Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. The Wikibook Historical Geology has a page on the topic of: The results were summarized in a paper in Science inin which the authors commented that their results implied it would be possible to date materials containing carbon of organic origin.
