Investigation of Structural and Radiation Shielding Parameters for Lead Pyrophosphate Glasses

Abstract

We have elaborated the Na 2 O-(1-x)PbO-xCuO-P 2 O 5 , with (0 ≤ x ≤ 1), us-ing a conventional melt quenching technique. The object of the present investigation is an analysis of the relationship between the structure and gamma ray shielding properties of the studied compounds. The Raman spectroscopic study showed that the substitution of Pb 2+ by the Cu 2+ ions leads to a large modification in the structure of (P 2 O 7 ) 4 groups. Additionnaly, we have investigated the gamma ray shielding properties of elaborated glasses. Using the XCOM software, mass attenuation coefficients (μ/ ρ ), half value layers (HVL) and effective atomic numbers (Z eff ) were calculated. The values of μ/ ρ and Z eff were found to decrease with the increase in CuO content. The results show that Cu 2+ ions affect the structure and gamma ray shielding properties of the glasses systems Na 2 O-(1-x)PbO-xCuO-P
