The rapid development and application of ultra-high molecular weight polyethylene (UHMWPE) plate containing boron in nuclear power, radio logical diagnosis and treatment, industry, high-energy physics research and other fields has become an important radiation damage hazard factor. In terms of fast neutron shielding principle, high density polyethylene has a good moderating effect on fast neutron, and boron element (10B) has a high thermal neutron absorption cross section. Therefore, boron polyethylene with a certain content of 10B becomes a good shielding material for fast neutron shielding.In order to improve the neutron shielding effect and reduce the cost of boron-containing polyethylene shielding materials, a boron-containing ultra high molecular weight polyethylene (UHMWPE) plate was developed according to the characteristics of polyethylene with large diffuse fast neutron and boron thermal neutron absorption cross section.
Containing 10% boron polyethylene plate has good engineering properties, dimension stability is good, has the satisfactory gamma radiation resistance, using temperature is 80 ~ 100 ℃, shielding thermal and fast neutron and gamma radiation is obviously better than the performance of polyethylene, studies have shown that boron anti-radiation polyethylene plate can effectively prevent the radiation and neutron radiation to individuals and the society the harm caused.Boron carbide, borax, boron trioxide and lead powder can be added according to customers' requirements, and the content is 5%-50%
