Nuclear safeguards inspections require definitive isotopic identification of nuclear materials under field conditions. HPGe gamma-ray spectroscopy provides the energy resolution necessary to separate closely spaced emissions from special nuclear materials, enabling confident identification that lower-resolution detectors cannot achieve.

The ISOTAC quantitative assay module computes calibrated isotope activities from field spectroscopy data, providing in-situ NDA results without access to a counting laboratory. ANSI N42.42 reachback file formats allow data sharing with inspection teams and analysis centers.

The GeGI gamma-ray imager extends safeguards capability to spatial source distribution mapping, allowing inspectors to identify the location and spatial extent of nuclear material using Compton and pinhole imaging from a single field position without moving the detector.
