For neutron shielding applications in nuclear power projects and nuclear equipment fabrication, modular boron-containing shielding blocks are recognized as practical base materials by nuclear power chief engineers and nuclear equipment manufacturers. Boasting outstanding neutron leakage prevention performance, they stand as the mainstream material for all types of nuclear radiation shielding projects. Unlike conventional monolithic cast shielding structures, these modular shielding blocks feature factory prefabricated split components. They thoroughly resolve long-standing industry pain points including complicated on-site construction and radiation leakage through assembly joints.

Manufactured with polyethylene as the base material and integrated boron carbide, the boron-containing shielding blocks deliver reliable shielding via a dual-layer protection mechanism. Hydrogen atoms in the substrate efficiently slow down high-energy fast neutrons, while boron elements accurately absorb thermal neutrons. This fundamentally blocks the escape of neutron radiation, delivering consistent shielding performance without secondary radioactive contamination.

Thanks to their practical structure, stable performance and wide adaptability, boron-containing shielding blocks are extensively deployed in major nuclear power projects. They also serve as standard shielding substrates for nuclear equipment production, neutron research laboratories and BNCT medical treatment rooms, ranking as highly recognized supporting neutron shielding materials across the industry.
