List mode data acquisition for Compton continuum suppression

Abstract

This research uses the portable HPGe and NaI(Tl) detectors for Compton continuum suppression.In the List mode data acquisition technique, we did not use timing module and complicated experimental setup that recorded the time stamp of each event. The maximum suppression factor (SF) in Cs-137 point source was 3.8. By using this technique, we can detect samples that contain very low radioactivity. The experimental setup in this research was based on analog nuclear electronic modules. The study's main goal was the ability of list-mode data acquisition in Compton continuum suppression. In this way, lower levels of radioactivity can be detected in any sample.
