The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.

Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.

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.

Cal Pal: Cologne Radiocarbon CALibration and PALaeoclimate Package.

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.It is one of several similarly formed cosmogenic nuclides.Newly formed carbon-14 atoms oxidize to carbon dioxide and become thoroughly mixed with the other atmospheric gases, through atmospheric dynamics.Designed for research on glacial C-14 age conversion (PC-WIN). Win Cal25: The Groningen Calibration Program: By J.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.
