Abstract

In the present investigations, structural and optical variations in PM-355 solid state nuclear track detector are studied at different doses, 20, 40, 60, 80 and 100 kGy of gamma radiation. Effects of gamma radiation on pre and pose alpha irradiated samples of P-355 at the same dose are also studied. Structural and surface variations are studied using XRD patterns and micrographs of scanning microscope. Optical properties are investigated using UV-Vis spectrograph and spectrofluorometer from JASCO. It has been observed that the absorbance of PM-355 material increases with increasing gamma dose and saturated at 60 kGy. Moreover, the variation in the structure and optical properties saturate at 60 kGy of gamma rays. It is also concluded that PM-355 can be good candidate for gamma dosimetry up to 60 kGy radiation..
