Some phosphate glass samples containing 30 mol% blast furnace slag (as iron industrial waste) and 20 mol% heavy metal oxides (cadmium and lanthanium) have been prepared by the melt quenching method. It was found that as La2O3 was gradually increased at the expense of CdO, gamma-ray attenuation coefficient increased while the half value layer decreased. Density and molar volume as well as the number of oxygen ion density increased gradually also. From the obtained data, it appeared that, these glasses act as suitable gamma-ray shield especially at high energies. The samples exhibit also semiconductor properties and have mixed conduction mechanisms of both CBH and SPH models. The electrical conductivity showed a decrease with the gradual increase of La2O3 content.
