Abstract

Evidence presented in the literature indicates that the sensitivity and stability of latent tracks in CR-39 is affected by the environmental conditions which the detector experiences both before and after the irradiation. Studies have been made to determine the magnitude of these effects in CR-39 with ion beams of 1H, 16O, 20Ne, 40Ar and 56Fe. Post-irradiation annealing studies were performed in air and vacuum. As a result, the beneficial effect of anti-oxidant doping of CR-39 on the stability of the material and of latent tracks was confirmed.

    These drying conditions were selected in order to enhance desorption of physically sorbed water from the CR-39 matrix, while not affecting its atomic structure. It should be noted that treatment at higher temperatures affects the bulk etch rate and causes annealing of nuclear tracks in CR-39 [20,21]. The mass of each detector was measured, both before and after etching, using an analytic Chyo balance with an accuracy of ±0.1 mg.
