Alpha detection of 210Po and 210Pb using 10-20L seawater
| Sample Type | Water |
|---|---|
| Elements | Pb Po |
| Radioisotopes | 210Pb, 210Po |
| Detection by | alpha | Description | This method specifies the minimum requirements and laboratory methods for the analysis of 210Po and 210Pb in seawater samples with alpha-spectrometry. Samples are collected in acid-cleaned container and co-precipitated with Fe(OH)3 in the presence of Pb and 209Po yield tracers. Po isotopes are auto-plated onto silver disks on board. Post processing take place in the land laboratory by separating residual Po from Pb and auto- plating 210Pb-generated 210Po. Po isotopes are measured by alpha-spectrometry. Corrections on ingrowth and decay are included in calculating the in situ 210Po and 210Pb activities |
