Mechanical and Gamma-Ray Interaction Studies of PbO–MoO3–Li2O–B2O3 Glass System for Shielding Applications in The Low Energy Region: A Theoretical Approach

The mechanical and radiation shielding properties for the PbO–MoO3–Li2O–B2O3 glass system were theoretically investigated in this paper. (coded as glasses) was fabricated using melt quenching mechanism. optical packing density (OPD) increases from 75.563 to 84.366, oxygen molar volume (OMV) decreases 13.234 11.853 cm3/mol when increasing PbO concentration. values of elastic moduli decreased 47.06 39.67 GPa Young, 33.51 32.41 bulk, 19.82 16.29 shear 59.94 54.14 longitudinal is increased. attenuation characteristics reported at photon energies used diagnostic radiology. mass coefficient (MAC) evaluated three photoatomic data libraries EPICS2017, EPDL97, XCOM, available EpiXS Phy-X programs. MAC five glasses 20 keV much higher than 40, 60 80 keV. increased with addition PbO, Pb-S1 demonstrating lowest MAC, Pb-S5 highest MAC. Additionally, rate increment concentration that effective atomic number (EAN) determined program.
