The monitor is designed to measure the presence of gamma radionuclides in technological circuits of nuclear facilities.

The monitor consists of:

  • The detector GD-52, based on a gamma detector NaI(Tl) 2.5 "x 2.5" (proper function of the detector can be checks by built-in test LED),
  • RPU-12 Data Acquisition and Processing Units with one, optionally two, 1024 Channel Analyzers (MCA) to evaluate data from detector.

The RPU determines the total volumetric activity of gamma radionuclides in the fluid flowing through the conduit.
