In fields with strict radiation protection requirements such as nuclear industry, medical treatment and scientific research, material selection is directly related to personnel safety and equipment stability. As a new type of composite protective material, boron-containing polyethylene board has gradually become the preferred alternative to traditional protective materials by virtue of its unique performance advantages.

Its core working principle lies in the synergistic effect of boron elements and polyethylene matrix. Hydrogen atoms in polyethylene can rapidly slow down high-energy fast neutrons, while boron-10 isotopes can efficiently capture slowed-down thermal neutrons and convert them into harmless particles through nuclear reactions without generating intense secondary gamma rays. It achieves efficient neutron shielding and also takes into account gamma ray attenuation performance.

Compared with traditional protective materials such as lead plates and concrete, boron-containing polyethylene boards feature prominent lightweight advantages. Its density is only 1/8 of lead and 1/2 of concrete. It can be carried and installed without heavy equipment, greatly reducing construction difficulty and load-bearing pressure. Meanwhile, it boasts excellent mechanical properties and durability, featuring wear resistance, impact resistance, acid and alkali resistance and anti-aging performance. It is non-toxic, eco-friendly and free of activation products, conforming to the development trend of green protection industry.

At present, boron-containing polyethylene boards are widely applied in reactor protection of nuclear power plants, neutron scattering laboratories and other scenarios. Boron content, specifications and dimensions can be customized according to different radiation intensities to meet various complex protection demands. With the continuous upgrading of nuclear technology and medical equipment, boron-containing polyethylene boards play an increasingly important role in the field of radiation protection relying on the core characteristics of high efficiency, light weight and safety, providing solid support for safety protection in various industries.
