In 1988, a comparative evaluation of seven commercially available software packages for the analysis of low-level environmental gamma-ray spectra was performed. At that time it was determined that many of the packages did not contain all the features that were necessary for the accurate analysis of complex, low-level environmental samples. The evaluation concentrated on peak detection, noise and phantom-peak rejection, resolution of peak doublets, and nuclide identification. A new evaluation was conducted on updated versions of four of the previously evaluated programs and two additional programs from Canada and Germany. The evaluation involved the analysis of synthetic and actual spectral data, including an air filter containing debris from the Chernobyl accident. System requirements, accurate nuclide quantification and ease of operation are also reported. |
