Lead glass is a frequently used radiation protection product. Its main features are: very good light transmission. Because radiation protection lead glass is made of glass, its light transmission is relatively good. It is installed in the radiation department of the hospital as a window. It is a good way to use it, or install it as an observation window in some industrial laboratories. Because some equipment in the ward and the experimental materials in the industrial laboratory may have some radioactive substances more or less, which can not only have good sex, but also play a very good protective role. The anti-radiation performance is very good because the main component of anti-radiation lead glass has a very strong lead content in addition to glass. The density of this lead element is very large enough to block the intrusion of all harmful substances. As a potassium silicate glass, lead glass has been impregnated with lead oxide (12%-28% by weight) during manufacture.
