A procedure for the sequential determination of radionuclides in soil and sediment samples

We present a new radiochemical procedure for the sequential determination of Sr, Am, Pu, Th and U radionuclides. For the validation, seven IAEA certified reference materials were analyzed for 239 Pu, 240 Pu, 241 Pu, 238 U and 232 Th isotopes by ICP-MS, 243 Am by alpha spectrometry and 90 Sr by low l...

Summary:We present a new radiochemical procedure for the sequential determination of Sr, Am, Pu, Th and U radionuclides. For the validation, seven IAEA certified reference materials were analyzed for 239 Pu, 240 Pu, 241 Pu, 238 U and 232 Th isotopes by ICP-MS, 243 Am by alpha spectrometry and 90 Sr by low level gas proportional counting. The sequential method was then used for determining the radionuclide profiles in one sediment core collected in the River Rhine, near Augst, downstream of the Swiss nuclear power plants.
