✦ Synopsis

The track registration properties of CN-85 and CR-39 plastic track detectors have been investigated under the Influence of uv. irradiations.

The length and width of the etched tracks increase considerably due to u.v. absorption m the solid state nuclear track detectors.

Post-irradiated CR-39 and CN-85 detectors show more U.V. sensitization than the pre-irradiated ones. The pre-irradiated CN-85 detectors.

however, exhibit no significant enhancement in the sensitization.

while CR-39 renders pronounced effect in both the modes. One can speculate that u.v. is preferentially absorbed in the damaged regions of the detectors.
