210Po and 210Pb from 5-10 L using Fe(OH)3 coprecipitation
| Sample Type | Water |
|---|---|
| Elements | Pb Po |
| Radioisotopes | 210Po, 210Pb |
| Detection by | alpha | Description | This method specifies the minimum requirements and laboratory methods for the analysis of total 210Pb and 210Po in seawater samples. Samples are collected in acid-cleaned containers and pretreated on board, by acidifying and co- precipitating the samples. Post processing will take place at the home laboratory by auto- plating of Po isotopes onto silver disks on a 1 M HCl solution. Po isotopes emissions are finally measured by alpha spectrometry. Isotope ingrowth and decay corrections are applied to calculate the 210Pb activities. |
