Evaluation of the Radiation Shielding Properties of a Tellurite Glass System Modified with Sodium Oxide.

In this study, the X-ray and gamma attenuation characteristics and optical properties of a synthesized tellurite-phosphate-sodium oxide glass system with a composition of (85 - x)TeO-10PO-xNaO mol% (where x = 15, 20, and 25) were evaluated. The glass systems we re fabricated by our research group using quenching melt fabrication. The shielding parameters of as-synthesized systems, such as the mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), effective atomic number (Z), half-value layer (HVL), tenth value layer (TVL), mean free path (MFP), and effective electron density (N) in a wide energy range between 15 keV and 15 MeV, were estimated using well-known PHY-X/PSD software and recently developed MIKE software.

The Effect of ZnO, MgO, TiO, and NaO Modifiers on the Physical, Optical, and Radiation Shielding Properties of a TeTaNb Glass System.

Novel glass samples with the composition 75TeO-5TaO-15NbO-5x (where x = ZnO, MgO, TiO, or NaO) in mole percent were prepared. The physical, optical, and gamma radiation shielding properties of the glass samples were studied over a wide energy spectrum ranging between 0.015 and 20 MeV.
