Contract Description:

The Environment Group of the ILL’s Health Physics, Safety and Environment Service is responsible for the Institute's environmental radiation monitoring. This involves the analysis of field samples in its laboratory. The Environment Group analyses tritium activity on various matrices (water, tritium as gas or vapour in the air, free tritium in milk and plants). As part of the renewal of its instrumentation, the Group is planning to acquire a liquid scintillation counter.

About the measurement:

  • The measuring system must be based on two photomultipliers recording double coincidences, coupled to a multichannel analyser.
  • Energy scales to be measured: from 0 to 2MeV minimum.
  • Quenching measurement using the external standard method.
  • Minimum sensitivity of 50% for an unquenched tritium sample.
  • Acquisition of a measurement spectrum and definition of regions of interest for counting.
  • Background count for an inactive unquenched sample of less than or equal to 3 cpm for an energy range of 0 to 18 keV in 150 minutes.
  • Automatic and manual configuration of regions of interest in the count spectra for tritium, carbon-14 and nickel-63.
  • Detection of luminescence in the samples and/or ability to signal and correct it. Capacity to signal or correct electrostatic interference.
  • Detect and signal any lack of homogeneity in the sample/cocktail.
  • Substract background based on predefined samples.
  • Management of the samples awaiting measurement, using

About the results :

  • Output of results configurable by protocol directly to network printer and/or to file.
  • Protocol for configuring layout and content of the results sheet.
  • Software for visualising the count spectra and the analysis.
  • Monitoring over time of the calibration sources (possibility to produce a control card).
  • Results available in cpm and dpm.
