生物屏蔽含硼板中的聚乙烯是碳?xì)浠衔铮瑲淞扛?，對快中子有良好的減弱能力，硼吸收熱中子、鉛對γ輻射的屏蔽特別有效，因此，生物屏蔽含硼板具有屏蔽快中子，熱中子和γ輻射的綜合屏蔽效果，含硼聚乙烯板的推廣應(yīng)用有助于屏蔽結(jié)構(gòu)的簡化，能夠減輕屏蔽體的重量，縮小屏蔽體的體積。而且保留了聚乙烯板耐磨、抗沖擊、自潤滑、摩擦系數(shù)小、抗腐蝕和耐老化等優(yōu)質(zhì)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.
