The lead element or its salts are good radiation shielding materials. However, their toxic effects are high. Due to less toxicity of bismuth salts, the radiation shielding properties of the bismuth salts have beeninvestigated and compared to that of lead salts to establish them as a better alternative to radiationshielding material to the lead element or its salts. The transmission geometry was utilized to measure themass attenuation coefficient (m/r) of different salts containing lead and bismuth using a high-resolutionHPGe detector and different energies (between 81 and 1333 keV) emitted from point sources of 133Ba,57Co, 22Na, 54Mn, 137Cs, and 60Co. The experimental m/r results are compared with the theoretical valuesobtained through WinXCOM program. The theoretical calculations are in good agreement with theirexperimental ones. The radiation protection efficiencies, mean free paths, effective atomic numbers andelectron densities for the present compounds were determined. The bismuth fluoride (BiF3) is found tohave maximum radiation protection efficiency among the selected salts. The results showed that presentsalts are more effective for reducing the intensity of gamma photons at low energy region.
