Comparison of photon attenuation coefficients of various barite concretes and lead by MCNP code, XCOM and experimental data

In this study shielding properties of various barites concretes and lead in three high gamma energies 0.662, 1.173, and 1.332 MeV were investigated using the MCNP-4C code and compared with predictions from the XCOM code and experimental data. In the three selected energies, the simulated and available data values were compared and results showed a good agreement. The results of the three methods show that lead, and pure (100%) barite have higher linear attenuation coefficients and lower transmission factors and mean free path values relative to 50% barite and 0% barite concretes.
