The Radiation Shielding Parameters of a Standard Silica Glass System

We investigated the radiation shielding parameters for K 2 O-SiO 2 glasses using Phy-X software. The results show that the glasses with a higher K 2 O concentration and lower SiO 2 contents have higher mass attenuation coefficient (MAC) values at all energies. At 0.03 MeV, the MAC values of the test...

Description
Summary:We investigated the radiation shielding parameters for K 2 O-SiO 2 glasses using Phy-X software. The results show that the glasses with a higher K 2 O concentration and lower SiO 2 contents have higher mass attenuation coefficient (MAC) values at all energies. At 0.03 MeV, the MAC values of the tested glasses are varied between 0.873 and 1.907 cm 2 /g, while at 0.10 MeV they are in the range of 0.168-0.195 cm 2 /g. The linear attenuation coeffieicnet (LAC) shows a direct relation with the density, where the LAC for the glass with a density of 2.211 g/cm 3 is 0.704 cm -1 at 0.05 MeV and increases to1.351 cm -1 for the glass with a density of 2.491 g/cm 3 . We reported the effective atomic number (Z eff ) for the tested glasses and we found the glass with a composition of 40K 2 O-60SiO 2 has the greatest Z eff at all energies. The Z eff values at 0.03 MeV are in order of 11.94-16.43, while at 4 MeV they are varied between 10.06 and 12.31. according to the half value layer results, 40K 2 O-60SiO 2 glass has the lowest HVL, which means this glass has the best radiation shielding properties among the tested glasses.
