The influence of gamma radiation on the electro-optical properties of CR-39 polymer has been investigated by capacitive and interferometric measurements to see the order and tendency of irradiation effects on polymer CR-39, which is commonly used in track detectors. Seven samples of thickness 760 gm and other dimensions 25 mm x 25 mm have been exposed to gamma radiation in the range of zero to 70 kGy in 10 kGy steps. Experimental results exhibit radiation-dependent degradation even at relatively low doses. Modulation of electronic properties can be exploited as an alternative diagnosis tool.
