Paula J. Tim Heaton receives funding from the Leverhulme Trust via a research fellowship on “Improving the Measurement of Time via Radiocarbon”. Geological and archaeological 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 revolutionised our understanding of the past. It is nearly 80 years since Nobel Prize-winning US chemist Willard Libby first suggested minute amounts of a radioactive form of carbon are created in the upper atmosphere.
Libby correctly argued this newly formed radiocarbon or C rapidly converts to carbon dioxide, is taken up by plants during photosynthesis, and from there travels up through the food chain. When organisms interact with their environment while alive, they have the same proportion of C as their environment. Once they die they stop taking in new carbon. Their level of C then halves every 5, years due to radioactive decay.
