In this video, she compares conventional and accelerator mass spectrometry AMS radiocarbon dating. AMS is faster and needs a much smaller sample, but is more expensive. Also shown are views of bone preparation at the Waikato Radiocarbon Dating Laboratory. The C decays with the beta particle, and you have some detection equipment and you count the Cs one by one. Accelerator mass spectrometry is not dependent upon the radioactive decay.

Community Archaeology Radiocarbon Dating Fund (CARD Fund)
Operating continuously since the early s, the CIO now houses the longest-running radiocarbon dating laboratory in the world. Radiocarbon dating can be used to determine the age of any carbon-containing material such as bone, wood or shell that is less than 50, years old. The CIO accepts samples for a variety of academic and publicly funded research projects, and our staff work closely with all submitters, advising them on sample selection, pretreatment and data interpretation. Overview Radiocarbon dates are obtained by measuring the ratio of the unstable isotope, 14 C radiocarbon , to the stable isotope, 12 C, in a sample. Radiocarbon is produced naturally, in the upper atmosphere, as a secondary product of the cosmic ray bombardment.
Beta Analytic – Radiocarbon Dating Since 1979
Arizona Accelerator Mass Spectrometry Laboratory focuses on the study of cosmogenic isotopes , and in particular the study of radiocarbon , or Carbon As a laboratory, part of its aim is to function as a research center, training center, and general community resource. Its stated mission is conducting original research in cosmogenic isotopes. This laboratory is used primarily to provide radiocarbon measurements. Hence, coverage in research areas is multidisciplinary.
Based in Miami, Florida, the Beta Analytic radiocarbon dating lab revolutionized the fields of archaeology and late quaternary geology. It took months and sometimes years to obtain carbon dating results. Beta Analytic was founded by Murry Tamers, Ph. Yale University , D.
