title: Applying direct liquid scintillation counting to low level tritium measurement.
abstract: Different types of procedures could be applied to measure environmental tritium level, but usually all are based on measuring tritium concentration in extracted samples water by liquid scintillation counting techniques. There are two standard methods published for tritium measurement in aqueous samples. The recommended tritium activities for tritium standard solutions can be found in these reference procedures. This paper reports the results from a comparative study carried out for different tritium standard solutions, in order to measure the counting efficiency using liquid scintillation method.
