The 1995 IAEA intercomparison of γ-ray spectrum analysis software

In an intercomparison organized by the IAEA, 12 PC-based programs for γ-ray spectrum analysis were tested using seven reference spectra and a sum of squared differences method. It was found that all programs yield peak areas without bias, relative to each other. Most of the programs could analyze a spectrum containing only singlets in reasonable statistical control with respect to peak areas. Peak positions generally are reported with too small or absent uncertainties. Statistical control was found to be lacking in the analysis of doublet peak areas.
