Radiocarbon dating is possible because of the existence in nature of the radioactive isotope 14 C (albeit in small quantities; the vast majority of natural carbon is composed of the stable isotopes 13 C and 12 C). This isotope has the advantages for the study of the human past of a conveniently long half-life (of ∼ years, although by convention radiocarbon results are calculated on the.
