  • The Rafter Radiocarbon Databases and Archive contain radiocarbon submission, treatment and measurement data spanning 70 years. The Rafter Radiocarbon Lab manages the digital databases, paper records and physical remains of submitted materials. All ~60,000 results reported by our laboratory since 1951 are digitised and available on request. Most gas counting results were reported prior to the implementation of the current radiocarbon reporting conventions and therefore we strongly recommend that users of our gas counting results contact us to obtain recalculated results that follow the current reporting conventions. For early samples, details of sample provenance and preparation are archived as paper records and access to these may incur a charge. AMS results can usually only be provided with permission of the original submitter. Full details are available digitally with permission. Contact radiocarbon@gns.cri.nz for data access.
