Photon and Neutron Characterization of Titanium Neodymium Tellurite Glass Doped WO3

Abstract

This study investigates the photon and neutron attenuation properties of a glass system comprising [(89- x)O₂+10TiO₂+1Nd2O₃+xWO₃], where x=0, 10, and 20 mol%. Utilizing Phy-X and XCOM programs, the mass attenuation coefficient was  determined in the energy range 0.015 to 15 MeV. The results show that the mass attenuation coefficient at 0.015 MeV increased by 6.66%  and 12.74% with the addition of 10 mol% and 20 mol% WO₃, respectively. Similarly, The HVL of the glass samples decreased by 6% and  16% with the addition of 10 mol% and 20 mol% WO₃, respectively. The exposure buildup factor and energy absorption buildup factor  decreased with increasing WO₃ content and increased with penetration depth. Notably, the fast neutron removal cross-section of TW20  surpasses that of some standard shielding materials. These findings suggest that the TW20 glass sample, with highest WO₃ content,  exhibits promising gamma and neutron shielding applications.
