Validation of the ImageJ package for alpha track counting on Solid State Nuclear Track Detectors

Abstract

In the present work, an alpha spectroscopic method using CR39 nuclear track detectors is being evaluated, elaborating on track parameters from different alpha particle sources. The freely-available, Java-based ImageJ software was used to obtain the major and minor axis length, the area and the mean gray level of the recorded tracks. A multi-paramater approach based on Principal Component Analysis of the data was subsequently applied and succeeded in grouping the recorded tracks according to alpha-particle energy. The methodology was further applied for the separation of radon progeny on CR39 detectors exposed in a radon chamber.

“…This comprehensive approach ensured a thorough investigation of the tracks and facilitated the collection of a considerable amount of data for subsequent analysis. We employed ImageJ software to facilitate the examination and analysis of the tracks (Bator et al, 2015;Alexandropoulou et al, 2019;Frutos-Puerto et al, 2021). Due to the high density of tracks observed within each field and the need to apply specific visibility criteria such as circularity and track diameter, the software implemented a customized macro.…”
