Radiocarbon dating also referred to as carbon dating or carbon 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 s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of 14 C it contains begins to decrease as the 14 C undergoes radioactive decay. Measuring 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 calculate when the animal or plant died.

This Portable C14 Device Will Revolutionise Field Archaeology | DigVentures

The Radiocarbon Dating Laboratory in Lund performs dating on geological and archaeological samples. We also measure 14C in modern samples for determination of biomass content in e. Radiocarbon dating is based on the radioactive decay of 14C in dead tissues, which can be used to calculate the time that has elapsed since death occurred. This is possible since organisms have the same 14C content as the environment in which they live.

This Portable Carbon-Dating Device Is Going To Revolutionise Field Archaeology

British Broadcasting Corporation Home. Radio carbon dating determines the age of ancient objects by means of measuring the amount of carbon there is left in an object. In , he won the Nobel Prize for Chemistry. This is now the most widely used method of age estimation in the field of archaeology. Certain chemical elements have more than one type of atom.
