It also has some applications in geology; its importance in dating organic materials cannot be underestimated enough.In 1979, Desmond Clark said of the method “we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation” (3).The ratio of radiocarbon to stable carbon atoms in the atmosphere has varied in the past.This is because the amount and strength of cosmic radiation entering the earth's atmosphere has varied over time.Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.

The atmosphere contains many stable carbon atoms and relatively few radiocarbon atoms.History, anthropology, and archaeology are three distinct but closely related bodies of knowledge that tell man of his present by virtue of his past.Historians can tell what cultures thrived in different regions and when they disintegrated.The other two isotopes in comparison are more common than carbon-14 in the atmosphere but increase with the burning of fossil fuels making them less reliable for study (2); carbon-14 also increases, but its relative rarity means its increase is negligible. After this point, other Absolute Dating methods may be used.Today, the radiocarbon-14 dating method is used extensively in environmental sciences and in human sciences such as archaeology and anthropology.
