Abstract
The effect of UV irradiation from (a) an ordinary UV lamp, (b) a spark source and (c) the sun on the track length of
252Cf fission fragments and
132Xe ions has been studied. It has been observed that the etched track length varies considerably for the UV exposed detectors. The light transmission properties of UV and charged particle exposed detectors have also been studied and compared to see the modifications introduced in the structure. The changes show that the modifications in these cases possess more or less similar patterns.
