Abstract This study investigated the radiation shielding capacity of undoped polymer composite and lead (II) chloride (PbCl2)-containing polymer composite samples. The PbCl2 and polyester resin were used as filler and base materials, respectively. The PbCl2 was added to the polyester resin from 5 wt% to 20 wt%, and so an undoped polymer composite and four polymer composite samples each with different PbCl2/polymer resin ratios were investigated for their radiation attenuation capacity. Experimental data of the samples were taken using an HPGe detector, and 241Am, 133Ba, 57Co, 22Na, 137Cs, 152Eu, 54Mn and 60Co radioactive point sources were used with energies in the range of 59.5–1408.0 keV. The experimental data were compared with both those simulated with FLUKA code and those theoretically calculated in WinXCOM. Mass attenuation coefficients used in estimating the shielding capacity of the samples were in good agreement with those found using FLUKA and WinXCOM. Radiation protection efficiency was improved by 244% especially at 59.5 keV energy by using PbCl2(20%) polymer composite compared to undoped polymer composite. The sample with the maximum weight percentage of PbCl2, PbCl2(20%), had the highest attenuation coefficients and lowest absorption thicknesses, and had the best radiation shielding property compared to the other polymer composite samples.

氯化铅（II）对聚合物复合材料核屏蔽能力的影响

摘要 本研究调查了未掺杂的聚合物复合材料和含氯化铅 (PbCl2) 的聚合物复合材料样品的辐射屏蔽能力。PbCl2 和聚酯树脂分别用作填料和基材。将 PbCl2 从 5% 到 20%（重量）添加到聚酯树脂中，因此研究了一种未掺杂的聚合物复合材料和四种聚合物复合材料样品，每个样品具有不同的 PbCl2/聚合物树脂比率，以研究它们的辐射衰减能力。样品的实验数据是使用 HPGe 探测器获取的，并且使用能量在 59.5-1408.0 keV 范围内的 241Am、133Ba、57Co、22Na、137Cs、152Eu、54Mn 和 60Co 放射点源。将实验数据与用 FLUKA 代码模拟的数据和在 WinXCOM 中理论计算的数据进行了比较。用于估计样品屏蔽能力的质量衰减系数与使用 FLUKA 和 WinXCOM 发现的那些非常一致。与未掺杂的聚合物复合材料相比，使用 PbCl2(20%) 聚合物复合材料的辐射防护效率提高了 244%，尤其是在 59.5 keV 能量下。与其他聚合物复合样品相比，PbCl2重量百分比最大的样品PbCl2(20%)具有最高的衰减系数和最低的吸收厚度，并且具有最好的辐射屏蔽性能。
