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