Reimer, Tim Heaton, The Conversation. Geological and archeological records offer important insights into what seems to be an increasingly uncertain future. The better we understand what conditions Earth has already experienced, the better we can predict and potentially prevent future threats. Our research, published today in the journal Radiocarbon , offers a way to do just that, through an updated method of calibrating the radiocarbon timescale. Radiocarbon dating has revolutionized our understanding of the past.

The Center for Applied Isotope Studies offers consultation and full radiocarbon dating services for research and commercial clients. We use the latest techniques and technologies. Our state-of-the-art Pretreatment and Graphitization Facility allows us to offer many specialty services, including micro-sampling and compound-specific dating. We are experts in dating extremely small and poorly preserved samples. The Center for Applied Isotope Studies is and always has been a tracer-free facility: we do not accept, handle, graphitize or count samples containing Tracer or Labeled Hot 14 C due to the risk of cross-contamination. Standard turnaround time is 3 weeks.
RADIOMETRIC TIME SCALE
Carbon 14 C , or radiocarbon , is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues to date archaeological, geological and hydrogeological samples. Its existence had been suggested by Franz Kurie in The primary natural source of carbon on Earth is cosmic ray action on nitrogen in the atmosphere, and it is therefore a cosmogenic nuclide.
