PHDS GeGI Gamma-Ray Detector features a wide-angle optical camera combined with a gamma-ray imaging spectrometer that quickly and accurately captures the nuclear environment. Compton imaging helps GeGi in obtaining both close range and targets at a further distance. A 90 x 11mm HPGea(60ccm) is present. Its mechanical cooler eliminates the need for liquid cooling. In various project spaces, automatic isotope detection, recognition, localization, and source action quantification are made available to users of all levels.
Features of GeGI Gamma-Ray Detector:
- Standoff location detection identification distance range 10 cm – 50 + metres.
- Automatically specifies SNM, NORM, IND, MED.
- Germanium gamma-ray spectroscopy (16k ch).
- Full 360° standoff visualization (Compton), 235U (186 keV), 239Pu (375 keV, 414 keV).
- User-friendly single-button glove-touch operation.
