Triathler Becquerel Finder

For large volume gamma counting

Easy-to-use screening instrument for nuclear accidents

  • Easy-to-use
  • Flexible
  • Large volume up to 1 L
  • Small size and weight make Triathler ideal for personal use on a benchtop or for on-the-spot field/sea measurements.
  • A keypad allows single key operation for immediate results using preset protocols for any isotope.

Optimised for detection of radioactive isotopes in the event of a nuclear emergency

The instrument is equipped with an external NaI(Tl) detector with enlarged lead shield which facilitates the use of Marinelli beakers with total sample volume of 1L. This enables rapid detection of I-131, Cs-134 and Cs-137 in foodstuff, water and milk.

Optionally, a standard Triathler Liquid scintillation counter can be equipped with the Triathler Becquerel finder detector. This combination provides a useful tool for detection of both alpha, beta and gamma emitters.
