Keywords: Borate glass, Lutetium, Radiation shielding properties.


The glasses with composition xLu2O3-20Na2O-(80-x)B2O3, where x = 5, 10,15 and 20 mol% concentration variations of Lu2O3, were measured shielding radiation properties at different photon energies from 1 keV-100 GeV by using WinXCom software program. The values of mass attenuation coefficient, effective atomic
number and electron density were found to increase with increasing energy and Lu2O3 content. The comparison results of glass systems with ordinary and hematiteserpentine concrete in terms of mass attenuation coefficient, half value layer, mean free bath and Removal cross sections for fast neutrons to test the accuracy of glass systems are about radiation protection. The results indicate that glass systems can
be developed as radiation shielding materials.
