Study of Some Shielding Parameters of Gamma Rays and Fast Neutrons for Various Shielding Materials

In this paper, some of the shielding parameters for gamma rays like linear attenuation coefficient, effective atomic number, half value layer, and removal cross section of fast neutrons were calculated for polymer composite consisted of polystyrene as basic material (PS) and various reinforced materials (B, B2O3, clay) with different reinforced concentration (5, 15, 25, 35, 45) %. X-Com program was used to calculate the values of gamma attenuation coefficient at various energies (0.5, 1, 3, 5, 7) Mev. Results have been shown that with increasing of reinforced materials concentrations, the linear attenuation coefficient, removal cross section, and effective atomic number increase while half value layer decrease, and when the energy increase, linear attenuation coefficient decrease while half value layer and effective atomic number increase.
