Carbon 14 dating correction curve


Nearly a decade after Willard Libby’s initial work to develop this method, the half-life was revised from 5,568 to 5,730 years.This meant that many calculated dates in papers published prior to this were incorrect.



This is the radiocarbon accelerator in Oxford, where I work, and it’s a £2.5 million piece of kit that enables you to date really small pieces of bone, really small pieces of charcoal.So for those of you that know a little bit about it, radiocarbon has a half-life of 5,568 years.That means that, every 5,568 years, half the radioactive carbon in the bone, or the charcoal that we find in an archaeological site, has decayed back to its parent isotope, nitrogen-14.Learn about developments in radiocarbon dating in our Athol Rafter heritage scientist timeline PROF TOM HIGHAM My expertise is in dating and archaeological dating using radiocarbon.
