A soda-lime-silicate glass is exposed to beta radiation from an Sr-90 source and gamma radiation from a (CO)-C-60 source. Under exposure to radiation of the Sr-90 and Co-60 radioisotopes, the glass changes its color depending on the irradiation doses. The effect of beta irradiation on the optical properties of the glass is compared with that of gamma irradiation. The optical properties of the irradiated glasses differ significantly from those of the unirradiated glasses. Under exposure to beta and gamma radiation, the three main optical absorption bands appear at similar to 380-460, similar to 620, and similar to 1050 nm. It is established that the absorption band at similar to 420 nm, which is attributed to Fe3+, ions, is very sensitive to beta and gamma irradiation.
