Nuclear radiation shielding behavior for prepared LNZP glasses doped with (CdO+Te)

Abstract

Composition of 5Li2O-(40-x) Na2O-xZnO-55P2O5 doped with 2 wt% (CdO + Te) where (x = 0, 7, 14, 21, 28, 35 and 40) mol% glass system have been prepared and simulated for their gamma-ray shielding properties. The studied glasses were labeled as LNZP0–LNZP6 according to the values of Na2O and ZnO. Mass attenuation coefficient (MAC), Linear attenuation coefficient (LAC), half-value layer (HVL) and mean free path (MFP) have been calculated by the Phy-X/PSD software program in the photon energy range from 0.015 to 15 MeV. The results show that the highest values of MAC were 30.64, 31.98, 33.34, 34.62, 35.89, 36.82 and 38.09 cm2/g at the energy 0.015 MeV for LNZP0-LNZP6 glass samples, respectively. Also, atomic cross section (ACS), electron cross section (ECS), effective atomic number (Zeff) and electron density (Neff) have been estimated. The results showed that the LNZP6 glass sample has the best gamma-ray protection properties among other examined glasses. The ACS and ECS parameters were found to have the maximum value at 0.015 MeV and decreased with increasing energy of photons for all samples. The Maximum values of Zeff were at the energy 0.04 MeV equal to 48.92, 48.72, 48.56, 48.37,48.19, 48.02 and 47.85 for LNZP0-LNZP6, respectively.
