The SUERC Radiocarbon Laboratory is involved in archaeological, forensic and environmental research, additionally using stable isotopes (13C and 15N) for dietary reconstruction.

As well as undertaking its own in-house and collaborative research, the SUERC Radiocarbon Laboratory also provides a radiocarbon dating service to national and international museums, universities and archaeology units.

As a chronology tool, C dating can provide ages for samples as old as 50,000 years.

The small sample size capability of AMS radiocarbon dating greatly expands the potential for dating geologic material previously undateable using older proportional counting methods.

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.

AMS dates are therefore more precise and require smaller samples.

Established analytical procedures for radiocarbon dating are carefully applied to every sample the laboratory processes.
