Why do boron-containing boards have so many advantages? Please let me analyze them. Polyethylene is a hydrocarbon compound with high hydrogen content, which has a good ability to weaken fast neutrons. Boron absorbs thermal neutrons and lead shields Y radiation. It is particularly effective. Therefore, the lead-boron polyethylene sheet has a comprehensive shielding effect of shielding fast neutrons, thermal neutrons and gamma radiation. The popularization and application of lead-boron polyethylene sheets can help simplify the shielding structure and reduce the weight of the shield. Reducing the size of the shield is mainly used to shield neutrons and radiation. In recent years, China has devoted itself to the development of the nuclear industry. The nuclear industry has high radiation intensity, so it is necessary to use boron-containing plates to cause radiation damage.
Advantages of boron-containing board: polyethylene is a hydrocarbon with high hydrogen content, which has a good ability to weaken fast neutrons. Boron absorbs thermal neutrons and absorbs gamma radiation particularly well. Therefore, boron-containing polyethylene board has shielding Fast neutrons have the effect of absorbing thermal neutrons, and the popularization and application of boron-containing polyethylene sheets can help simplify the shielding structure, reduce the weight and volume of the shielding body.
The boron-containing board has good engineering performance, good dimensional stability, and the fast neutron performance is obviously better than that of polyethylene. The boron-containing polyethylene board has a stable production process and good processing performance, which is completely suitable for engineering applications.
Over the years, our company has developed a large number of practical equipment for radiation protection research and engineering applications in my country. The industry has been widely used and achieved good results.
