Abstract
A selective method is described for the determination of Pb-210 in sed iments, based on the separation of the daughter Bi-210 by extraction c hromatography with Microthene 710-tri-n-octylphosphine oxide (TOPO) an d on a final source counting with a low background beta-counter. The a verage chemical yield is 92.0%. The detection limit for 2 g samples is 19 Bq kg(-1) An IAEA reference sediment sample was analyzed to check the reliability of the method.
