Developments in AMS of 99 Tc

Wacker, L.; Fifield, L Keith; Tims, Stephen


Sample preparation and AMS methodology for 99Tc have been refined with the aim of improving sensitivity to permit measurements on as little as 0.25 l of seawater. Sample preparation improvements have been directed towards minimizing 99Ru and maximizing the yield of the 99TcO- ion from the ion source. A range of chemical extraction techniques and the purity of various reagents have been explored. In order to monitor the chemical yield, the γ-emitting isotope 95mTc (T1/2=61 days), produced by the...[Show more]
