It has a good application in the field of medical radiation protection, such as lead door, lead room and CT room reinforcement. It is a cheap and durable material. Lead is widely used as a protective material for X-ray machines and atomic energy devices because of its good absorption of X-ray and gamma rays. Lead plate refers to the plate made by rolling metal lead. The specific gravity is 11.345g/cm3
       At present, the common thickness in China is 0.5-500mm, and the common specification is 1000 * 2000mm. The best machine in China can make the maximum width of 2000mm and the maximum length of 30000mm, and most of them are made of 1  electrolytic lead.
