The optical reflection, transmission, and UV/VIS- absorption spectra had been recorded in the wavelength(200-500nm) for PM-355 before and after irradiation with γ-ray irradiation by using 60Co-dose within range of(30-160Mrad) at normal conditions. The absorption spectra of irradiated samples showed radiation induced absorption changes by photodegradation. There was an increment in absorption proportional with irradiation dose. The optical constants (α,Kex,n,εi,εr,Eg,) were calculated for all samples. The effect of irradiation on the optical constants of the PM-355 before and after irradiation had been investigated.
