WebRadiocarbon 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 ∼5730 years, although by convention … Web10 jan. 2024 · While radiocarbon dating is useful only for materials that were once alive, scientists can use uranium-thorium-lead dating to measure the age of objects such as …
