Boron-containing polyethylene is an efficient anti-neutron radiation material with good catalytic activity, low corrosion to equipment, and no environmental pollution.
Polyethylene is a hydrocarbon with high hydrogen content, and has a good ability to weaken fast neutrons. Boron thermal neutrons and lead are particularly effective in shielding gamma radiation. Therefore, borated polyethylene plates can shield fast neutrons and heat. The comprehensive shielding effect of neutron and gamma radiation, and the popularization and application of boron-containing polyethylene plates help simplify the shielding structure, reduce the weight of the shield, and reduce the volume of the shield.
Boron-containing polyethylene is an efficient anti-neutron radiation material with good catalytic activity, low corrosion to equipment, and no environmental pollution. Compared with traditional metal and concrete, boron-containing polyethylene composite material has the characteristics of low density, good attenuation curve, convenient use, low cost, and good processing performance. The boron-containing polyethylene has good radiation resistance and can be effectively used in medium The neutron radiation in the mixed radiation field of γ and γ can meet the needs of radiation occasions with different energy levels. It is used as a fuel depot for nuclear power plants and product tanks for nuclear experiments, neutron beam collimators, neutron traps, medical and health care and other aspects as radiation shielding and absorption materials.
