In order to prevent radiation damage, users need to type the selected radiation protection project light protection. Only in this way can the shielding function be played. Because penetration and different types of radiation hazards are different, it is also the key basis for radiation proof lead doors. In order to select the appropriate radiation proof lead door, everyone needs the radiation type environment and penetration energy, and rigorous scientific analysis is required. The radiation protection lead gate protects the radiation source, the author between buildings, and the shielding and restriction of rays, reducing the damage of rays. In sufficient light, we still need to wear special protective equipment. As we all know, the medical industry and radiation research institutions are the main institutions - radiation and radiation protection lead door users. In order to ensure our health, radiation workers must strictly abide by the rules and wear lead radiation protection equipment. Radiation protection is to prevent radiation spillage. For everyone, the radiation damage caused by tools should be screened. It is important to pay attention to the health and well-being of everyone who is used for radiation protection. Compared with other metals, lead has good shielding because of its high density. But other metals can also be used.
