A NOVEL RADIATION SHIELDING MATERIAL FOR GAMMA-RAY: THE DEVELOPMENT OF LUTETIUM LITHIUM BORATE GLASSES

This work, gamma-ray shielding properties of the lutetium lithium borate glasses in the system Lu2O3 - Li2O - B2O3 have been evaluated as a shielding material at 662 keV photon energy. While the experimental mass attenuation coefficients (μm) have been determined by using the narrow beam transmission method, the theoretical data were calculated using WinXCom program. The good agreements between experimental and theoretical values have been obtained. Both experimental and computational mass attenuation coefficients data were used to obtain the effective atomic number (Zeff), and the effective electron density (Nel). Based on the obtained data, the Lu-based glasses have good shielding properties, the improved glasses could be used as gamma-rays shielding material.
