The method was developed immediately following World War II by Willard F.Libby and coworkers and has provided age determinations in archeology, geology, geophysics, and other branches of science.Other corrections must be made to account for the proportion of throughout the biosphere (reservoir effects).Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.Libby theorised that the amount of both non-radioactive and radioactive isotopes of carbon in an organism remain a constant throughout its life, and after this life ends, the absorption stops and carbon-14 starts to decay.The reason why radiocarbon dating is only good for specimens younger than 60,000 years old is that the traces of the isotope are too tiny to detect in older organic matter.Radiocarbon dating, which was discovered for science as a method of dating ancient specimens of organic matter by US chemist Willard Libby, consists in measuring the levels of carbon-14, a radioactive isotope of the element that has a halflife of 5,700 years.All organic matter, while it lives, absorbs this isotope from its environment.

The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.
