Optical density for CN-85 and CR-39 Plastic Detectors and α-Particle Radiography

Abstract

Optical density has been measured for CN-85 and CR-39 plastic detectors that irradiated withhigh doses of α-particle. It was found that the rising of optical density to its maximum value happensfor CN-85 detector in a shorter etching time than that required for CR-39 .And by increasing the α-particle dose, the optical density peak appeared at earlier etching time . It found in this work thatplastic track detectors are good candidates for α-particle radiography
