【 摘 要 】

In this paper, mass attenuation coefficients of different granite samples are calculated at662, 1173 and 1332 keV photon energies by using Monte Carlo code MCNPX (version2.4.0). The obtained numerical results are compared not only with previous experimentaland theoretical studies but also with standard theoretical data. The results showed thatMCNPX results from generated simulation input agreed well with experimental studiesand previous investigations. In addition, numerical deviation values of the massattenuation coefficients in three photon energies has been obtained minimum betweenMCNPX andtheoretical data. The comaparative results underlined R-squared value forMCNPX approach out performs compared to both experiemental results and GATEmodel. Our results showed that, MCNPX is significantly convenient in comparison toGEANT4 for the energy range used. The results obtained from validated simulation inputhave been used for the calculation of some other important shielding parameter such ashalf value layer (HVL). It can be concluded that, standard simulation geometry would beuseful for scientific community and MCNPX can be used as a powerful tool where noanalogous experimental data exist for investigating shielding materials used in nuclearfields, industrial fields and high-energy radiation therapy facilities.
