radiocarbon dating also referred to as carbon dating or carbon14 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 by willard libby who received the nobel prize in chemistry for his work in 1960 it is based on the fact that radiocarbon 14.
