The presented study focused on investigating the radiation shielding properties of polyester/pyrite/niobium diboride (FeSNbB) composites. Various gamma-ray shielding parameters were evaluated with help of a HPGe detector system. Theoretical and simulation results are further evaluated by WinXCOM, GEANT4 and FLUKA codes, and the obtained results are compared with experimental values in the energy region 59.5 keV–1332.5 keV. The prepared samples are additionally evaluated using kerma relative to air values and Exposure build-up factors. Then, for the evaluation of neutron radiation shielding, effective removal cross sections for fast neutrons were determined for FeSNbB composites. Electron attenuation efficiency (AE%) for the produced composites was assessed across the energy spectrum of 4 MeV–18 MeV, utilizing experimental data from a Linac machine and theoretical predictions from Eclipse TPS. The results were found to be compatible with each other. FeSNbB50 has the best shielding properties among the studied composites.

用于辐射防护的含黄铁矿和二硼化铌的聚酯复合材料的生产和评估


本研究的重点是研究聚酯/黄铁矿/二硼化铌 （FeSNbB） 复合材料的辐射屏蔽性能。在 HPGe 探测器系统的帮助下评估了各种伽马射线屏蔽参数。通过WinXCOM、GEANT4和FLUKA代码对理论和仿真结果进行了进一步评估，并将所得结果与59.5 keV–1332.5 keV能量区的实验值进行了比较。此外，使用相对于空气值和暴露积累因子的 kerma 对制备的样品进行评估。然后，为了评价中子辐射屏蔽，确定了 FeSNbB 复合材料的快中子有效去除截面。利用直线加速器机器的实验数据和 Eclipse TPS 的理论预测，在 4 MeV–18 MeV 的能谱范围内评估了所生产复合材料的电子衰减效率 （AE%）。结果发现彼此兼容。FeSNbB50 在所研究的复合材料中具有最好的屏蔽性能。
