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 (Zeff), and exposure buildup factor (EBF) were calculated for gamma rays between 0.015 and 15 MeV.
