NSRL works in collaboration with accelerator mass spectrometry (AMS) measurement facilities to provide state-of-the-art radiocarbon preparation and measurement services to the local University and Federal research communities. The lab also pursues in-house research on applications of 14C dating to climate change studies, calibration of the 14C timescale, and the use of 14C as a geochemical and geophysical tracer in the Earth system.
