Lead plate is the primary component of lead, lead is a more important heavy metal, has a lot of characteristics, the more important is that its density is relatively large, hardness and various anti-corrosion and anti-wear functions are relatively high. With a relatively large mass and density, mainly used in the production of lead batteries, acid industry and metallurgical industry with lead plate, lead pipe as fabric maintenance equipment, electrical industry as lead cable sheath and fuse. Lead alloys containing tin and antimony are used for printing type, lead tin alloys are used for making fusible lead electrodes, and lead plates and lead plated steel plates are used in the construction industry. Lead has good absorption of X-ray and gamma rays and is widely used as maintenance data for X-ray machines and atomic energy equipment. Lead has been or will be replaced by other information in some fields for reasons of toxicity and economics. One of the most important is used in the field of radiation prevention. Here’s how the lead plate plays a role in preventing radiation:
α particle penetration is weak, a piece of paper can block; Protective lead plate can completely block, protective alpha radiation focus do not eat, stained skin. Another is the beta ray, which has moderate penetration. The general protective lead plate can block most rays, but the beta ray is usually protected with a barrier of lower atomic number, so as not to produce bremsstrahlung. Finally, gamma ray is produced with α and β, with strong penetration, a certain thickness of the protective lead plate can block a certain proportion of the intensity of gamma ray, radioactive intensity with the thickness of the protective lead plate according to the exponential law attenuation, theoretically can not be completely blocked. But there’s no need for a complete barrier. In fact, radioactivity is everywhere, and there’s radiation in the surrounding space, as long as it’s kept within reasonable limits.
