ABSTRACT

Halloysite is a clay mineral found in the natural environment and it has many applications in chemistry and medical fields. The linear attenuation coefficient (µ) for halloysite nanotubes minerals simulated using MCNP 5 code between 0.015 and 15 MeV. Moreover, the linear attenuation coefficient calculated for all selected samples using Phys-X/PDS program. Furthermore, some important shielding parameters that described the penetration and interaction of gamma rays with halloysite atoms, such as the half-value (HVL), effective atomic number (Z_eff), and exposure buildup factor (EBF) were calculated for gamma rays between 0.015 and 15 MeV.

埃洛石是一种在自然环境中发现的粘土矿物，在化学和医学领域具有许多应用。使用MCNP 5代码在0.015和15 MeV之间模拟的埃洛石纳米管矿物的线性衰减系数（µ）。此外，使用Phys-X / PDS程序为所有选定样本计算的线性衰减系数。此外，还计算了一些重要的屏蔽参数，这些参数描述了伽玛射线与埃洛石原子的渗透和相互作用，例如半值（HVL），有效原子序数（Z _eff）和曝光累积因子（EBF），它们之间0.015和15 MeV。
