The shielding of γ-rays by concretes produced with barite

The concretes produced with barite (BaSO4) were studied as shieldingmaterials for γ-radiation. The concretes were prepared with different volumes of barite, and thus each concrete has different density and aggregate. The mass attenuation coefficients have been calculated at photon energies of 1 keV to 100 GeV using XCOM and the obtained results were compared with the measurements at 0.66 and 1.25 MeV. The barite concrete results were also compared with ordinary concretes.
