Comprehensive study of photon attenuation through different construction matters by Monte Carlo Simulation

• We measure mass attenuation of gamma rays through different materials.
• We model a design of a simple model using Geant-4 Monte Carlo Simulation for calculating mass attenuation of different composite materials.
• We compare the model with the theoretical calculation of NIST XCOM code.

The main goal of this work is focused on testing the applicability of Geant4 electromagnetic models for studying mass attenuations for different types of composite materials at 59.5, 80, 356, 661.6, 1173.2 and 1332.5 keV photon energies. The simulated results of mass attenuation coefficients were compared with the experimental and theoretical data for the same samples and a good agreement has been observed. 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.
