Experts Refute Fang Fang'S "Useless Theory Of Radiation Protection Clothing For Pregnant Women"

Recently, Fang Fang, a famous anti fake fighter in China, directed against pregnant women.

Pregnant mothers are puzzled: experts say they are self contradictory.

Pregnant women's "standard" pregnant women's radiation protection clothing has recently become the object of the killing of Fang Zi Zi. The opinions on the Internet are divided into two groups. One is that "pregnant women do not need to wear radiation proof clothing and do not have to be nervous."

The two schools are different from each other. Let pregnant mothers fall into the clouds: who are they listening to?

Miss Chen, who is pregnant with her pregnancy, told the author that recently she went shopping and found that the price of radiation protection clothing for pregnant women was very expensive. They were hundreds of dollars. Although it was not clear whether the radiation protection clothing was beneficial to the fetus, she still paid for it.

"Now there's so much pollution, computers, cell phones, IPAD, TV, microwave ovens...

There is a lot of radiation around us. If babies are affected, it will be a lifetime. "

Sun Jinliang, a member of the Chinese Academy of engineering, said in a book that in May 7, 1999, the State Environmental Protection Administration reported that China's electromagnetic radiation pollution environment did exist.

In fact, this "pollution" is a new problem in the process of human society moving towards safe production, civilized production and high quality life. It is an objective problem. It does not need to be fussy and frightened, but it should not be taken lightly.

So Miss Chen believes that wearing protective clothing against radiation is better than no pregnant mother.

I then interviewed Professor Lv Yinghua of Beijing University of Posts and Telecommunications.

He told the author that after the body absorbs electromagnetic waves, it will produce thermal effects. This is universally acknowledged.

Whether there will be non thermal effects and whether non thermal effects will have an impact on human health? At present, there is no unified conclusion in the world, and now it is in a suspicious state.

For some sensitive groups, such as pregnant women, they should try to minimize exposure to electromagnetic sources, and take some shielding measures, such as wearing radiation proof clothing to reduce electromagnetic radiation intensity, which will be beneficial to them.

My enquiry was informed that in December 2009, China issued a recommended standard for "microwave shielding and protective clothing", and did not target the mandatory national standards for the entire radiation protection products.

At present, the standards of the radiation protection products on the market are all set by the manufacturers themselves, and the standards set by each enterprise are different.

Due to the lack of relevant measurement standards, there is no relevant department to measure and supervise it, and no corresponding agencies have sampled the shielding effectiveness of the radiation protection products sold on the market, which makes the outside world have doubts about the current radiation protection clothing.

Experts say: usefulness is yes, but just how much.

After testing, the radiation proof clothing on the market can cover most of the electromagnetic radiation.

Gu Hongfeng, a member of the national clothing Standardization Technical Committee, said that at present, the national standard for the detection of radiation protection clothing is still being worked out, and the relevant departments have not quantified the relevant data and indicators.

But some people on the Internet say that radiation protection clothing is useless, but also to come up with their own basis.

In Gu Hongfeng's view, the role of radiation protection clothing is positive. It is just how much effect can be achieved and how many radiation problems can be prevented. 100% radiation protection is absolutely impossible. Just like anti ultraviolet radiation, this protection is relative. Of course, fake pregnant women's radiation protection clothing is definitely not protected.

As one of the experts who participated in the formulation of the national standard, Gu Hongfeng said that the relevant departments are formulating professional parameters and will come out as soon as possible.

The standard of radiation protection clothing is being drafted, and now it is the stage of technology research.

After taking out a preliminary draft, it is necessary for all parties to discuss and discuss it. After the agreement has been reached, it needs to be approved by the state before it can be formally issued.

So I am not sure the specific time of the standard release. "

She also said, "now that the radiation protection clothing can not cover the controversy of radiation, I think the country has no quantitative standards for radiation protection clothing. After the formulation of standards, there will be relevant data to support, and there will be a unified statement, in order to determine how effective the effect is."

"Radiation proof clothing will definitely play a role in shielding the microwave 300MHz - 3GHz radiation," said Professor Jin Xipeng of Fudan University School of public health.

The author also interviewed Lu Fumin, chief engineer of Shanghai metrology and Testing Technology Research Institute. He said: "pregnant women's radiation protection clothing is effective, but at present, the national standard for the detection of electromagnetic radiation suits is still being worked out."

According to Lu Fumin, before they have carried out electromagnetic radiation tests on many brands of pregnant women's radiation protection clothing on the market, including the suspenders, vest and other styles, we found that the radiation protection clothing on the market can cover most of the electromagnetic radiation.

"Of course, it is very difficult to achieve 100% radiation protection, even if the attenuation reaches 99%, and 1% can not stop.

During the experiment, we found that the radiation protection clothing for pregnant women mainly protects the heart part of the pregnant mother, the belly part (that is, where the baby is), and the effect on the edge part will be weak. Moreover, the protective effect is closely related to the fabric and style of the garment.

Expert: excessive exposure to electromagnetic radiation during pregnancy is bound to affect the development of the fetus.

A pregnant cat mother lounging on a 9 inch black and white TV set.

When she gave birth to a baby, the owner found that 3 of the 4 kittens were handicapped, some were crippled and some were blind.

The cat's owner was a professor at Shanxi medical college.

He gave this as a topic to a young lecturer.

This lecturer is Liu Wenkui.

Liu Wenkui began to explore the disability of cats, and for more than 40 years, he became 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 Shanxi Medical University School of public health has made a groundbreaking contribution to the prevention and control of electromagnetic radiation pollution in China.

He said that on the human body, the lens and reproductive system of the eyeball are the most sensitive to electromagnetic radiation pollution.

If women are exposed to excessive electromagnetic radiation during pregnancy, they will affect the development of the fetus, resulting in congenital malformations and congenital birth defects.

Therefore, he suggested that women should avoid contact with and less exposure to electromagnetic radiation during the first two months of pregnancy.

For more and more popular mobile phones, Liu Wenkui recommends that children under the age of 12 or under 16 are best not to use it. Because adults use their mobile phones for 10 minutes, and within 15 minutes, the adverse effects of electromagnetic radiation can be eliminated, while children need 30-50 minutes.

Liu Wenkui appealed that China should legislate against electromagnetic radiation pollution as soon as possible. At present, we should formulate a comprehensive electromagnetic radiation standard as soon as possible, and make clear regulations on the intensity of all kinds of electromagnetic radiation.

Wang Yilan, a professor and doctoral tutor at the school of public health, Fudan University, has also written a book that electromagnetic radiation may cause fetal chromosomal damage and abnormal teratoma.

At present, the electromagnetic radiation in people's living environment is more and more, more and more complex, the power is increasing and the frequency is higher and higher.

Therefore, we should adopt the new concept of "prevention first and prevention first" in twenty-first Century, and use artificial electromagnetic energy in a civilized way, such as developing electromagnetic shielding materials to deal with electromagnetic radiation pollution.

Electromagnetic shielding clothing has been in existence for more than 40 years, and has gone through three stages.

Before 1970s, it was the first stage from scratch. The products were limited to the use of military, scientific research, medical and health, factories and mining enterprises. In twentieth Century 70, 80s, it was the second stage that products began to enter ordinary families, developed rapidly, increased varieties and increased numbers. From 1990s to date, in the third stage, electromagnetic shielding clothing developed rapidly, quality optimized, quantity increased sharply, and new products sprung up.

Since 1980s, electronic and electrical appliances have flocked into all fields of our country and thousands of households. The electromagnetic environment of people has changed, and people are in urgent need of individual protection.

In May 1999, China's civil electromagnetic shielding clothing appeared in Shanghai.

According to incomplete statistics, in the less than ten years since the first batch of civil electromagnetic shielding clothing appeared, there are thousands of overseas research, production and marketing units, and there are hundreds of them in China.

It has now become a high-tech and new industrial consortium involving the electronics industry, textile industry, biomedicine, military industry research and inspection and supervision.

Will the electromagnetic shielding clothing be abandoned in the future? The consultant of the National Standardization Committee of electromagnetic shielding materials and the senior engineer of Shanghai Textile Science Research Institute, Shi Si, clearly said "no".

Some explanations are given: Although all efforts are being made to reduce the radiation leakage of electronic devices, electromagnetic shielding clothing is essential.

Because some of the radiation is neither compatible with electromagnetic compatibility standards, nor can it be shielded, nor can it be limited to time, nor can it be far away from the sensitive population in complex electromagnetic environment, sensitive parts of the human body, and some people with low magnetic field bearing capacity can wear electromagnetic shielding clothing for personal protection.
