Exposure of polycarbonate detectors to high γ- ray doses causes a great effect on their structural. Samples of Makrofol DE 1-1 nuclear track detectors (NTDs) were irradiated with gamma doses in the range of 1-100 kGy using 1.25 MeV 60Co source of dose rate 4 kGy/h. The optical characterization of these detectors have been studied through the measurements of UV-visible absorption spectra of blank and γ- irradiated samples. The UV-visible spectra of γ- irradiated samples revealed color centers in the range (310-320 nm). Direct and indirect allowed optical band gap energies, refractive index (n), the number of carbon atoms per conjugated length (N), and the number of carbon atoms per cluster (M) for pristine and γ-irradiated samples were determined. Results revealed that optical band gaps decrease, while n, N, and M increase with increasing of γ-irradiated doses. This study sheds light on the basis of γ-interaction mechanisms with the polymeric detectors and use of Makrofol DE 1-1 in gamma dose determination.
