WebRadiocarbon 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.
