Experts heated debate: can not wear radiation suits?
Recently, "wearing a radiation suit is far more likely to harm" remarks gave rise to much controversy. December 22, as is currently the only anti-electromagnetic radiation radiation Association Shanghai Association for the first time to respond to the matter, and that it is responsible to tell the consumer, anti-electromagnetic radiation clothes are valid for electromagnetic shielding, anti-electromagnetic radiation clothes are not may become collectors of electromagnetic waves. Because consumers can not have or are wearing anti-electromagnetic radiation clothes have any fears and concerns.
Electromagnetic radiation experts reject the "wearing radiation suits useless, harmful"
Electromagnetic shielding materials, the National Standardization Technical Committee, Shanghai electromagnetic radiation Association spokesman Huang Jianhua said: radiation protection services in the end there is no use, every year caused a lot of controversy, and even now "bad theory" came out, our association has to come out clarify the facts, we hope to use science to speak.
Shanghai Association of anti-electromagnetic radiation in the December 22 public statement issued to the media mentioned that Chen Feng lab for the anti-electromagnetic radiation clothes to do a test, and thus concluded that the electromagnetic radiation on human clothing not only fails to The protective effect of electromagnetic radiation but will become collector, increasing the damage of radiation on the human body, such a non-standard experimental conclusions are not scientific.
"Statement", said Chen Feng laboratory demonstration experiments in non-professional occasions by non-professionals, non-professional approach with the result, if the electromagnetic radiation which would come to serve "no effect" on or wearing anti- Electromagnetic radiation dose of "bad" theory, is extremely reckless and irresponsible, in misleading the media and consumers. The individual who issued the so-called anti-electromagnetic radiation clothes is a commercial fraud is an extremely irresponsible remarks behavior.
Huang Jianhua said that the "anti-electromagnetic radiation clothes incident" has the anti-electromagnetic radiation caused great impact on industry, the majority also had a misleading consumers, we have the responsibility, the duty to play our role, to the media and consumer who make a statement, to avoid further deterioration of this event.
In addition, rumors on the network, "radiation monitoring service that no one," one said the association also made a response.
Huang Jianhua said: "The service is not without radiation monitoring, radiation protection in recent years, the relevant state departments have done a lot of textile work standardization, but also made great progress has been worked out on yarn, fabric, test methods , clothing and many other career related with radiation protection standards, and there are several standards in the preparation of these standards have become our industry in the product design, development, production in the main specification.
Chen Feng lab changed in the blog
In last week's media experiment by Chen Feng, reasoning out of the "harmful radiation suit, said," caused an uproar after the recent bursts of Bowen Chen Feng laboratory to clarify related issues.
Chen Feng said: "The news specially emphasized, is only a special experimental setup, the electromagnetic shielding clothes into the case after the reflection is absolutely not to say that the energy of the signal increases, he said," no rigorous experimental program. " "There is no standard test conclusions."
For the "radiation suit radiation suits may be worse than not wearing it? This is a test result?" Chen Feng, A. "Although this rarely occurs, but possible, the film played the two extremes test describe this situation. "
For the "wear worse than not wearing it? Experimental results it is," Chen Feng replied: "Although this rarely occurs, but possible, the film is played two tests described in this extreme situation."
Chen Feng has attracted users answer cursed. Friends said a pregnant wife to wear radiation suits to buy, read Chen Feng's program, the results have been Xinhuang Huang, no definite conclusion is possible, or, generally, mostly, rarely, as far as possible, these words of just did not say the same.
"Radiation suit event" also attracted the attention of the legal profession.
Dong Gang Rongde law firm counsel, (TV) correspondent commissioned testing behavior does not have the legal effect of course, the test results are valid worthy of further research, and the test data because it did not have the breadth, it is not In the case of rights as valid evidence.
Through reports, we see that only one inspector for the corresponding radiation detection service, but service on the market a wide range of radiation, of varying quality, protective functions are not the same, only one testing organization radiation detection service is derived from test results are not representative and universal.
Inspection department utterance: Useful yes, but how much attenuation problem
Shanghai Institute of Measurement and Testing is the testing organization in radiation protection fabric authoritative institutions. Electromagnetic shielding materials as the country's General Technical Committee for Standardization, Measurement and Testing Technology, Shanghai Institute of Engineer Lu Fumin, said: "Pregnant women have the role of radiation protection services in the affirmative."
According to Lu Fumin said, after they have many brands on the market for anti-radiation protection services for pregnant women electromagnetic radiation experiments, including harness, vest style, etc., found on the market most of the radiation suit to block electromagnetic radiation "." Of course, to be 100% of the radiation is very difficult, even if attenuation up to 99% and 1% can not stop. Doing the test, we found that pregnant women, radiation suits to protect pregnant mother is the heart of the main parts of the belly area (ie, the location of the baby), the effect will be weaker by the edge of the area, and that the protective effect of the number and apparel fabrics, styles are closely related. "
But why testing authority "useful for radiation protection services," but the market has continued to voice their doubts it?
It is reported that China's only in December 2009 issued a "microwave shielding protective clothing," the recommended standards, not mandatory for the entire national standards for radiation protection products. The radiation products currently on the market are manufacturers set their own standards, and standards developed for each business is different.
National Standardization Technical Committee Gu Hongfeng clothing said that at present, the detection of radiation protection services in the national standard is still developing, yet there is no relevant data and indicators relevant to quantify, but some people say online service does not use radiation, but also come up with their own basis to.
In Gu Hongfeng view, there is the role of radiation protection services is yes, but in the end how much effect can play, how much radiation can prevent the problem, 100% of the radiation that is absolutely impossible, as the same UV protection, this protection is relatively , of course, fake clothes is definitely not pregnant radiation protection features.
As experts in the development of national standard radiation, Gu Hongfeng said that relevant departments are developing professional parameters, will come out as soon as possible. "Radiation protection service standards are being drafted, and now the research stage of technology, etc. come up with a draft, but also requires the parties to demonstrate, discuss, and other comments need to reach agreement after approval by the State to the official release, so I'm not sure the standard release a specific time. "
She said, "Now for the radiation protection service can not block the radiation of the controversy, I think it is at present no quantitative national radiation protection service for the standard, after the introduction of such standards, there will be data to support, there will be a unified argument, in order to determine how much effect in the end. "
"Radiation protection service for the 300MHz-3GHz microwave radiation in this band certainly has a shielding effect," Fudan University School of Public Health Professor Jin Xipeng said.
During pregnancy by the excessive influence of electromagnetic radiation, is bound to affect fetal development
According to statistics, an average per household electrical appliances in China is 26, the state of radiation for each appliance standards, but many appliances in one room will have much yet to detect accumulation of radiation, electromagnetic pollution with household appliances The increase is entering people's lives.
As the first person to make physical pollution, Shanxi Medical University, School of Public Health, Professor Liu Wenkui electromagnetic radiation in China who have made a groundbreaking pollution prevention contributions.
A pregnant mother cat, lying lazily on a 9 inch black and white TV. Waiting for her baby after birth, the owner discovered four kittens, and yet only 3 disabled, some lame, some blind. Cat owners was a professor at Shanxi Medical College. He put this as a subject, to a young lecturer. The lecturer is Liu Wenkui. Liu Wenkui from disabled began to explore the cat, 40 years crush, become well-known experts in the field of electromagnetic radiation. He engaged in long-term biological effects of electromagnetic fields and environmental protection research.
He said that in the human body, the eye's lens and the reproductive system is most sensitive to electromagnetic radiation pollution. If women during pregnancy by the excessive influence of electromagnetic radiation, is bound to affect fetal development, resulting in congenital malformations and congenital birth defects in the shape of stupidity. Therefore, he suggested that women in the first two months of pregnancy, we must try not to touch, and less exposure to electromagnetic radiation. For the growing popularity of mobile phones, Liu Wenkui recommendation 12 years of age or children under the age of 16, it is best not to use, because adult mobile phone to play 10 minutes, 15 minutes can make to eliminate the adverse effects of electromagnetic radiation, while the children are need 30-50 minutes. Beijing University of Posts and Professor Lv Yinghua, said after the body to absorb electromagnetic waves produce thermal effects, which is recognized by all. As to whether it will produce non-thermal effects and non-thermal effects are harmful to human health effects? Current international unified conclusion has not yet formed, and now in a suspicious state. For some sensitive populations such as pregnant women groups, it should take to minimize exposure to electromagnetic sources where you can also take some radiation shielding measures such as wearing clothes to weaken the intensity of electromagnetic radiation, which would be useful for them is
