- Abstract
Radioactive elements (H, Cl, Na, Sr and Ba) was used and measured in one of the in-situ experiments. The separation scheme had to be developed and optimized. Cl was first extracted by silver chloride precipitation and then Sr and Ba were extracted by Sr/Ba carbonate precipitation after which activities of H and Cl were measured by liquid scintillation counting while activities of gamma emitters (Na, Sr and Ba) were measured by gamma spectrometry from the initial solution. In the precipitation, the recoveries of Cl and Sr were 100 % while the recovery of Ba was about 85 %. The detection limit of H was 0.1 Bq g whereas the detection limit of Cl was 0.05 Bq g.
