Optical density of the etched alpha-tracks in CR-39 nuclear track detector

摘要

An optical method is presented for alpha spectroscopy by measuring the optical density of etched CR-39 samples irradiated with different alpha particle energies. The relation between the optical density per track, alpha energy and etching conditions were studied using a simple experimental setup. An empirical formula to calculate the stopping power of alpha particles in a CR-39 detector is proposed in this study. (C) 1998 Elsevier Science Ltd. All rights reserved. [References: 5]
