Assessment of radiation exposure to drinking, surface, and groundwater and of the associated health risks calls for accurate and precise  226 Ra and  222 Rn measurements. One method that fits the bill is liquid scintillation counting (LSC), which allows measurements in one-phase (homogenous) or two-phase samples. The aim of our study was to compare the measurement efficiency with both variations in Niška Banja spa water, known for its elevated  222 Rn content to get a better insight into the stability and behaviour of the samples and  226 Ra interference in samples spiked with  226 Ra with  222 Rn measurement.  226 Ra interference was more evident in homogenous, one-phase and much lower in two-phase samples. However, one-phase samples offer more accurate indirect  226 Ra measurements. Water-immiscible cocktails (in two-phase samples) have shown a limited capacity for receiving  222 Rn generated by Ra decay from the aqueous to organic phase when  222 Rn/ 226 Ra equilibrium is reached. We have also learned that samples with naturally high  222 Rn content should not be spiked with  226 Ra activities higher than the ones found in native samples and that calibration of two-phase samples can be rather challenging if measurements span over longer time. Further research would require much lower  226 Ra activities for spiking to provide more practical answers to questions arising from the demonstrated phenomena.
