Abstract

This article summarizes the use of accelerator mass spectrometry (AMS) for radiocarbon dating measurements. It expands on the principles already laid out in the articles on Principles of Radiocarbon Dating and 00040. The great advantage of AMS is that it allows dating of very small, sub-milligram (<0.5 mg C) samples of carbon to routine precisions of about 0.3% (±24 radiocarbon years). Higher precisions, down to about 0.2% can be obtained by longer counting times or multiple measurements.
