The radiation shielding effects and elastic properties of adding lead (Pb) and bismuth (Bi) to glasses was analyzed. Six different glasses, coded as G1-G6, were simulated with varying compositions of bismuth oxide and lead oxide, with G1 having the lowest density and G6 having the greatest. MCNP-5 code was used to calculate the mass attenuation coefficient, half value layer, tenth value layer, and mean free path of the glasses, the latter of which was compared with other radiation shields. These parameters were investigated between 0.015MeV and 15MeV. The bond compression model was utilized to analyze various parameters that describe the elastic properties of the glass samples. From the ultrasonic wave measurement result, the substitution of PbO and Bi2O3which working as a network modifier towards SiO2glass systems would break up the Si–O–Si bonds along with all the formation of non-bridging oxygen's which give the impact in the elastic moduli analysis of the glasses. |
