Can pregnant women really protect against radiation?

Can your maternity dress protect against radiation? This is a popular greeting between mothers and mothers nowadays. However, the anti-radiation maternity wear on the market has a wide range of functions and prices, and it is confusing.

"Radiation threat" spreads pregnant women to save money for "relief"

Ms. Li, who lives in Shuangta Temple Street in Taiyuan, is an editor of a newspaper in Taiyuan City. She needs to sit in front of a computer for eight hours a day for work. Recently, she had a baby. Under the proposal of "Come on," Ms. Li bought a radiation protection suit for pregnant women in hopes of reducing the effects of computer radiation on her baby.

Like Ms. Li, many women of child-bearing age and mothers-to-be are also affected by the "radiation threat" spread through various channels, and invariably aim at anti-radiation maternity dress. In some hospitals next to the baby pregnancy store, shopping malls in the baby pregnancy counters, business sites on the baby pregnant virtual store, radiation protection maternity dress has become a hot trend.

Recently, the Shanxi Daily News has also received phone calls. The readers have doubts about this type of anti-radiation maternity dress that is not much different from ordinary clothing. The reporter asked on the Internet forums that there were different opinions on this issue, and the most was actually “Buying home is more than a map.”

Protective clothing price high material are "high-tech"

The reporter visited a number of baby products stores in Taiyuan City in the past few days and found that these shops are equipped with anti-radiation maternity dress counters.

In an infant pregnancy store next to the Maternal and Child Health Hospital in Shanxi Province, the reporter said that she wants to purchase anti-radiation maternity clothes. A female clerk pointed at a row of clothes bearing the word "radiation proof": "This is a dress style, with silver ion radiation protection material, lightweight and stylish, the best radiation protection; that kind of nano-isolation Layer, the price is slightly lower..."

The reporter learned from the interview that the anti-radiation maternity dresses currently on the market are divided into three types according to the radiation protection material used and the protection methods: metal plating (or nano-radiation protection layer) series, metal wires (or nanometers) Radiation protection materials) blended series, the latest silver ion fiber series. The price of anti-radiation maternity clothes is not cheap, the price of all-maturing maternity clothes is concentrated at 400-700 yuan, and the fashionable silver-ion fiber full-protected maternity dress price is as high as 1,000 yuan, semi-protective maternity clothes such as vests, aprons, Abdominal and so on, the price is more than 200 yuan to 400 yuan. When the merchants sell, they all interpret the anti-radiation maternity dress as “high-tech products” and “well-known brands in the industry”. In order to explain its good radiation protection effect, some so-called branded maternity dresses are also testing and certification by certain organizations, claiming that the blocking rate for various kinds of radiation is as high as 99.9%.

In addition to radiation protection effects, radiation protection maternity dress is also advertised with other advantages. In an infant pregnancy store near the Taiyuan Maternal and Child Health Hospital, the clerk strongly recommended a radiation-proof maternity dress to reporters, claiming that the fabrics have common pathogens such as Escherichia coli, Staphylococcus aureus, and Candida albicans. Excellent inhibitory effect. The clerk explained that “in the fetal forming period, once it is exposed to electromagnetic radiation, it may affect intellectual development, resulting in serious congenital disease!” The reporter was surprised, and he hoped that the other party would introduce the principle of radiation to the fetus in more detail. The female shopkeeper slyly replied: "What kind of particles are specific rays, I'm not sure, but you also know that electronic products have radiation, and our clothes can be protected against radiation!"

Promotional Demonstration Multi-professionals

In order to verify the effectiveness of anti-radiation maternity dress, most consumers have adopted a “local approach”: enclose the mobile phone in a radiation-proof maternity dress and wait another half-minute to make a call, and then judge whether it should be based on the presence or absence of a telephone signal or signal strength. Clothing's ability to block radiation. This "method" has been recommended by businesses and has now become one of the most popular test methods in the market.

There are also more intuitive test methods provided by merchants: Connect a spherical glass lamp, which is supposed to be a microwave radiometer, to the power supply. The glass lamp starts to flash. Businessmen keep the radiation-proof maternity dress between the ball and the electroscope. The electroscope is not Responsive, and then she put on another piece of regular clothing, and the pilot light turned on. Businesses explained that this is the effect of radiation shielding materials to isolate rays.

“$$$$$$”

However, professionals say that neither of these test methods is sufficient to prove that its efficacy is advertised so well. Masking out mobile phone signals does not completely block or absorb radiation. The mobile phone's frequency range is between 380 MHz and 2700 MHz. It belongs to medium-frequency long wave. However, in real life, the wavelength and frequency of electromagnetic waves are different. Using mobile phone detection can only show that radiation protection can prevent some radiation in certain wavelength ranges. It is not easy to determine the effectiveness of radiation protection clothing. For the test of the spherical radiometer, the electric pen is not bright, it does not mean that there is no radiation, because when the telephone is called and the television is watched, the surrounding electric pen will not be bright.

There is no standard in the country that cares for yourself

How much radiation protection maternity dress can prevent radiation? People in the industrial and commercial department stated that currently only anti-radiation maternity dresses sold in the market are subject to corporate standards, and the country has not introduced relevant standards, and its protective performance cannot be measured and supervised. Provincial Consumers Association staff told reporters that among the complaints that have been accepted, the salesmen of radiation-proof maternity dress products that have been surveyed have admitted that publicity has exaggerated words.

Dr. Suo Yuping, deputy chief physician of the Department of Obstetrics of People's Hospital of Shanxi Province, said: “There is no clinical data to prove how harmful the radiation of the ordinary living environment and work environment is to the fetus, and it is impossible to know how much harm the radiation protection maternity dress can reduce. The radiation protection maternity dress claims 99.9% protection rate has no practical value and can only mislead pregnant women."

For some businesses, they claim that their sales of radiation protection maternity clothing is the use of loops made of metal fibers in the garment to generate induced currents, and that the induced electric current produces a counter-electromagnetic field for shielding. This reporter called the Taiyuan Quality and Technical Supervision Bureau. In the light chemical department, the staff told the reporter: “The shielding effect of metal is its natural property. According to the weaving method of clothing fabrics, generally no ring current will be generated. If the current generates a reverse magnetic field, the generated electromagnetic waves cannot be identified either. It is harmless to the human body.” In the end, how much radiation is harmful to the human body, and there is no scientific experiment in the world; radiation protection suits can block certain electromagnetic radiation, but it cannot define its effect.

Mom considerate baby science protection is more important

For people who are in the high pressure field for a long time, especially mothers who give birth to babies, how do they do protective work in daily life?

Suo Yuping said that at present, there are no standards related to radiation protection for pregnant women, and it is very difficult for the standards to be formulated. At present, there is no scientific proof of how the electromagnetic wave actually harms the human body. Although animal experiments show that electromagnetic waves are harmful to the nervous system, brain tissue, and immune system of animals, they cannot simply be said to harm the human body in the same way.

She said that mothers who choose to buy anti-radiation maternity clothes must pay attention to their “practicality”. They must not only be able to prevent radiation, but also have the basic attributes of clothing – warmth, elasticity and washability. When mothers and mothers protect, they must keep a certain distance from the electron radiation source, and they cannot be exposed to radiation sources for a long time. In particular, for pregnant women who work on video screens, they generally advocate leaving the radiation source after 20 minutes of video screen operations. Play protective effect. After the screen operation, including washing the face after watching TV, to reduce radioactive dust contamination.

Suo Yuping reminded her that radiation protection maternity wear cannot stop X-rays. Therefore, for pregnant women, medical X-ray or CT examination is not advocated. If the doctor thinks it must be checked, pregnant women must use medical lead protective clothing to protect them from their non-irradiated parts, especially the abdomen.
