Radiocarbon dating has allowed key transitions in prehistory to be dated, such as the end of the last ice age , and the beginning of the Neolithic and Bronze Age in different regions. Beta Analytic does not accept pharmaceutical samples with "tracer Carbon" or any other material containing artificial Carbon to eliminate the risk of cross-contamination. In , Martin Kamen and Samuel Ruben of the Radiation Laboratory at Berkeley began experiments to determine if any of the elements common in organic matter had isotopes with half-lives long enough to be of value in biomedical research. For example, if a series of radiocarbon dates is taken from different levels in a given stratigraphic sequence, Bayesian analysis can help determine if some of the dates should be discarded as anomalies, and can use the information to improve the output probability distributions. More broadly, the success of radiocarbon dating stimulated interest in analytical and statistical approaches to archaeological data. 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 14 C , a radioactive isotope of carbon.
Libby was awarded the Nobel Prize in Chemistry in recognition of his efforts to develop radiocarbon dating.

These results were published in Science in Deep time Geological history of Earth Geological time units. This is probably because the greater surface area of ocean in the southern hemisphere means that there is more carbon exchanged between the ocean and the atmosphere than in the north.

- In these cases a date for the coffin or charcoal is indicative of the date of deposition of the grave goods, because of the direct functional relationship between the two. This led to estimates that the trees were between 24, and 19, years old,  and hence this was taken to be the date of the last advance of the Wisconsin glaciation before its final retreat marked the end of the Pleistocene in North America.
