Detection of 234Th in 4 Liter seawater
| Sample Type | Water |
|---|---|
| Elements | Th |
| Radioisotopes | 234Th |
| Detection by | beta | Description | A method is described for the analysis of 234Th in 4 L seawater samples. 234Th is pre- concentrated with MnO precipitates and filtered in 25mm QMA filters. Dried filters are measured at sea or onshore using beta counting system. Chemical recoveries are determined measuring 230Th by ICP-MS, and are usually >90%. |
