Radiation protection clothing has a certain shelf life, because radiation protection clothing is made by using the principle that good metal conductors can reflect electromagnetic waves. The key to shielding electromagnetic radiation of radiation protection clothing lies in metal fibers or silver ions embedded in clothing fabrics. However, with long-term exposure to air, washing and wear, these metal substances will inevitably be oxidized and damaged, which will gradually reduce or even disappear the shielding effect of radiation protection clothing. Therefore, radiation protection clothing has a shelf life.

However, although the radiation protection suit has a shelf life, it is also a very long process from strong to weak. How long will the radiation suit expire? If there is no intentional damage or force majeure, the shielding effect will not be lost for a month or two. Generally speaking, the shelf life of radiation protection suits is more than 12 months, so it is no problem to complete the protection task during pregnancy. Of course, some experienced brands have adopted some special technologies when making fabrics of radiation protection suits, which further improve the oxidation resistance and washing resistance of radiation protection suits and extend the shelf life of radiation protection suits. Among these technologies, the excellent silver ion precision quenching electroplating technology is more representative.
