铅硼聚乙烯等材料的DT中子透射性能研究

Measurements of DT Neutron Transmittance of Pb-B Polythene

利用液体闪烁探测器BC501A,测量得到铅硼聚乙烯等8组实验样品的DT中子透射率实验数据。结果表明,在8组样品中,有较高钨含量样品的DT中子屏蔽性能较好,样品之间的中子透射率最大的相对差异为17%。实验数据可供中子辐射屏蔽设计参考。

The DT neutron transmittance of 8 kinds of Pb-B polythene were measured by BC501A detector. The results showed that DT neutron shielding performannce of sample with higher W content is better than others in the 8 samples. The transmittance maximum relative difference between the 8 samples is 17%. The data may be useful to the radiation shielding design of neutron.
