BioMath: Carbon Dating

This figure is directly based on the proportion of radiocarbon found in the sample. It is calculated on the assumption that the atmospheric radiocarbon concentration has always been the same as it was in and that the half-life of radiocarbon is years. To give an example if a sample is found to have a radiocarbon concentration exactly half of that for material which was modern in the radiocarbon measurement would be reported as BP. In order to see what a radiocarbon determination means in terms of a true age we need to know how the atmospheric concentration has changed with time.
