Abstract: This study presents a rapid and novel sequential separation strategy based on extraction chromatography for determining Sr-90, Pb-210 and Po-210 in drinking water samples. It involves the use of Sr resin for the separation and then liquid scintillation counting and alpha spectrometry for the determination. The experimental results obtained showed that the proper acidic solution to quantitatively retain the aforementioned radionuclides is 3 M HNO3. The optimum eluents were determined for obtaining quantitative recoveries (70-80%) of Sr-90, Pb-210 and Po-210. The method was validated with intercomparison water samples and is satisfactory in terms of minimum detectable activities, which are 50% lower than that established in RD 314/2016.
