In this work, a quick and simple low-level radionuclide metrology technique for the traceable measurement of Rn-222 activity concentration in drinking water using a 0.56 l ionisation chamber operating in spectrometric pulse mode has been developed, tested, verified and applied to 16 water samples successfully. The impact of essential influencing factors on the result has been investigated, discussed and considered in the uncertainty budget of the measurement method. Finally, the new method has been assessed regarding the applicability on the EU Council Directive 2013/51.
