Key Features

  • Measurement of volumetric activity of gammaemitting radionuclides in process liquids in nuclear facilities
  • Suitable for high temperatures 
  • Monitor type ATL - monitor detector is attached to the measured pipeline
  • Optionally can provide safety classified function, category C, according to the EN 61226 standard
  • In-built Cs-137 check source


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:

  • gamma detector, including high  temperature gamma scintillator NaI(Tl) Ø 1“ × 1 “,
  • 10 mm thick lead collimator,
  • check and stabilization source Cs-137 with the activity of 16 kBq,
  • radiation processing unit RPU-04 with a 1024- channel analyser for the processing of data from the detector.
