background From the CCTV exposure radiation suit "useless, harmful", led to a stunned, to the collective anti-radiation industry "discuss". In just one week, the "radiation protection service event" peaked. On December 22, 2011, the National Electromagnetic Shielding Materials Standardization Committee and the Shanghai Anti-Electromagnetic Radiation Association took the lead. Nearly 100 anti-radiation brands gathered in Beijing, refuting the “uselessness†and “harmfulness†of radiation protection suits for themselves. Discuss the argument." Recently, the statement that “wearing a radiation suit may harm the bigger one†has caused controversy. On December 22, 2011, as the only anti-radiation association in China, Shanghai Anti-Electromagnetic Radiation Association responded to this matter for the first time, and told consumers responsibly that anti-electromagnetic radiation suits are effective for shielding electromagnetic waves, and anti-electromagnetic radiation suits are not. It may become a collector of electromagnetic waves, and consumers do not have to have any panic and worry because they have worn or are wearing anti-electromagnetic radiation suits. "Using radiation protection clothes is useless, harmful theory" is not scientific Huang Jianhua, a member of the National Electromagnetic Shielding Materials Standardization Technical Committee and a spokesperson for the Shanghai Anti-Electromagnetic Radiation Association, said: "There is no use for radiation protection suits. Every year, it will cause a lot of controversy. Even now, 'harmful theory' has come out. Our association has to come out. To clarify the facts, we want to speak in science." The Shanghai Anti-Electromagnetic Radiation Association mentioned in a public statement to the media that Chen Feng’s laboratory conducted a test on anti-electromagnetic radiation clothing, and concluded that anti-electromagnetic radiation clothing not only can not protect the human body. It will become a collector of electromagnetic radiation, which will increase the harm of radiation to the human body. The conclusion of such a non-standard experiment is not scientific. According to the "Declaration", the test demonstrated by Chen Feng Lab is the result of non-professional use of non-professional methods in non-professional situations. If this is done, the anti-electromagnetic radiation suit is "useless" or wearing anti-electromagnetic Radiation clothing "harmfulness" is extremely rash and irresponsible and is misleading the media and consumers. It is also an extremely irresponsible behavior for individuals to publish so-called anti-electromagnetic radiation suits as a commercial scam. Huang Jianhua said that the "anti-electromagnetic radiation service incident" has caused a great impact on the entire anti-electromagnetic radiation industry, and has also misled the vast number of consumers. We have the responsibility to play our role in media and consumers. Make a statement to avoid further deterioration of this incident. In addition, the association also responded to the rumor on the Internet that “the radiation protection suit is not supervisedâ€. Huang Jianhua said: "The radiation protection suit is not without supervision. In recent years, the relevant state departments have done a lot of work in the standardization of radiation protection textiles, and have made great progress. They have already formulated yarns, fabrics, test methods, There are many related standards such as occupational radiation protection clothing, and several related standards are in the process of preparation. These standards have become the main norms in the design, research and development and production of enterprises in the industry." Chen Feng Lab changed his blog In a recent media interview, after Chen Feng’s experiment, the “anti-radiation suit harmful theory†caused an uproar, Chen Feng’s lab recently clarified relevant issues. Chen Feng said: "What is specifically emphasized in the news is only a special experimental setup, which is the reflection of electromagnetic waves after entering the shielding suit. It is definitely not that the energy of the signal is improved." He also mentioned that "the experiment in the program is not rigorous" , "There is no standard experimental conclusion." For the question that "wearing radiation protection suits may be worse than not wearing them? Is this the conclusion of the experiment?" Chen Feng replied: "Although this situation rarely occurs, it is possible that the film is played according to The situation described by two extreme tests." Chen Feng’s answer attracted netizens. A netizen also said that his wife was pregnant and bought a radiation-proof suit. She watched Chen Feng’s program. The result has been flustered. There is no affirmative conclusion. It is possible, or, in general, mostly, rarely, and as much as possible. Just like not saying it. The "radiation-proof service incident" has also attracted the attention of the legal profession. Dong Gang, a lawyer of Rongde Law Firm, believes that the commissioning of the test by the reporter does not have legal effect. Whether the test result is legal and valid is worth further research, and the test data cannot be defended because it is not extensive. Used as valid evidence in cases. Through reports, we have seen that the testers have only tested one piece of radiation protection suits. However, there are many types of radiation protection suits on the market, the quality is uneven, and the protective functions are not the same. The inspection mechanism is only one piece. The test results obtained by testing the radiation protection suit are not representative and universal. The inspection department speaks: the radiation protection suit is definitely useful Shanghai Metrology and Testing Institute is one of the authoritative institutions in the current anti-radiation fabric testing organization. Lu Fumin, secretary general of the National Electromagnetic Shielding Material Standardization Technical Committee and chief engineer of the Shanghai Institute of Metrology and Testing Technology, said: "The role of maternity radiation protection suits is certain." According to Lu Fumin, they have already conducted anti-electromagnetic radiation tests on various brands of maternity radiation suits on the market, including slings, vests and other styles, and found that the radiation protection suits on the market can block most of the electromagnetic radiation. "Of course, it is very difficult to achieve 100% radiation protection. Even if the attenuation reaches 99%, there is still 1% unstoppable. In the test, we found that the radiation protection suit for pregnant women mainly protects the heart part of the pregnant mother and the belly. The location (ie the location of the baby) will be weaker on the edge, and the amount of protection is closely related to the fabric and style of the garment." However, why does the authority detect "use of radiation protection suits", and the market has been questioning it all the time? It is reported that China only introduced a recommended standard for "Microwave Shielding Protective Clothing" in December 2009, and there is no mandatory national standard for the entire radiation protection product. At present, the standards for anti-radiation products on the market are determined by the manufacturers themselves, and the standards set by each company are different. Due to the lack of relevant metrics, the voice of the outside world about the current radiation suits has been constant. Gu Hongyu, a member of the National Garment Standardization Technical Committee, said that at present, the national standard for the detection of radiation protection suits is still being worked out. The relevant departments have not yet quantified the relevant data and indicators, but some people on the Internet say that the radiation protection suits are useless, but also to come up with their own The basis for coming. In Gu Hongying's view, the role of radiation protection suits is certain, but how much effect it can play, how much radiation can be prevented, 100% radiation protection is absolutely impossible, just like UV protection, this protection is relative Of course, fake pregnant women's radiation suits are definitely not protective. As one of the experts involved in the formulation of the national standard for radiation prevention, Gu Hongyu said that the relevant departments are formulating professional parameters and will be released as soon as possible. "The radiation protection service standard is being drafted, and now it is the technical research stage. After a first draft is submitted, it still needs argumentation and discussion. After the agreement is reached, it needs to be approved by the state before it can be officially released. Therefore, I am not sure about the standard. The specific time of the release." She also said, "Now that the radiation radiation suit can not block the radiation dispute, I think that the current national standards for radiation protection clothing are not quantified. After the standard is formulated, there will be relevant data to support, there will be a unified In order to determine how much the effect is." "The radiation protection suit has a shielding effect on the radiation of the microwave frequency band of 300MHz-3GHz," said Professor Jin Xipeng of the School of Public Health of Fudan University.
