Radiocarbon Dating at the ANU - (14C) measurement

The next stage in Carbon-14 Dating at The Australian National University has commenced. With the successful ARC LIEF grant in 2005 a state of the art Single Stage Accelerator Mass Spectrometer from the National Electrostatics Corporation of Middleton , Wisconsin has been delivered, tested and accepted. This new stage in Carbon-14 Dating at the ANU follows on the heels of the very successful liquid scintillation counting laboratory for Carbon-14 Dating that was commissioned in 1965 and the AMS Carbon-1 4 dating in the 1990 ' s. Collaborative projects ranging from archaeological dating, soil carbon studies, atmospheric CO 2 content, ocean circulation and climate change are being undertaken. Recent instrumental advances will enable the measurement of very small samples using a CO 2 gas capable ion source.
