Carbon dating accuracy called into question after major flaw discovery

When news is announced on the discovery of an archaeological find, we often hear about how the age of the sample was determined using radiocarbon dating, otherwise simply known as carbon dating. Deemed the gold standard of archaeology, the method was developed in the late s and is based on the idea that radiocarbon carbon 14 is being constantly created in the atmosphere by cosmic rays which then combine with atmospheric oxygen to form CO2, which is then incorporated into plants during photosynthesis. When the plant or animal that consumed the foliage dies, it stops exchanging carbon with the environment and from there on in it is simply a case of measuring how much carbon 14 has been emitted, giving its age. But new research conducted by Cornell University could be about to throw the field of archaeology on its head with the claim that there could be a number of inaccuracies in commonly accepted carbon dating standards.

Radiocarbon dating—also known as carbon dating—is a technique used by archaeologists and historians to determine the age of organic material. It can theoretically be used to date anything that was alive any time during the last 60, years or so, including charcoal from ancient fires, wood used in construction or tools, cloth, bones, seeds, and leather. It cannot be applied to inorganic material such as stone tools or ceramic pottery. The technique is based on measuring the ratio of two isotopes of carbon.
