Radiation - resistant boron - containing polyethylene plate polyethylene radiation - containing boron plate, mainly boron absorption. The reaction section of boron to low-energy neutrons is relatively large. Before hydrogen reaction, the low-energy neutrons have been completely absorbed by boron. When the mass percentage of boron containing polyethylene is 10 ‰ and the thickness is 15cm, the protective effect of boron containing polyethylene to neutrons has reached the requirements. If the boron content or thickness is added on this basis, the neutron integral leakage amount will not change.
抗辐射含硼聚乙烯板 聚乙烯抗辐射含硼板中，主要是硼起吸收作用。硼对低能中子的反应截面比较大，在还没有发生氢的反应之前低能中子基本已被硼完全吸收，含硼聚乙烯在质量百分比为10﹪、厚度为15cm时，含硼聚乙烯对中子的防护效果已达到要求。在此基础上再增加含硼量或者厚度，中子的积分泄露量基本不发生变化.
