other isotope pairs cover intermediate time periods between the spans for carbon 14 and uranium.Some radiometric dating methods depend upon knowing the initial amount of the isotope subject to decay.Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.This rules out carbon dating for most aquatic organisms, because they often obtain at least some of their carbon from dissolved carbonate rock.The concept behind radiocarbon dating is rather simple.While organisms live, they incorporate radioactive carbon-14 from the atmosphere.

When Libby developed the radiocarbon dating technique, he validated the method by comparing measured carbon ratios (carbon-14/carbon-12) from artifacts of known age with predictions of the ratio expected by assuming the decay rate.Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.
