N2 - In this work we studied the radiation shielding features of Li2O-Sb2O3-PbO-GeO2-Cr2O3 glass systems at different energies ranging from 0.284 to 1.33 MeV. The maximum linear attenuation coefficient (LAC) for the germinate glasses is in the order of 0.680-0.707 cm-1 and this is reported at 0.284 MeV, whereas the minimum LAC is observed at 1.33 MeV and varied between 0.159-0.166 cm-1. An increase in the LAC is found for these glasses due to the addition of Cr2O3, and the glasses coded as C5 (with 0.5 mol% of Cr2O3) has the highest LAC. The half value layer (HVL) of the selected glasses with different contents of Cr2O3 is investigated, and the results demonstrated that the HVL is small at low energies and ranging from 0.98-1.02 cm at 0.284 MeV and from 1.328-1.383 cm at 0.347 MeV. The maximum HVL is observed at 1.33 MeV and equal to 4.175 cm for C5 and 4.352 cm for C1. The tenth value layer (TVL) values for the present glasses were reported, and the results showed that as the density increases from 3.07 to 3.2 g/cm3, the TVL decreases from 3.388 to 3.256 cm at 0.284 MeV, and from 13.413 to 12.868 cm at 1.173 MeV.
