For tritium detection, liquid scintillation counters have been classically employed, in which the energy of a tritium decay is transferred to a scintillant molecule in solution which in turn gives off photons whose intensity and spectrum can be measured by a photomultiplier array. Radiation physics and health. The sample is not exposed to a beam of electrons but detectors picks up the expelled electrons from the radionuclei. The half-life of carbon is 5, years.
