Composite samples of compositions (X-70) (SiO2): X(Bi2O3): 30(3CaO.SiO2) were synthesized and studied for their ra*diation shielding properties. The density of each sample was measured using digital densimeter. The densities of the samples were found to increase as the quantity of bismuth oxide (Bi2O3) increases. The linear attenuation coefficient (LAC), mass attenuation coefficients (MAC), half value layer (HVL), tenth values layer (TVL), mean free path (MFP) of the samples were calculated from the experimental data. The results reveal that the values of LAC and MAC consistently decrease while the values of HVL, TVL and MFP increase steadily as the photon energy increases suggesting a good material for radiation shielding. The sample with 25 % of Bi2O3 suggested the most effective for radiation attenuation. This study highlights the possibility of locally obtained materials that are readily available and cost effective for viable radiation shielding applications as a worthwhile alternative to the conventional lead-based shielding materials.
