Abstract
The gamma radiation protection parameter for the TeO2-LINbO3-BaF2-La2O3 network modified by Nb2O5/TiO2 in the present work. The following compounds have been examined: [77.53TeO(2)-7.31LiNbO(3)-4.16Nb(2)O(5)-10% BaF2-1.0La(2)O(3), sample code TSH1), [71.69TeO(2)-7.31LiNbO(3)-10BaF(2)-1.0La(2)O(3), sample TSH2] and [76.69TeO(2)-7.31LiNbO(3)-5TiO(2)-10BaF(2)-1% La2O3 and sample code TSH3]. Within this, we specify the criteria for shielding such as mass attenuation coefficients (mu(m)/rho), effective atomic numbers (Z(eff)), electron density (Ne), half-value layers (HVL), mean free path (MFP). The TSH3 glasses have a greater gamma-ray safety performance because of a higher value of HVL, (mu(m)/.), and MFP. The observed glasses display good gamma ray safety compared to used standard radiation-shielding materials, namely RS-360, and RS-520. Finally, the structure of these glasses investigates at wavenumber in the range 50 to 1200 cm(-1) by using Raman spectra.
