Abstract
This paper examines radiation-shielding abilities of oxyfluoro-tellurite-zinc glasses in the chemical form of AlF

–TeO
2
–ZnO under the substitution of AlF

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.
