In this study, brass (Cu/Zn) reinforced polymer composites with different proportions of brass powders were fabricated. Different types of nuclear shielding parameters such as mass and linear attenuation coefficients, radiation protection efficiency, half and tenth value layers, and effective atomic number values were determined experimentally and theoretically in the energy range of 0.060-1.408 MeV in terms of gamma-ray shielding capabilities of fabricated polymer composites. A high Purity Germanium detector (HPGe) in conjunction with a Multi-Channel Analyzer (MCA) and twenty-two characteristic gamma-ray energies have been used in the experimental phase. In addition, the exposure and energy absorption buildup factors of reinforced Cu/Zn composites were calculated, and relative dose distribution values were computed to verify them. Proton mass stopping power (Ψ), proton projected range (Φ), alpha mass stopping power (Ψ), and alpha projected range (Φ) parameters, which indicate the interactions of the produced composites with charged particle radiation, were investigated. Fast neutron removal cross-section (Σ) results were determined to give an idea in terms of neutron shielding. According to the obtained results, it is reported that the CuZn20 coded sample's ability to attenuate gamma-ray and charged particle radiation is more efficient than that of other prepared composites. A CuZn05 coded sample was found to be more suitable for neutron shielding capability.
在本研究中，制备了具有不同比例黄铜粉末的黄铜（铜/锌）增强聚合物复合材料。根据制备的聚合物复合材料的伽马射线屏蔽能力，在0.060 - 1.408 MeV的能量范围内，通过实验和理论确定了不同类型的核屏蔽参数，如质量和线性衰减系数、辐射防护效率、半值层和十分之一值层以及有效原子序数。在实验阶段，使用了一台高纯锗探测器（HPGe）与多道分析仪（MCA）以及22种特征伽马射线能量。此外，计算了增强铜/锌复合材料的照射量和能量吸收积累因子，并计算了相对剂量分布值以进行验证。研究了表明所制备的复合材料与带电粒子辐射相互作用的质子质量阻止本领（Ψ）、质子射程（Φ）、α粒子质量阻止本领（Ψ）和α粒子射程（Φ）参数。确定了快中子去除截面（Σ）结果，以便在中子屏蔽方面提供参考。根据获得的结果，据报道，编号为CuZn20的样品对伽马射线和带电粒子辐射的衰减能力比其他制备的复合材料更有效。发现编号为CuZn05的样品在中子屏蔽能力方面更合适。
