How is carbon dating done?
They are then able to: Is therefore a very large amount of the carbon dating methods. Since this rate is slow relative to the movement of carbon through food chains from plants to animals to bacteria all carbon in biomass at earth's surface contains atmospheric levels of 14 C. However, as soon as any carbon drops out of the cycle of biological processes - for example, through burial in mud or soil - the abundance of 14 C begins to decline.
After years only half remains. After another years only a quarter remains.
This process, which continues until no 14 C remains, is the basis of carbon dating. A sample in which 14 C is no longer detectable is said to be "radiocarbon dead. They are derived from biomass that initially contained atmospheric levels of 14 C. But the transformation of sedimentary organic debris into oil or woody plants into coal is so slow that even the youngest deposits are radiocarbon dead.
The abundance of 14 C in an organic molecule thus provides information about the source of its carbon. If 14 C is present at atmospheric levels, the molecule must derive from a recent plant product. The pathway from the plant to the molecule may have been indirect or lengthy, involving multiple physical, chemical, and biological processes. Levels of 14 C are affected significantly only by the passage of time.

Experiments that would eventually lead to carbon dating began in the s, thanks to the efforts of the Radiation Laboratory at the University of California, Berkeley. At the time, researchers were attempting to determine if any of the elements common to organic matter had isotopes with half-lives long enough to be of value in biomedical research.
By , the half-life of Carbon 14 was determined, as was the mechanism through which it was created slow neutrons interacting with Nitrogen in the atmosphere. Korff published in which predicted that C 14 would be created in the atmosphere due to interactions between nitrogen and cosmic rays. From this, Libby came up with the idea of measuring the decay of C 14 as a method of dating organic material.
In , Libby moved to the University of Chicago, where he began the work that would lead to the development of radiocarbon dating. In , he published a paper in which he speculated that C 14 might exist within organic material alongside other carbon isotopes. After conducting experiments, which measured C in methane derived from sewage samples, Libby and his colleagues were able to demonstrate that organic matter contained radioactive C- This was followed by experiments involving wood samples for the tombs of two Egyptian kings, for which the age was known.
Their results proved accurate, with allowances for a small margin of error, and were published in in the journal Science. In , Libby received the Nobel Prize in Chemistry for this work.
