TrueCoinc 1.5

TrueCoinc, developed at the Institute of Experimental Physics, University of Debrecen, is a specialized software tool for evaluating and correcting true-coincidence summing effects in gamma-ray spectrometry. It helps laboratories achieve accurate photopeak efficiencies and activity determinations, especially in close geometries or when measuring nuclides with complex decay schemes.

Key capabilities:

• Calculates nuclide- and geometry-specific true-coincidence summing correction factors for high-resolution detectors (e.g., HPGe), accounting for both summing-in and summing-out.
• Models realistic measurement conditions, including source-to-detector distance, detector response characteristics, sample geometry, and self-attenuation.
• Builds emission cascades from evaluated nuclear decay data and supports user-edited decay schemes for specialized applications.
• Integrates into efficiency calibration and activity quantification workflows, producing correction tables and machine-readable outputs.
• Estimates uncertainties based on input parameters to support defensible, traceable results and quality assurance.

TrueCoinc is designed for environmental radioactivity laboratories, nuclear metrology and standardization, activation analysis, safeguards, and other fields where precise gamma-ray spectrometry is essential. By providing reliable summing corrections, it reduces bias in reported activities and improves the comparability of measurement results across instruments and setups.
