宁津县鸿宝化工有限公司新研制成功含硼聚乙烯板材，具有防中子辐射、防*等*产品，并获得*专利，研究表明含硼防辐射聚乙烯板能够有效的*****及中子辐射给个人及社会造成的危害

    含硼聚乙烯是一种相对廉价的中子屏蔽材料，对其中子屏蔽特性已进行过一维基准 实验。与其他中子屏蔽材料一样，该材料在中子的作用下产生γ射线。相对于屏蔽中子而言，γ射线是二级剂量。  而在含硼聚乙烯球中，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*量基本不发生变化。  宁津鸿宝化工有限公司通过对本实验的****终结论在对含硼聚乙烯的百分比与厚度上再次做了一系列的研发，具有*辐照性能好，无活化产物，次级γ射线能量低；化学稳定性好，耐腐蚀，*、无气味；机械强度高，表面光滑、便于去污、机械加工方便、易于安装维修的特点。

Ningjin Hongbao Chemical Co., Ltd. has recently developed boron containing polyethylene sheet, with high performance products, such as neutron radiation protection and nuclear radiation protection, and has obtained a national patent. The research shows that boron-containing radiation-proof polyethylene plate can effectively prevent the damage caused by nuclear radiation and neutron radiatio*individuals and society. Boron-containing polyethylene is a relatively cheap neutr*hielding material A one-dimensional benchmark experiment has been carried out on the subshielding characteristics. Like other neutr*hielding materials, the material produces γ-rays under the action of neutr*. γ-rays are second-order doses relative to neutr* being shielded. Boron plays an importa*ole in the absorption of boron-containing polyethylene balls. The reaction cross section of boron for low-energy neutr* is relatively large, and the low-energy neutr* h*e been completely absorbed by boron before the reaction of hydrogen has taken place. When the mass percentage of boron-containing polyethylene is 10% and the thickness of boron polyethylene is 15cm, The shielding effect of boron-containing polyethylene to neutron has reached the requirement. On this basis, the integral leakage of neutr* is basically unchanged by increasing boron conte*r thickness. Through the final conclusion of this experiment, Ningjin Hongbao Chemical Co., Ltd. has done a series of research and developme*n the percentage and thickness of boron containing polyethylene again. It has good radiation resistance, no activation products and low secondary γ -ray energy. Good chemical stability, corrosion resistance, No*xic, odorless, high mechanical strength, *ooth surface, easy decontamination, easy machining, easy installation and maintenance.
