Radiation Protection Clothing Is Really Protective Against The Fetus.

　　 Radiation-proof clothes It is almost the "standard" of pregnant women's equipment. In fact, as long as we talk with these hard parents, we can know whether they have any need to wear the radiation protection clothing and drums in their hearts. A prospective father said that he should put his wife in the safe and ask for peace for the baby. It is precisely this kind of "peace seeking" mentality coupled with the vague concept of science that the radiation protection clothing market has been booming. Not only has it been updated, but its products are constantly upgrading. Metals from the beginning fibre The silk is turned into a metal coating, and the material is also modified from copper to "silver ions". But does radiation protection really have a protective effect on the health of the fetus, or is it just seeking a safe pit product?

　　 "Silver ion" radiation protection clothing is best seller.

There are more than 20 kinds of radiation protection clothes on the hangers in a women's and infant products store near Tuanjiehu. Press Fabric Material is divided into three types: metal fiber (excluding silver), metal coating and silver ion series. The price ranges from 200 to 1000 yuan, and the materials and styles used determine the price of the product. Among them, the most expensive and better selling product is the silver ion radiation protection clothing, which is very light and the price is more than 1000 yuan.

At the scene, the reporters showed the magic effect of these radiation protective clothing to the reporters, and wrapped the mobile phone with protective clothing, and the signal of the cell phone was immediately shielded. Businesses say that radiation protection clothing can be used for one year as long as it doesn't rub.

Beijing clothing Wang Baihua, associate professor of College of materials science and engineering, said there is no national or industry standard specifically formulated for radiation protection clothing for pregnant women. Many pregnant women's radiation protection clothing is sandwiched with wire, mainly for general electromagnetic waves to play a protective role. However, because of no clear standards, there is no relevant regulations on the protective effectiveness of these radiation protective clothing. China issued a recommended standard for microwave shielding and protective clothing only in December 2009, and did not target the mandatory national standards for the entire radiation protection products. Therefore, there is no relevant departments to measure and supervise them, and even it is difficult to investigate and punish enterprises suspected of false propaganda.

　　 Cause can not completely shield electromagnetic wave radiation.

Ma Tanyuan, director of the Department of nuclear medicine, First Affiliated Hospital of Tsinghua University, said that the principle of radiation protection clothing for pregnant women is similar to the Faraday cage we know well, shielding electromagnetic waves through metal screens. Radiation has broad sense and narrow sense. Radiation in narrow sense is what we call nuclear radiation. Generalized radiation refers to electromagnetic radiation, which is caused by computers and mobile phones. But the range of electromagnetic radiation is very wide. From mobile phone signal to microwave oven, even solar heat and light is a kind of electromagnetic radiation. The effects of these electromagnetic radiation on human body are caused by electromagnetic resonance of human cell molecules or tissues. The frequency of electromagnetic radiation will have many effects on the human body, and at present, electromagnetic radiation which is harmful to the human body is relatively rare in daily life. Therefore, it is not necessary to wear radiation protection clothing for electromagnetic radiation.

Ma Tanyuan said that the electromagnetic radiation in life has a wide spectrum, and the radiation protection clothing may be able to prevent the radiation from a certain band, but it is impossible to prevent all the radiation from the spectrum. The radiation protection clothing can shield the cell phone signal because the cell phone is wrapped in the radiation protection clothing completely, and people can not be completely wrapped by the radiation protection material in the radiation protection clothing, so even wearing the radiation proof clothing can not guarantee that the electromagnetic radiation is completely shielded.

　　 Harmful radiation cannot be shielded.

There are many kinds of radiation. Since the generalized electromagnetic radiation has little effect on pregnant women, is it possible that other radiations can cause harm to pregnant women?

Ma Tanyuan said that at present, medical research shows that pregnant women exposed to ionizing radiation such as X rays and gamma rays during pregnancy are harmful. However, there must be a certain amount of lead in the protective clothing for ionizing radiation, so this dress will be very bulky, like the protective clothing for rubber in the radiology department of the hospital. Now the pregnant women's radiation protection clothing on the market is very light, and it should not contain lead, so it can not play a role in ionizing radiation. As for mobile phones and computers often used by people, most of them are electromagnetic waves. "Only a single particle's energy is higher than that of the molecular bond energy, which can cause DNA damage and even induce fetal malformation or cancer. Most other visible light, infrared, microwave and radio waves can not induce fetal malformation or cancer. There is no scientific evidence to support the spread of leukemia caused by high-voltage lines and fetal malformations caused by cell phone radiation.

　 Remind B-ultrasonic radiation not to do more.

According to Ma Ling, deputy director of Beijing maternal and child health care center, pregnant women should pay attention to B-ultrasound radiation. If there is no special case, pregnant women should do two B ultrasound during 18 to 24 weeks of pregnancy and 36 weeks later.

Some parents think that radiation suits are useless even if they are useless. Ma Ling said that radiation protection clothing will make some beneficial things to be shielded. Some radiation from nature is beneficial to human body, such as infrared rays in sunlight. Proper exposure to sunlight is beneficial to both the fetus and herself, especially in the north, where sunlight is used for a short time, so do not always wear radiation proof clothing. "Radiation protection clothing is sought after by many people. A large part of the reason is derived from the taboos of pregnant women, such as the fact that pregnant women can not touch cold objects. This taboo mentality has greatly restricted the activities of pregnant women, and to some extent, it is also harmful to the development of the fetus. Therefore, we should not only change people's misunderstandings in science, but also reverse the lack of ideas. In western countries, few pregnant women wear radiation proof clothing, and there are no taboos. "
