Abstract

Thecurrent researchelucidatesthenuclearshieldingcapacityofgerminatetelluriteglasses: 41.7GeO2–41.7TeO2–16.6Ga2O3,37.5GeO2–62.5TeO2,10.4GeO2–72.9TeO2–16.7Ga2O3and12.5 GeO–87.5TeO2. Gamma-ray photon, fast neutron and electron shielding parameters of the present glassy materials were evaluated and studied via the Geant4Monte Carlo, Phy-X/PSD software, ESTAR and analytic computations. In addition, Makishima–Mackenzie’s theory was applied to assess the elastic properties of the studied tellurite glass systemcontainingGa2O3 and/or GeO2. The effective atomic number of the glasses varies from19.14to44.08for41.7GeO2–41.7TeO2–16.6Ga2O3,20.63–48.02for37.5GeO2–62.5TeO2, 21.15–48.15 for 10.4GeO2–72.9TeO2–16.7Ga2O3 and 22.42–50.29 for 12.5GeO2–87.5TeO2. The obtained fast neutron removal cross sections of the glasses were 0.0991, 0.0966, 0.1024and0.1021cm−1,respectively,for41.7GeO2–41.7TeO2–16.6Ga2O3,37.5GeO2–62.5TeO2, 10.4GeO2–72.9TeO2–16.7Ga2O3 and 12.5GeO2–87.5TeO2.
