Abstract
In this study, glass composition based on tungsten oxide (WO
) doped tellurium, titanium glasses: (100 −

) TeO
TiO
WO
: where (
= 5) and (
= 5, 10, 15, 20, 25) coded as TT
, TT
, TT
, TT
, and TT
were investigated for shielding properties against ionizing radiation. Gamma radiation shielding parameters such as mass attenuation coefficients (MAC) are calculated through MCNPx code and Phy-X/PSD software in the energy range of 0.015–15 MeV. Obtained MAC values are then used to calculate other gamma radiation shielding parameters such as mean free path (MFP) and effective atomic number (
). Besides this, the exposure buildup factor (EBF) was also calculated by using EXABCal software at different penetration depths (PDs) in the energy range of 0.015–15 MeV. Sample TT
, which has a larger WO
content of 25 mol% shows higher values of MAC and lower values of MFP among all the examined glass samples. Our investigated TeO
–TiO
–WO
glass samples possess the lowest MFP values in comparison with the different types of concretes and commercially available shielding glasses. In addition, fast neutron shielding characteristics in light of fast neutron removal cross-section have also been computed. Glass sample TT
possesses the higher values of fast neutron removal cross-section as compared to the other glass samples. The results indicate that the adding up of WO
improves shielding against the fast neutron and gamma radiation.
