Boron-containing polyethylene (bpe) is a relatively cheap neutron shielding material. As with other neutron shielding materials, the material is used by neutrons to generate corrosion rays. Compared to neutron shielding, safer radiation is a second-order dose. In the polyethylene ball containing boron, it is mainly boron that absorbs. Boron response to low energy neutron cross section is larger, before has not happened hydrogen reaction basic boron has been completely absorbed, low energy neutron boron polyethylene in the quality percentage of 10 ﹪, thickness is 15 cm, boron polyethylene protective effect of neutron has reached the requirement. On this basis, the amount or thickness of boron is increased, and the integral leakage of neutrons is basically unchanged.

含硼聚乙烯是一種相對廉價的中子防護材料，對其中子防護特性已進行過一維基準 實驗。與其他中子防護材料一樣，該材料在中子的作用下產生γ射線。相對于防護中子而言，γ射線是二級劑量。  而在含硼聚乙烯球中，主要是硼起吸收作用。硼對低能中子的反應截面比較大，在還沒有發生氫的反應之前低能中子基本已被硼完全吸收，含硼聚乙烯在質量百分比為10﹪、厚度為15cm時，含硼聚乙烯對中子的防護效果已達到要求。在此基礎上再增加含硼量或者厚度，中子的積分泄露量基本不發生變化。
