Abstract Analytic and stochastic methods were proposed for the determination of gamma-ray radiation shielding properties of the glassy composites. Radiation shielding properties such as mass attenuation coefficients, effective atomic numbers, effective electron numbers, build-up factors (exposure build-up factors and energy absorption build-up factors) can be determined with these techniques. A versatile quaternary composite was studied with different mass ratios in order to optimize the gamma radiation attenuation. Exposure build-up factors (EBFs), energy absorption build-up factors (EABFs), effective atomic numbers (Zeff) and effective electron densities (Neff) were calculated via BXCOM. Furthermore, MCNP transport code, version of 6.2, was used to simulate the mass attenuation coefficients (μ/ρ) and the half-value layers (HVLs) of the composites. Since they are compatible, simulation and BXCOM results denote that these methods can be used to determine the radiation shielding parameters for the glassy composites for which there are no satisfactory experimental values available. All in all, the optimum mass ratio, having the highest radiation attenuation, was determined as [Na2Si3O7/Bi2O3(65/35)/B2O3(2)/Sb2O3(11)], so that glassy composite might be preferred as a radiation shield in various applications. The quaternary glassy composites investigated in this study, performs better than ordinary concrete, getting close to pure lead as a radiation shield.

BXCOM和MCNP 6.2代码对四元玻璃态复合材料(Na2Si3O7/Bi2O3/B2O3/Sb2O3)伽马射线屏蔽性能的研究

摘要 提出了测定玻璃复合材料伽马射线辐射屏蔽性能的分析法和随机法。可以使用这些技术确定辐射屏蔽特性,例如质量衰减系数、有效原子序数、有效电子数、累积因子(曝光累积因子和能量吸收累积因子)。为了优化伽马辐射衰减,研究了具有不同质量比的多功能四元复合材料。通过 BXCOM 计算曝光累积因子 (EBF)、能量吸收累积因子 (EABF)、有效原子序数 (Zeff) 和有效电子密度 (Neff)。此外,MCNP 传输代码,版本 6.2,用于模拟复合材料的质量衰减系数 (μ/ρ) 和半值层 (HVL)。由于它们是兼容的,模拟和 BXCOM 结果表明这些方法可用于确定玻璃复合材料的辐射屏蔽参数,但没有令人满意的可用实验值。总而言之,具有最高辐射衰减的最佳质量比被确定为 [Na2Si3O7/Bi2O3(65/35)/B2O3(2)/Sb2O3(11)],因此玻璃复合材料可能是首选的辐射屏蔽在各种应用中。本研究中研究的四元玻璃复合材料的性能优于普通混凝土,接近纯铅作为辐射屏蔽。模拟和 BXCOM 结果表明,这些方法可用于确定玻璃复合材料的辐射屏蔽参数,但没有令人满意的可用实验值。总而言之,具有最高辐射衰减的最佳质量比被确定为 [Na2Si3O7/Bi2O3(65/35)/B2O3(2)/Sb2O3(11)],因此玻璃复合材料可能是首选的辐射屏蔽在各种应用中。本研究中研究的四元玻璃复合材料的性能优于普通混凝土,接近纯铅作为辐射屏蔽。模拟和 BXCOM 结果表明,这些方法可用于确定玻璃复合材料的辐射屏蔽参数,但没有令人满意的可用实验值。总而言之,具有最高辐射衰减的最佳质量比被确定为 [Na2Si3O7/Bi2O3(65/35)/B2O3(2)/Sb2O3(11)],因此玻璃复合材料可能是首选的辐射屏蔽在各种应用中。本研究中研究的四元玻璃复合材料的性能优于普通混凝土,接近纯铅作为辐射屏蔽。因此,玻璃复合材料在各种应用中可能更适合用作辐射屏蔽。本研究中研究的四元玻璃复合材料的性能优于普通混凝土,接近纯铅作为辐射屏蔽。因此,玻璃复合材料在各种应用中可能更适合用作辐射屏蔽。本研究中研究的四元玻璃复合材料的性能优于普通混凝土,接近纯铅作为辐射屏蔽。
