Study the Effect of Gamma-Ray and Annealing on the Optical Absorption of Glass

A study of Gamma-ray effects on the optical absorption of glass for a range of wavelengths ( 300-900 ) nm with doses varied between (0.331-2.65) Mrad. The effect of annealing treatment on the optical absorption within the range of (50-400)C has been also studied, then the calibration line for measuring the irradiation dose for Gamma-ray on the glass was established. Two models were used to measure the activation energy at fixed annealing time (0.25) hr.
