Abstract
The application of shielding is one of the main protective measures in ionizing radiation safety. This paper addresses the influence of erbium oxide (Er2O3) amount fraction on shielding properties of the glass system with compound formula 75TeO(2)-10Nb(2)O(5)-10ZnO-5PbO (TNZP). Addition of Er2O3 portions increased samples densities from 5.57 to 5.65 g/cm(3). The attenuation properties for the different TNZP-Er2O3 samples were simulated using Phy-X/PSD software at vary wide energy ranged from 0.015 to 15 MeV. Various radiation shielding parameters were evaluated including; linear (LAC) and mass (MAC) attenuation coefficients, the half (HVL)- and tenth (TVL)-value layers, the mean (MFP) free path, the total atomic (ACS) and electronic (ECS) crosssections and fast (FNRCS) neutron-removal cross-section. These parameters were also verified by a comparison with the currently available shielding materials such as RS-253-G18, RS-360, RS-520 and, Chromite, Ferrite, Magnetite, and Barite. Morover the strong green and weak red emission estimated in the prepared glasses under excited 980 nm Results show that TNZP with high Er2O3 constituents is not merely an effective shield for photons but also a good candidate for neutrons protection and theraputic surgery for medical diagnostic applications. The provided exults showed lower FNRCS values compared to the Chromite, Ferrite, and Magnetite. Nevertheless, it can be noticed that the partially added density of Er2O3 enhanced FNRCS.
