Although in situ gamma spectroscopy is not new, recent developments in rugged/reliable/portable Ge detectors, small powerful PCs, small all-digital portable MCAs, and versatile/accurate mathematical efficiency calibrations have made this a very powerful tool. There are many ways in situ spectroscopy can be used to save time and money and get more accurate results in D&D and ER projects. Various applications, as performed by the >100 ISOCS (In Situ Object Counting System) users include:
- Free-releasing of complex shaped objects
- Activity-depth profiles in concrete or soil
- Underwater measurements of hot items
- Location and activity of buried/hidden sources
- Activity in sealed tanks or pipes
- Field sample assay
