One-step molding of boron polyethylene cylindrical neutron shield
The anti-neutron radiation of boron polyethylene cylinder has good engineering performance, good dimensional stability, and satisfactory resistance to gamma radiation. Obviously better than polyethylene, research shows that boron-containing radiation-proof polyethylene board can effectively prevent the harm caused by nuclear radiation and neutron radiation to individuals and society.
