The monitor is designed to measure the 88Kr radionuclide in the coolant of the primary circuit of a nuclear reactor, which is released into the coolant only in case of fuel cell leaks.

The monitor consists of:

  • GD-52 based on 2.5 "x 2.5" NaI(Tl) gamma detector (correct probe functionality can be checked by built-in test LED),
  • Sandwich shielding GD-52 (lead, tin, copper) near the pipeline with the measured liquid,
  • Stainless steel cooler GD-52, through which the coolant flows (ensuring that the maximum working temperature of the detector is not exceeded),
  • RPU-12 Data Acquisition and Processing Units with 1024 Channel Analyzer (MCA) to evaluate data from the detector.


  • LAD-08 Liquid Activity Detector
