The monitor is intended for the measurement of volumetric activity of gamma radionuclides in liquids such as process waters in nuclear facilities during routine, accident and post-accident conditions.

The monitor assembly is composed of:

  • GD-51 gamma detector, including high  temperature gamma scintillator YAP Ø 1“×1,5“;
  • stainless steel flow-through measurement chamber with 60 mm diameter and 314 mm length,
  • 50 mm thick lead shielding,
  • check and stabilization source Cs-137 with the activity of 25 kBq,
  • radiation processing unit RPU-04 with a 1024- channel analyser for the processing of data from the detector.


  • LAD-07 Liquid Activity Detector
  • LAD-08  Liquid Activity Detector
  • LAD-64 Liquid Activity Detector
  • LAD-66 Liquid Activity Detector
