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.
In 1939, 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.

It is based on the fact that radiocarbon ( 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.van der Plicht, for Windows, upgraded with latest calibration data set (intcal04). ] Fairbanks Marine Radiocarbon Reservoir Age Program developed by Richard Fairbanks, Naomi Naik and Li Cao at the Lamont Doherty Earth Observatory for use with the Fairbanks Radiocarbon Calibration Program.Win Cal25 is a Windows remake of the CAL25 DOS program. Users can view and make maps and compute estimates for the Marine Radiocarbon Reservoir Age of the surface ocean based on model and measured radiocarbon reservoir age estimates.Comparisons can also be made to any user-supplied data-set.
The package also allows Bayesian analysis of sequences, phases, tree-ring sequences, age-depth models, etc. BCal: Online Bayesian radiocarbon calibration tool. Developed at the Department of Probability & Statistics, University of Sheffield (UK), this allows users to obtain calibrated dates on data sets entered via a Web browser.
It has the same functionality as CAL25 but with a new user interface.. As described in: "Marine Radiocarbon Calibration Curve Spanning 0 to 50,000 Years B. Based on Paired 230Th/234U/238U and 14C Dates on Pristine Corals," by Richard G. Mortlock, Tzu-Chien Chiu, Li Cao, Alexey Kaplan, Thomas P. The program operates on the Google Earth and Google Map application engines and features overlay data sets particularly useful for interpreting the radiocarbon reservoir age estimates.
