吸收中子屏蔽板聚乙烯抗辐射含硼板

Radiation - resistant boron - containing polyethylene plate polyethylene radiation - resistant boron plate, mainly boron plays a role in absorption. Boron has a relatively large reaction section for low-energy neutrons. Before hydrogen reaction, low-energy neutrons are almost completely absorbed by boron. Boron-containing polyethylene can achieve the required shielding effect of boron-containing polyethylene when the percentage of mass is 10% and the thickness is 15cm. On this basis, if the boron content or thickness is increased, the integral leakage of neutrons 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屏蔽效果已达到要求。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.
