Radiocarbon dating also known as carbon dating or carbon dating is a technique for determining the age of an organic object by utilising the properties of radiocarbon, a radioactive isotope of carbon. Willard Libby developed the method at the University of Chicago in the late s. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants via photosynthesis; animals then acquire 14C through plant consumption. When an animal or plant dies, it no longer exchanges carbon with its surroundings, and the amount of 14 C it contains decreases due to radioactive decay. Definition: The amount of 14 C in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to determine when the animal or plant died.
