And if the artifact is organic, like wood or bone, researchers can turn to a method called radiocarbon dating. Radiocarbon dating, or simply carbon dating, is a technique that uses the decay of carbon 14 to estimate the age of organic materials. This method works effectively up to about 58,000 to 62,000 years. Since its introduction it has been used to date many well-known items, including samples of the Dead Sea Scrolls, enough Egyptian artifacts to supply a chronology of Dynastic Egypt, and Otzi the iceman. Willard Libby at the University of Chicago developed the technique of radiocarbon dating in 1949. Libby estimated that the steady state radioactivity concentration of exchangeable carbon 14 would be about 14 disintegrations per minute dpm per gram. In 1960, Libby was awarded the Nobel Prize in Chemistry for this work.

Geochronology is radiocarbon dating methods have distinctly different advantages and how does radioactive isotope is the most people think that it seems likely that uses.
Radiocarbon Dating. History and Process Jessica Berti Radiocarbon dating is one of the most significant scientific discoveries of the twentieth century. With radiocarbon dating archeologists and other scientists no longer rely solely on relative ages and can spend time researching how and why things happened rather than when.

Achaeological Science - Radiocarbon Dating D. Walter - May, 2008 Radiocarbon dating—also known as carbon-14 dating—is a technique used by archaeologists and historians to determine the age of organic material. It can theoretically be used to date anything that was alive any time during the last 60,000 years or so, including charcoal from ancient fires, wood used in construction or tools, cloth, bones, seeds, and leather. It cannot be applied to inorganic material such as stone tools or ceramic pottery. The technique is based on measuring the ratio of two isotopes of carbon.
