Abstract


The fission fragments and heavy ions tracks in CR-39 detectors registered by Cf-252 radioactivesource have been observed by using photo-spectrometric techniques. CR- 39 detectors were exposedat 5 cm distance from radioactive source for registering nuclear tracks created by nuclear particlesemitted from Cf-252 radioactive source. Cr-39 detectors were etched in 6N NaOH solution at 70oCfor 400 minutes in the intervals between 20 to 25 minutes. The etching properties of CR-39, irradiatedby ultra violet radiation has been examined. In un-etched condition, it is found that the transmittanceis nearly 95% and in etched condition the transmittance decreases up to 72% due to the change intrack densities inside CR-39 foils.
