker.
