According to Wikipedia, Radiocarbon 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, who received the Nobel Prize in Chemistry for his work in 1960. It is based on the fact that carbon- 14 is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting carbon-14 combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire carbon-14 by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of carbon-14 it contains begins to decrease as the carbon-14 undergoes radioactive decay. Measuring the amount of carbon-14 in a sample from a…
