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.
Aug 02, The radiocarbon dating of unique bone, ivory or antler artefacts (e.g. perforated batons, Venuses from the European Upper Paleolithic or emblematic fossil Cited by: Feb 09, Radiocarbon dating relies on the carbon isotopes carbon and carbon Scientists are looking for the ratio of those two isotopes in a sample. Most . Radiocarbon dating lab Beta Analytic provides fast high-quality AMS dating results in business days. The lab also provides stable isotope analysis.

Jul 18, Therefore, radiocarbon dating of SOM is necessary, but unfortunately not straightforward. Dating of fractions of SOM obtained by alkali-acid extraction is promising, but which fraction (humic acid or humin) renders the most accurate 14 C dates is still subject to debate.
