title: An easy method to determine 210Po and 210Pb by alpha spectrometry in marine environmental samples.
abstract: Two 210Po measurements by alpha spectrometry are made in two different aliquots separated by sufficient time for the growth of 210Po from the 210Pb content to be significant, as a difference from other methods that prepare consecutively, the two sources from the same aliquot. The main advantage is that this method is more rigorous than others, as it avoids possible error sources in the radiochemical procedure and takes care of uncertainties and their propagation. Analyses of bivalve samples have validated the method.
