A new sequential cloud point extraction (CPE) procedure was developed and validated for the determination of 210 Pb and 210 Po by ICP-MS/MS and alpha spectrometry, respectively. Two distinct CPE systems using 4',4''(5'')-di- tert -butyldicyclohexano-18-crown-6 and N , N , N ', N '-tetraoctyldiglycolamide as chelating agents were performed sequentially on the same sample. Method detection limits of 13 and 3.5 mBq L -1 , were achieved for 210 Pb and 210 Po, respectively. The sequential approach shows its outstanding versatility and proficiency to rapidly extract, detect, and quantify both radionuclides in various matrices for a wide range of activities.
