Sincescientists have reckoned the ages of many old objects by measuring the amounts of radioactive carbon they contain. This page has been archived and is no longer updated. Radioactive material gets a bad rap, what with radiation and fallout and nuclear waste and all. Since the early twentieth century scientists have found ways to accurately measure geological time.

Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.
Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. Rachel Wood does not work for, consult, own shares in or receive funding from any company or organisation that would benefit from this article, and has disclosed no relevant affiliations beyond their academic appointment. Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life. Cart 0. Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms.
