The optical absorption of high lead borate and lead silicate glasses containing manganese before and after γ‐ray irradiation was studied. To separate the absorption due to manganese from the intrinsic absorption, blank glasses were prepared and measured. The results showed that the visible absorption band before and after irradiation exhibited changes with the radiation dose and chemical composition of the glass. The response of the glasses to gamma irradiation was related to the creation and spread of defect “color centers,” the approach of a saturation condition, and the possible photochemical effect on the transition metal.
