Radiocarbon dating definition, the determination of the age of objects of organic origin by measurement of the radioactivity of their carbon content. A form of radiometric dating used to determine the age of organic remains in ancient objects, such as archaeological specimens, on the basis of the half-life of carbon-14 and a comparison between the ratio of carbon-12 to carbon-14 in a sample of the remains to the known ratio in living organisms. Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the university of chicago by willard libby, who received the nobel prize in chemistry for his work in 1960. Recent examples on the web using radiocarbon dating, booth and brück found that many britons were buried with small, curated keepsakes crafted out of the remains of family members.
