The NERC Radiocarbon Facility (East Kilbride) is a central facility for the UK's Natural Environment Research Council (NERC), providing dating support in the environmental sciences.
The laboratory has an "open-door" policy for all existing and potential users of its facilities at all stages of their research projects, and collaboration is strongly encouraged.
Definition: AMS (Accelerator Mass Spectrometry) radiocarbon dating is a way to obtain radiocarbon dates from samples that are far tinier than that needed for standard radiocarbon dating.
Standard c14 dates require amounts of between 1 and 10 grams of charcoal; AMS can use as little as 1-2 milligrams, and under special circumstances to samples as small as 50-100 micrograms.
Fossilized Siberian mammoth remains are important indicators of environmental change in the Late Pleistocene.
The NSF-Arizona AMS Laboratory radiocarbon results on amino acid separations compare well with mammoth bone collagen from the same specimens treated by HCl and dated by beta counting (the Russian Academy Geological Institute Radiocarbon Laboratory).
New methods are developed and tested as necessary to meet specific dating needs and to improve the overall accuracy and precision of the lab.
Radiocarbon dating by accelerator mass spectrometry (AMS) is an important analytical method utilized in climate change, land use change, ecosystems and natural hazards research.
