Peak Area Consistency Evaluation in Gamma Spectrometry

Quantification of radionuclide activities in gamma spectrometry can be a challenging task. It depends on efficiency calibration, peak area calculation, nuclide decay data and correction factors, such as attenuation or true coincidence summing corrections. These quantities present significant challenges to an accurate analysis. is therefore desirable have way assessing the quality quantification that applied samples with unknown compositions. A verification self-consistency analysis one possible accomplishing this. In it calculate using information from multiple emission energies. This leads overdetermined system for which solution used look inconsistencies. By calculating recovered areas comparing these measured areas, outliers identified by resolving inconsistencies spectrum improved. consistency evaluation find incorrect shape missing interferences data, point peaks where calculation needs optimized. The performance method has been shown simple consisting three radionuclides are interfering each other well complex composition activities. will integrated into future version Genie 2000 Gamma Spectroscopy Software.
