Polaris-H | H3D Gamma | WMD Detector Selector

General Description
Polaris-H was developed for nuclear power plants as a complete solution for the identification, quantification, and localization of gamma-ray sources. It is a battery-operated system that weighs less than 10 pounds, with an integrated optical camera to overlay the gammaray image for each isotope the system identifies. The energy resolution is near 1% FWHM at 662 keV, and the detector can localize gamma-ray sources in all directions simultaneously. It is ready to use within two minutes of pressing the power button. It is airtight and watertight for easy decontamination. A tablet connects wirelessly for real-time display of the spectrum and image some distance away. The detector technology is 3D-position-sensitive CdZnTe (CZT).

Technical Description
The system is an imaging gamma spectrometer based on 3D-positionsensitive CdZnTe (CZT). This allow each gamma interaction to be located within the detector. This along with the energy measurement allows for the direction of the incoming photon to be calculated in real time. This information is displayed over a registered visual image to provide an energy selected view of the gamma emissions in the environment.
