Changes in optical properties transparency of pure and cobalt oxide (CoO)-doped lithium borate glasses have been investigated for fresh and γ-irradiated samples. These changes either in the transparency or color due to the variation of Co concentration or γ-irradiation doses indicated changes occurred inside the glass matrix. The ability of this glass to shield gamma ray, neutron, electrons, and protons was also examined. The calculations of optical band gap values showed a decrease, with the increase in CoO concentration, while the refractive index increased. Mass attenuation coefficient (MAC) of glasses was measured at 662, 1173, 1275 and 1333 keV energies by utilizing NaI(Tl) detector; also, theoretically by using Phy-X/PSD program derivative gamma shielding parameters have been studied. It was found that an increase in CoO % makes increment of gamma attenuation. Moreover, adding CoO improves neutron absorption due to the bigger cross section of Co atoms. Charged particles as (proton and electron); glass samples give good results at 10 keV‒10 MeV kinetic energy range computed by SRIM code. This paper provides complementary results to the authors of previous research studies that examined this glass as an electron beam irradiation dosimeter.
