The occurrence of natural radioactive carbon in the atmosphere provides a unique opportunity to date organic materials as old as roughly 60,000 years.Unlike most isotopic dating methods, the conventional carbon-14 dating technique is not based on counting daughter isotopes.

A final problem of importance in carbon-14 dating is the matter of sample contamination.It is clear that carbon-14 dates lack the accuracy that traditional historians would like to have.There may come a time when all radiocarbon ages rest on firmer knowledge of the sample’s original carbon-14 level than is now available.Fortunately, neither effect has been significant in the case of older samples submitted for carbon-14 dating.The ultimate cause of carbon-14 variations with time is generally attributed to temporal fluctuations in the cosmic rays that bombard the upper atmosphere and create terrestrial carbon-14.
