Prediction of mechanical and radiation parameters of glasses with high Bi2O3 concentration

This study aims to perform multidirectional characterizations on nuclear shielding efficiencies some bismuth-based glasses. Accordingly, the γattenuation coefficients for xBi2O3-(75-x)B2O3–25Li2O (x = 0, 10, 20, 30, 40, 50, 60 70 mol%) were widely evaluated using simulations and theoretical methods. Linear attenuation coefficient (LAC) of glasses was obtained by Monte Carlo general-purpose simulation code FLUKA compared with XCOM database up 15 MeV. Moreover, LAC values have been utilized evaluate related parameters like mass (MAC), total molecular cross-section (σt), atomic (σa), half-value layer (HVL), electronic (σe), mean free path (MFP), effective number (Zeff), electron density (Neff). The results noted that data are in great agreement. Relatively higher (5.818 g/cm3), greater LAC, MAC, Zeff, lower HVL, MFP achieved 70Bi2O3-5B2O3–25Li2O glass. this glass sample is a better gamma shield.
