Abstract
A new procedure for the determination of uranium, thorium and Ra-226 from t he same aliquot of an aqueous sample using extractant scintillators and liq uid scintillation alpha spectrometry is proposed, The procedure is designed such that the same aqueous phase can be used in all the stages, with sligh t modifications. The procedure is thus very simple, requiring little manipu lation of the sample. Testing of the procedure was performed obtaining sati sfactory results and high reproducibility, (C) 2000 Elsevier Science Ltd, A ll rights reserved.
