Detailed investigations on the photon and neutron attenuation properties of various BiBr₃ and PbSO₄ incorporated polyester composites have been carried out in terms of evaluating their potential use as new radiation shielding materials. Utilizing HPGe detector-based γ-ray spectrometry, the mass attenuation coefficient values of the polyester materials were calculated over a wide photon energy range of 59.5–1408 keV. The experimental results have been compared to those obtained using XCOM software and showed that the measured attenuation coefficient was in good agreement with the theoretical results at all photon energies studied. Moreover, BiBr₃(20%) and PbSO₄(20%) exhibit the minimum half value layers (5.94 and 6.58 cm at 661 keV) and highest radiation protection efficiencies (69.80 and 69.67% at 59.9 keV), while the neutron removal cross-sections of BiBr₃(5%) and PbSO₄(5%) samples were higher than the other composites studied.

就各种掺入BiBr ₃和PbSO _4的聚酯复合材料的光子和中子衰减特性进行了详细的研究，以评估它们作为新型辐射屏蔽材料的潜在用途。利用基于HPGe检测器的γ射线光谱，可以在59.5–1408 keV的宽光子能量范围内计算聚酯材料的质量衰减系数值。将实验结果与使用XCOM软件获得的结果进行了比较，结果表明，在所有研究的光子能量下，测得的衰减系数与理论结果均吻合良好。此外，BiBr ₃（20％）和PbSO ₄（20％）表现出最小的半值层（661 keV时为5.94和6.58 cm）和最高辐射防护效率（59.9 keV时为69.80和69.67％），而BiBr ₃（5％）和PbSO的中子去除截面_4个（5％）样品高于其他研究的复合材料。
