Nuclear decay has a constant rate of decay, but as it turns out, the formation of C has been reliably calibrated to tens of thousands of years.The newest limit using cross-checking methods is around 26,000 years (Dotinga 2005).Samples significantly older than this have very little or even no measurable C left.In order to function properly, natural clocks need an irreversible process that occurs at a constant and known rate.The RATE team (Radioisotopes and the Age of the Earth) have studied a variety of subjects pertaining to the age of the Earth including radiocarbon dating.In the traditional model of science, radiocarbon has little to do with the age of the Earth, since its lifespan is so short.This paper will focus on how the radiocarbon dating method works, how it is used by scientists, and how creationists have interpreted the results.Carbon-14 is a radioactive isotope formed in the upper atmosphere.

Theoretically, radiocarbon techniques have the ability to date samples to around 75,000 years, but the working threshold of reliable dating is around 50,000 years.A small portion of the sample is put into the machine which then vaporizes it.Taking advantage of the distinct mass of individual isotopes, the machine distinguishes the C from all of the other atoms and molecules present and is able to count the individual atoms.It is constantly being produced by a system in which cosmic rays from the sun hit atoms, releasing neutrons. Carbon-14 becomes a part of the mostly homogenous mixture of air in the atmosphere.It can combine with other atoms and molecules such as oxygen to create carbon dioxide, or CO2.
