Radiocarbon dating - Wikipedia
In 1939, Martin Kamen and Samuel Ruben of the Radiation Laboratory at Berkeley began experiments to determine if any of the elements common in organic matter had isotopes with half-lives long enough to be of value in biomedical research. They synthesized C using the laboratory's cyclotron accelerator and soon discovered that the atom's half-life was far longer than had been previous…
