How To Judge The Shielding Performance Of Anti Radiation Maternity Clothing

　　 Current market Anti Radiation Maternity Dress There are roughly three types.

The first is the radiation protective maternity clothes with plating. This kind of radiation protective maternity clothes is cheap, hard to handle, poor in ventilation, and cannot be washed. The biggest disadvantage is that the metal plated on the surface is easy to fall off and become powder. If the pregnant woman inhales it into her stomach, it will affect the health of the fetus.

The second one is the finished radiation proof maternity clothing made of metal wire, which is known to all. This radiation proof maternity clothing product has good hand feel, good breathability, can be washed, and the radiation proof effect is general. The disadvantage is that the metal wire is easy to climb and break, and easy to penetrate into the skin.

The third is the radiation protection made by "silver plating and cementation technology of antibacterial and radiation resistant fiber" clothing It is the representative of the latest generation of radiation protective clothing in the world at present. Its shielding value is more than 60dB, which can completely shield mobile phone signals and other radiation without side effects. At the same time, it has the functions of killing bacteria, breathable and washable. The disadvantage is high cost and easy to change color.

Businessmen remind that the best prevention for pregnant women is to stay away from radiation sources. If it cannot be completely avoided, then more comparisons must be made when selecting radiation protection products.

　 Expert: a means of self-protection

　　 How to judge radiation protection Shielding performance of maternity clothes Good or bad is a common concern of businesses and consumers.

An industry personage said that the radiation proof maternity clothes woven from coarse metal fibers with high chromium content could not completely shield the mobile phone signal. This radiation proof maternity clothes had certain effects on computers, televisions and other electrical appliances with radiation. The level of shielding value is mainly determined by the level of dB value. If the dB value is above 20, it can only block ordinary electromagnetic waves, but it cannot block the mobile phone signal; Only maternity clothes with a dB value above 50 can shield mobile phone signals.

Li Guodong, senior engineer of Shanghai Test Center under the Shanghai Institute of Measurement and Testing Technology, clearly hinted that "the commonly said radiation proof cloth is just like this cloth A very fine wire mesh fiber is added. The quality of this mesh metal fiber is also good or bad. For poor quality products, the content of this metal fiber is only a few percent. The product has soft hand feel, low cost and poor protection effect; Good quality products, mesh metal fiber content of 18% - 20%, this kind of products feel hardened, high cost, high manufacturing difficulty, but the protective effect is good. "

However, some experts believe that radiation protection Maternity clothing The promotion and application of the anti radiation clothing has a history of decades in China. Due to technical reasons, the early anti radiation clothing is relatively thick, with low production efficiency and high cost. It is mainly used by staff engaged in radar, microwave communication and other departments. With the progress of technology, many manufacturers can weave this kind of clothing into light, thin, soft, breathable, hygroscopic, washable, and electromagnetic shielding effect is greatly improved. Therefore, as far as the current technical level is concerned, it is a convenient and effective means of self-protection for pregnant women to wear radiation protective clothing.
