2. Radiation protection clothing uses the loop composed of metal fibers in clothing to generate induced current, which generates reverse electromagnetic field for shielding. A good metal conductor can reflect electromagnetic waves, that is, when the aperture of the metal mesh is smaller than the wavelength of electromagnetic waves (wavelength = light speed/frequency) 1/4, electromagnetic waves cannot penetrate the metal mesh.
3. All radiation protection suits for pregnant women in the market are made according to this principle, and the fabrics contain conductive metal fibers or conductive silver fibers, wherein the metal fibers refer to stainless steel metal fibers, and the silver fibers refer to composite fibers formed by nano-silver ions infiltrating into nylon fibers. These two kinds of fibers have good conductivity, so they can play a role in shielding electromagnetic waves.

Precautions for radiation protection clothing
1, effect: Regular radiation protection clothing brands have been tested by authoritative testing institutions. Radiation protection effect can refer to the test report. It is not recommended to look at dB values because there are many definitions of this concept.
It is difficult for non-professionals to judge.
2. Color: At present, the most common color of radiation protection clothing on the market is navy blue. Because the fabric of radiation protection clothing contains metal wires, it is not suitable for frequent washing, so choose a stain-resistant color. The navy's radiation suit is more resistant to dirt.
3. Fabric type: There are many kinds of radiation-proof fabrics on the market. There are coating type, multi-ion type, metal fiber type and so on. There are many differences in radiation protection effect, wearing comfort, air permeability and washing resistance.
