Description
Summary:	This paper examines radiation-shielding abilities of oxyfluoro-tellurite-zinc glasses in the chemical form of AlF 3 –TeO 2 –ZnO under the substitution of AlF 3 by ZnO. Gamma-ray- and neutron-shielding properties were tested in terms of mass attenuation coefficient ( μ / ρ ), half value layer, mean free path, effective atomic numbers ( Z eff ), effective electron density ( N eff ) and removal cross-section (Σ R ). The μ / ρ values of the glasses were generated by Geant4 simulations over an extended energy range and then the generated data were confirmed via XCOM software. The results showed that both gamma-ray- and neutron-shielding efficiencies of the selected glasses evolved by substituting of AlF 3 by ZnO. Nuclear radiation-shielding abilities of the current glass systems were compared with that of some conventional shielding materials and newly developed HMO glasses. It can be concluded that oxyfluoro-tellurite-zinc glasses could be useful to design novel shields for radiation protection applications.
