TLDR
A method for 210Po and 210Pb determination in water samples is described in this article, where the nuclides are concentrated, in presence of added 208Po and lead carrier, by evaporation.Abstract:
A method for210Po and210Pb determination in water samples is described. The nuclides are concentrated, in presence of added208Po and lead carrier, by evaporation. Then the polonium is plated electroless from the acidic solution on a copper planchet and measured by alpha spectrometry.210Pb separation from the other isotopes is based on the solutility of PbSO4 in citrate.210Pb content is determined by measuring the activity of its daughter210Bi. The critical steps in the isolation of lead have been examined and discussed.read more
