生物屏蔽含硼板中的聚乙烯是碳氢化合物，含氢量高，对快中子有良好的减弱能力，硼吸收热中子、铅对γ辐射的屏蔽特别有效，因此，生物屏蔽含硼板具有屏蔽快中子，热中子和γ辐射的综合屏蔽效果，含硼聚乙烯板的推广应用有助于屏蔽结构的简化，能够减轻屏蔽体的重量，缩小屏蔽体的体积。而且保留了聚乙烯板耐磨、抗冲击、自润滑、摩擦系数小、抗腐蚀和耐老化等优质的特性。

Polyethylene in biological shielding boron containing plate is a hydrocarbon with high hydrogen content, which has good weakening ability to fast neutrons γ The radiation shielding is particularly effective. Therefore, the biological shielding boron plate has the advantages of shielding fast neutrons, thermal neutrons and thermal neutrons γ The comprehensive shielding effect of radiation and the popularization and application of boron containing polyethylene sheet are helpful to simplify the shielding structure, reduce the weight and volume of shielding body. Moreover, it retains the high-quality characteristics of polyethylene sheet, such as wear resistance, impact resistance, self-lubricating, low friction coefficient, corrosion resistance and aging resistance.
