MCNP Modeling of Attenuation Coefficients of Steel, Red brass, Pearl and Beryl in comparison with Experimental and XCOM Data

In this research, MCNP model for studying mass attenuations coefficients for steel, Red brass, Pearl and Beryl at 661.6, 1173.2 and 1332.5 keV photon energies is investigated. The simulated results of mass attenuation coefficients were compared with the experimental and XCOM results. The results indicate that this process can be followed to determine the data on the attenuation of gamma rays with the several energies in different materials. The modeling for photon interaction parameters was standard for any type of composite samples.
