“…In the 1980s the accuracy of activity determination using the LS counter was considerably improved by applying one particular model for calculation of the counting efficiency [24][25][26]. The model, based on the statistical description of physical phenomena occurring in the LS counter, was derived from earlier work [23,27,28] and is summarized hereafter.…”

Liquid scintillation counting (LSC) techniques can be used for radionuclide standardization when the calculation of detection efficiency is possible. This is done using a model of the physicochemical processes involved in light emission and also of the statistics of photon emission: the free parameter model. This model can then be applied in two ways: by deducing the free parameter from the measurement of a tracer (the CIEMAT/NIST method) or by calculating this free parameter from coincidence ratio in a specific LS counter (the TDCR method). The purpose of this paper is to describe both these models and some practical issues that need to be addressed if LSC is to be effectively used in radionuclide metrology.
