Optical density for CN-85 and CR-39 plastic detectors and α-particle radiography

Abstract EN

Optical density has been measured for CN-85 and CR-39 plastic detectors that irradiated with high doses of α-particle.

It was found that the rising of optical density to its maximum value happens for 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 that plastic track detectors are good candidates for α-particle radiography.
