Experts refute *** "Pregnant radiation suits are useless"

Recently, the famous domestic fight fighter *** directed the radiation protection service for pregnant women: “This is China’s unique business **! Electromagnetic radiation generated by daily appliances will not affect human health, even if it affects, the so-called radiation protection service. Also does not achieve the shielding effect, must wear the specialized radiation protection suit that wraps the entire body to be able to do."*** This statement has caused an uproar, many pregnant mothers and pregnant mothers are very confused, that pregnant women radiation suits in the end is Buy it or not? Wear it or not? In the end there is no use? The author recently learned from relevant authorities that pregnant women's radiation protection suits are certainly useful. The difference lies in how much radiation can be attenuated. Related national measurement standards are being actively formulated and will be introduced as soon as the end of next year.

Maternal mothers puzzled: Experts are self-contradictory. Whoever listened to the radiation protection service for pregnant women who have become “standard” for pregnant mothers has recently become an object of defamation. The opinions on the Internet are divided into two groups. Saying that "pregnant women do not need to wear radiation suits, do not need to be nervous", the other school said that "regardless of their use, they would rather be credible, not credible". The two factions hold their own words, so that pregnant women are falling like clouds: in the end to hear who?

Just pregnant with pregnant ** told the author, recently went shopping, found that pregnant women radiation protection clothes are expensive, are in several hundred dollars, although we can not determine whether the radiation suit is beneficial to the fetus, but she still pay to buy Under the. "There is so much pollution now. Computers, mobile phones, iPads, TVs, microwave ovens... There are a lot of sources of radiation around you. If your baby is affected, it will be a lifetime."

Sun Jinliang, academician of the Chinese Academy of Engineering, said in his book that on May 7, 1999, the State Environmental Protection Administration reported that China's electromagnetic radiation pollution environment does exist. In fact, this kind of "pollution" is a new problem that arises in the process of human society's progress toward safe production, civilized production, and high-grade life. It exists objectively, and it does not have to be overtly frustrated and frightened, but it cannot be taken lightly. Therefore, it is thought that Chen Yu** thinks that wearing protective clothing against radiation is better than protecting pregnant moms who are not protected.

The author then telephone interviewed Professor Lu Yinghua of Beijing University of Posts and Telecommunications. He told the author that the body's absorption of electromagnetic waves will produce thermal effects, which is generally recognized. As for whether non-thermal and non-thermal effects will have an impact on human health? At present, the international community has yet to form a unified conclusion, and it is now in a suspicious state. For some sensitive populations such as pregnant women, they should take as little contact with electromagnetic sources as possible, and they can also take some shielding measures such as wearing radiation suits to reduce the intensity of electromagnetic radiation, which is beneficial to them.

The author's inquiry was informed that China only introduced a "Microwave Screen Protective Clothing" recommended standard in December 2009, and there is no mandatory national standard for the entire radiation protection product. At present, the standards for radiation protection products on the market are set by the manufacturers themselves, and the standards set by each company are different.

Due to the lack of relevant metrics, there is no relevant department to measure and supervise it, and there is no corresponding agency to sample and test the shielding effectiveness of the radiation protection products sold on the market. This makes the outside world have a voice to question the current radiation protection suits. .

The expert spoke: The usefulness is certain, but the problem of how much is attenuated has been detected. The radiation protection suit on the market can block most of the electromagnetic radiation.

According to Gu Hongyu, a member of the National Garment Standardization Technical Committee, at present, the national standard for the detection of radiation suits is still under formulation, and relevant departments have not yet quantified relevant data and indicators. However, some people on the Internet say that radiation protection suits are not useful, and they must come up with their own evidence.

In Gu Hongxuan's opinion, radiation protection clothing has a certain role, but in the end how much effect can be achieved, how much radiation can be prevented, 100% radiation protection is absolutely impossible, like UV protection, this protection is relative Of course, counterfeit pregnant women radiation suits are certainly not protective.

As one of the experts involved in the formulation of the national standard, Gu Hongxuan said that relevant departments are formulating professional parameters and will be published as soon as possible. “The standard for radiation protection clothing is being drafted. Now it is the stage of technological research. After a draft is prepared, it needs to be demonstrated and discussed by all parties, and after the agreement is reached, it is still necessary for national approval to be officially released. Therefore, I am also unsure of the standard. The specific time of release."

She also said, "Now that the radiation protection service can not block the controversy of radiation, I think there is no quantitative standard for radiation protection clothing in the country. After standards are formulated, there will be relevant data to support and there will be a unified. In order to determine how much effect there is."

“Radiation suits must be shielded from radiation in the 300MHz to 3GHz microwave band,” said Professor Jin Xipeng of the School of Public Health at Fudan University.

The author also interviewed Lu Fumin, chief engineer of the Shanghai Institute of Metrology and Measurement Technology, and he said: “Pregnant women have a certain role in radiation protection services, but at present the national standard for the detection of electromagnetic radiation suits is still in development.” According to Lu Fumin, they had previously We have conducted anti-electromagnetic radiation tests on pregnant women's anti-radiation suits of many brands on the market, including straps, vests and other styles. We have found that radiation protection suits on the market can block most of the electromagnetic radiation.” “Of course, 100% protection is required. Radiation is difficult, and even if the attenuation reaches 99%, 1% cannot be blocked. During the trial, we found that pregnant women's radiation protection clothes are mainly to protect the mother's heart and belly parts (ie, the baby's location), and the effect on the edge is weak, and the protective effect is closely related to the fabric and style of the clothing. ”

Expert: The excessive influence of electromagnetic radiation during pregnancy is bound to affect the development of the fetus. A pregnant cat mother is lazily lying on a 9-inch black-and-white TV set. After she gave birth to a baby, the owner discovered that of the 4 kittens, 3 was only disabled. Some were blind and some were blind. The owner of the cat was a professor at Shanxi Medical College. He gave this as a subject to a young lecturer. This lecturer is Liu Wenkui. Liu Wenkui began his exploration of the disability of cats. He has been obsessed with for more than 40 years and has become a famous expert in the field of electromagnetic radiation in China.

As the first person to propose physical pollution in China, Professor Liu Wenkui of the School of Public Health of Shanxi Medical University has made a fundamental contribution to the prevention and control of electromagnetic radiation pollution in China. He said that in the human body, the crystals and reproductive system of the eyeball are most sensitive to electromagnetic radiation contamination. If women are over-affected by electromagnetic radiation during pregnancy, they will inevitably affect the development of the fetus, resulting in congenital malformations and birth defects that are congenitally silly. Therefore, he suggested that women must try to avoid contact and less exposure to electromagnetic radiation two months before pregnancy. For more and more popular mobile phones, Liu Wenkui suggested that children aged 12 or under should not use it because adults can use mobile phones to call for 10 minutes. Within 15 minutes, the adverse effects of electromagnetic radiation can be eliminated, while children It takes 30-50 minutes.

Liu Wenkui appealed that China should legislate to prevent and control electromagnetic radiation pollution as soon as possible. At present, it is necessary to formulate a comprehensive electromagnetic radiation standard as soon as possible and make clear provisions on the intensity of various electromagnetic radiation.

Wang Shulan, a professor and doctoral supervisor at Fudan University’s School of Public Health, also wrote that electromagnetic radiation may cause fetal chromosome damage and teratogenesis. At present, people's living environment has more and more electromagnetic radiation, more and more complex, more and more power, and higher frequency. Therefore, new 21st century medical concepts should be adopted for prevention and prevention, and artificial electromagnetic energy should be used in a civilized manner, such as the development of electromagnetic radiation shielding materials to deal with electromagnetic radiation pollution.

Related Links: History and Current Status of Electromagnetic Radiation Protective Clothing Electromagnetic radiation shielding service has been in existence for more than 40 years and has gone through three stages. Before the 1970s, it was the first stage from scratch. Products were limited to military, scientific research, medical and health, and factories and mines; in the 1970s and 1980s, products began to enter ordinary families, developed rapidly, and increased in variety. The second phase of the increase in the number; from the 1990s to the present, for the third phase, the electromagnetic radiation shielding service developed rapidly, the quality was optimized, the number increased rapidly, and New Products continued to emerge.

Since the 1980s, electronic and electrical appliances have swarmed into all fields and millions of households in China. People's electromagnetic environment has changed, and people are in urgent need of personal protection. In May 1999, our civilian electromagnetic shielding suit appeared in Shanghai. According to incomplete statistics, since less than a decade after the first batch of civil electromagnetic radiation shielding clothing appeared, the number of units that have been developed, produced, and marketed abroad has been thousands, and there are also hundreds in China. It has now become a high-tech and new-type industrial complex that involves electronics industry, textile industry, biomedicine, military research, and inspection and supervision.

Will electromagnetic radiation shielding clothes be abandoned in the future? The consultant of the National Electromagnetic Shielding Materials Standardization Technical Committee and the senior engineer of the Shanghai Textile Science Research Institute clearly stated that “no”. And gave some explanations: Although are currently working to reduce the radiation leakage of electronic appliances, but electromagnetic radiation shielding service is still essential. Because there is some radiation that does not conform to electromagnetic compatibility standards, nor can it be shielded, nor can it be time-limited, but it cannot be far away from sensitive people in sensitive electromagnetic environments, sensitive parts of the human body, and people who have low endurance to magnetic fields. , Can wear electromagnetic radiation shielding clothing for personal protection.
