Description
This research explores the critical intersection of experimental and computational approaches in gamma-ray spectrometry using thallium-doped sodium iodide (NaI) detectors. Despite advances in detection technology, NaI scintillators remain fundamental tools in radiation analysis due to their exceptional light yield, optimal signal preservation, and practical advantages including cost-effectiveness and scalability.
Our study focuses on a comprehensive characterization of a SCIONIX 76B76/3 NaI detector through precise energy and efficiency calibration using multiple radioactive sources including cobalt-60, sodium-22, barium-133, and cesium-137. By establishing accurate calibration parameters, we create a foundation for bridging experimental results with computational modeling.
The research implements two leading Monte Carlo simulation platforms TOPAS MC (Geant4-based) and MCNPX to model particle transport and energy deposition within the detector. Through comparative analysis between experimental data and simulation outputs processed with ROOT framework, we evaluate the precision of these computational models and their capacity to reproduce real-world detector responses.
This integrated approach not only enhances our understanding of NaI detector characteristics but also demonstrates how historical scintillator technology continues to evolve through modern computational techniques, maintaining relevance in contemporary environmental and radiation research applications.
