The MCNP-5 code was utilized to simulate the mass attenuation coefficient (MAC) of a novel series of chalcogenide spinels called XCrTe (where X represents Co, Fe, and Cu). Following preparation through the conventional solid-state reaction method, the samples exhibited densities ranging from 6.42 to 7.04 g cm. By comparing the obtained results with the XCOM data, we observed a significant correlation with a relative difference of 0–1.93%. The accuracy of the simulated data was further confirmed by performing the Kolmogorov-Smirnov test. Based on the calculated MAC, we derived several radiation parameters. Finally, these derived results were compared to previously published data for evaluation. These parameters showed the superiority of the sample containing Co (CT-Co) over other samples on gamma and neutron shielding properties. The results illustrate the ability of studied samples to absorb most gamma-ray photons within low energies, which suggests the potential for applying radiation shielding fields.

评估无铅 XCr2Te4 硫族尖晶石合金的电离辐射衰减效率：使用 MCNP 代码的研究

MCNP-5 代码用于模拟称为 XCrTe（其中 X 代表 Co、Fe 和 Cu）的新型硫族尖晶石系列的质量衰减系数 (MAC)。通过传统固相反应方法制备后，样品的密度范围为6.42至7.04 g cm。通过将获得的结果与 XCOM 数据进行比较，我们观察到显着相关性，相对差异为 0-1.93%。通过进行柯尔莫哥洛夫-斯米尔诺夫检验进一步证实了模拟数据的准确性。根据计算出的 MAC，我们得出了几个辐射参数。最后，将这些得出的结果与之前发布的数据进行比较以进行评估。这些参数表明，含钴样品（CT-Co）在伽马和中子屏蔽性能方面优于其他样品。结果说明了所研究的样品在低能量下吸收大多数伽马射线光子的能力，这表明应用辐射屏蔽场的潜力。
