摘要：
The effect of swelling in CR-39, during the etching process has been studied using 'thickness-measurement' method. The values of the bulk etch-rate (V-B) determined by this method have been corrected in the context of irreversible swelling produced in various CR-39 samples. The results have been compared with those obtained using the 'mass-measurement' as well as the 'fission fragment track diameter' methods. The values of experimental VB have been obtained by taking the arithmetic average as well as by fitting the Gaussians to the results of a number of CR-39 samples. It is shown that the 'thickness-measurement' method is as good as the other methods of determining the bulk etch-rate provided sufficiently large number of CR-39 samples are used for obtaining the mean value from the Gaussian fit of the experimental data.
