摘要：
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.
