Abstract

The influence of short-term heating or cooling and exposure to visible light on the bleaching of a gamma-irradiated glass stored at 20°C is investigated by photometry. The decay of radiation-induced color centers is retarded under the action of heating and gradually regains its initial rate after the heating ceases. The transient stage can be described as relaxation. It is revealed that isothermal photobleaching does not exhibit a similar aftereffect.
