Aviation gamma spectrometer "GS-9"


The aviation gamma spectrometer "GS-9" is a complex of several autonomous devices with their own power supply. The field of application is ecology, radioecology, aerogeophysical service, radiological services, monitoring of ground, airspace and terrain, from various ground mobile means or from aircraft, with flight characteristics satisfying the requirements for spectral information collection, as well as in stationary mode.


The gamma radiation of radionuclides is detected by a detection unit located in a heat-resistant waterproof container.

The spectrometric information from the detection unit is recorded on the internal memory of the device and extracted at the end of the research.

The use of algorithms for processing instrumental spectra implemented in PC software allows obtaining data on radioisotope composition and volumetric activity for individual radionuclides.

Gamma-spectrometers "GS-9" are available in four versions

  • "GS-9C" - Scintillation detector NaI (Tl) Ø150x100 mm, spectrometer control with display on the                device itself
  • "GS-9D" - Scintillation detector NaI (Tl) Ø150x100 mm, control spectrometer with a laptop
  • "GS-9E" - Scintillation detector NaI (Tl) Ø200x100 mm, spectrometer control using the display on the device itself
  • "GS-9F" - Scintillation detector NaI (Tl) Ø200x100 mm, control spectrometer with a laptop
