Abstract
‎This study focuses on the ability of both ZnO and Gd2O3 used as doping agents in glass in order to replace shielding for lead purposes‎. ‎The choices of metal-transition oxide and rare earth oxide doping aim to compare shielding results‎, ‎given their different properties‎. ‎A thermal study of two series of Zinc oxide and Gadolinium oxide in different percentages is performed‎. ‎The radiation attenuation properties of these doped glasses were developed‎. ‎Experimental measurements were performed using a photon spectrometer‎. ‎Photons incident from Co-60 and Cs-137 sources with main energies of 662‎, ‎1173‎, ‎and 1332 keV were applied to the shield‎. ‎This study demonstrated that adding either Gadolinium oxide or Zinc oxide to medical glass enhances the radiation attenuation ability‎, ‎with a preference given to Gadolinium Oxide glass doping‎. ‎In terms of radiation attenuation‎, ‎the results obtained with Gadolinium Oxide are comparable to those obtained with lead oxide-doped glass‎. ‎In addition to the attenuation factors‎, ‎the thermal properties of each of the mentioned samples were studied under temperature changes‎.
