Chi tiết:  Radioactive contamination control of water and bottom sediments at depths up to 500 meters with GPS-referencing.

  • Determination of spatial position of detection device during measurement
  • Cable reel with a current feedthrough
  • Display of measurement results on index maps of controlled radionuclides concentration or gamma radiation dose rate distribution
  • Expert mode for instrument spectrum analysis with automatic identification of sample radionuclide content
  • Expert "GARM" software for further data processing and analysis, and radiological mapping
