Related to radiocarbon dating: Potassium argon dating. A form of radiometric dating used to determine the age of organic remains in ancient objects, such as archaeological specimens, on the basis of the half-life of carbon and a comparison between the ratio of carbon to carbon in a sample of the remains to the known ratio in living organisms. Also called carbon dating , carbon dating. All rights reserved. The 14 C decays to the nitrogen isotope 14 N with a half-life of years. Measurement of the amount of radioactive carbon remaining in the material thus gives an estimate of its age. Also called: carbon dating.

Radiocarbon dating has transformed our understanding of the past 50, years. Professor Willard Libby produced the first radiocarbon dates in and was later awarded the Nobel Prize for his efforts.
This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature. C is by far the most common isotope, while only about one in a trillion carbon atoms is C C is produced in the upper atmosphere when nitrogen N is altered through the effects of cosmic radiation bombardment a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope. The new isotope is called "radiocarbon" because it is radioactive, though it is not dangerous. It is naturally unstable and so it will spontaneously decay back into N after a period of time.
