Assessment of protective properties of glasses with the application of golmium oxide against Gamma radiation

An assessment of the radiation-protective parameters of glass samples with different ratios of holmium oxide Ho2O3 was carried out using a system of libraries for computer modeling of the processes of passage of elementary particles through the Geant4 substance and the NIST XCOM database. The results of calculations of the mass attenuation coefficient and the half-attenuation layer for the samples under study at the energy of gamma radiation varying from 0.122 to 1.408 MeV are presented.
