This package includes a set of advanced analysis algorithms for further processing of gamma spectra acquired. These algorithms provide a complete analysis of gamma ray spectra obtained from any type of gamma detector. The program is based upon time proven methodologies that have a long history of acceptance and refinements, and it includes patented1, ground-breaking analysis and calibration techniques. The gamma analysis algorithms supplied are accessible from the Genie 2000 interactive environment, the batch procedure environment or the S560 Programming Libraries. Analysis execution utilizes data resident in the Configuration Access Method (CAM) data structures native to all Genie Family systems.
