The use of scintillation material for counting the nuclear tracks on plastic detectors

Abstract

In this research, an advanced method was tested for counting nuclear traces on the surface of CR-39 plastic detectors using the ZnO scintillator. several methods were tested for coating zinc oxide on the surface of plastic detectors, and the repeatability and stability of the ZnO response were tested when exposing the plastic detectors to an alpha source Am-241 , the linearity of ZnO response with exposure time was verified and compared with the traditional microscopic method for counting alpha tracks on the detectors.

The obtained results showed that the response of ZnO was linear with exposure time, and the uncertainty of the repeatability test was around 10%, it could be concluded from these results that the proposed method could be considered as a promising for counting traces of alpha particles on the surface of plastic detectors
