PGIS-2.

Portable Gamma-Ray Spectrometer

The instrument is designed for portable or backpack application of radiation detection and monitoring in a variety of environments. The system is auto-calibrated by natural photo peaks, consisting of a detector unit, integrated with GPS, and a data logger unit based on Android portable devices, such as a tablet or a notebook. The detector can be equipped with a Nal(TI) crystal of various volumes ranging from 0.347 liter up to 2 liters.

Benefits.

  • Recording of full spectra
  • Real dose calculation from spectra
  • RIID
  • Automated synchronisation of data with GPS
  • Real-time display of measures data
  • Identification of man-made radionuclides
  • Light-weight, portable and user-friendly device
  • Built-in Navigation function
