In 1949, American chemist Willard Libby, who worked on the development of the atomic bomb, published the first set of radiocarbon dates.

In recent years, a few of these methods have come under close scrutiny as scientists strive to develop the most accurate dating techniques possible.The latter have generally been available only since 1947.Many absolute dating techniques take advantage of radioactive decay, whereby a radioactive form of an element is converted into a non-radioactive product at a regular rate.How It Works: Carbon has 3 isotopic forms: Carbon-12, Carbon-13, and Carbon-14.The numbers refer to the atomic weight, so Carbon-12 has 6 protons and 6 neutrons, Carbon-13 has 6 protons and 7 neutrons, and Carbon-14 has 6 protons and 8 neutrons.
