Polaris-H is a gamma camera from H3D using compton scattering and operates without a collimator. The gamma-rays incoming to the detector are tracked as the scatter inside. Mathematical algorithms are used to retrace the paths of the gamma rays within the detector, and the results reveal the direction of the source. Polaris-H is a portable complete solution for the identification, quantification, and localization of gamma-ray sources at nuclear power plants.

  • Routine monitoring and maintenance
  • Decommissioning operations
  • Emegencies, incidents and outages
