Impact of $ \mathrm{Eu_2}\mathrm{O_3} $ and $ \mathrm{Er_2}\mathrm{O_3} $ on the gamma radiation shielding performance of $ \mathrm{B_2}\mathrm{O_3} $+CaO+ZnO+BaO+$ \mathrm{Eu_2}\mathrm{O_3} $ + $ \mathrm{Er_2}\mathrm{O_3} $ glass system

In this study, four rare earth-doped BaO-ZnO-CaO- \mathrm{B_2}\mathrm{O_3} glass samples were prepared using melt-quenching technique. The density of the glass was determined using Archimedes' method and found in range 3.28-3.72 gcm^{-3} . The linear attenuation coefficient for the prepared glasses was measured experimentally at four energies 0.059 MeV, 0.662 MeV, 1.173 MeV, and 1.332 MeV emitted from ^{241}\mathrm{Am} , ^{137}\mathrm{Cs} , and ^{60}\mathrm{Co} gamma sources, respectively. The attenuation factors were calculated using Phy-X, and the relative deviation of the theoretical and experimental values ranged between 1.08 % and 6.54 %, indicating the reliability of the linear attenuation coefficient measurement for EuEr-X glass (65-x-y) \mathrm{B_2}\mathrm{O_3} -13BaO-6CaO-(16+y)ZnO-x \mathrm{Eu_2}\mathrm{O_3} -x \mathrm{Er_2}\mathrm{O_3} , where y = 0-12 mol % in 4 mol % increments and x =0.25-1 mol % in 0.25 mol % increments. The enhancement in linear attenuation coefficient with \mathrm{Er_2}\mathrm{O_3} , \mathrm{Eu_2}\mathrm{O_3} , and ZnO showed a clear energy dependence, where the increase in linear attenuation coefficient is more pronounced at 0.059 MeV relative to 0.662 MeV, 1.173 MeV, and 1.333 MeV. At 0.059 MeV, the linear attenuation coefficient improves by 44 %, while lower enhancement of 13-14 % is found in the energy range of 0.662-1.1333 MeV. Other shielding factors, such as half value layer Radiation shielding efficiency, were estimated. This glass structure can be considered a transparent protective shield for low-energy photons, especially in medical and nuclear applications.
