Description

A program with the aim of dating water from economically-important Australian groundwater basins was initiated at the ANU in late 1985. In order to span the anticipated time scale, the content of the radioisotope 36Cl in the water must be determined with a sensitivity of about one part in 1015. Accelerator mass spectrometry is the only method capable of such ultra-sensitivity. The work reported has concentrated on an evaluation of the 14UD accelerator facilities for this purpose, and measurements have been made in order to demonstrate the feasibility of the technique and to establish the requirements for routine, accurate measurements
