About the report

The Environmental Radioactivity Group (EnRad) of the Supervising Scientist Division (SSD) has undertaken a comprehensive calibration of their High Purity Germanium (HPGe) gamma spectroscopy system. Three detectors have been calibrated for five different geometries (sample types) holding sample masses of less than a gram up to 150 grams. This IR documents the calibration procedure, the methods of calculation and the results of the system calibration.
