Radioactive Decay

Unlike long-term radiometric dating methods, radiocarbon relies on knowing the fraction of radioactive carbon in the atmosphere at the time the object being dated was alive. The production of carbon by cosmic rays was up to a factor of about two higher than at present in the timescales over which radiocarbon can be used.

radioactive dating A process for determining the age of an object by measuring the amount of a given radioactive material it contains. If one knows how much of this radioactive material was present initially in the object (by determining how much of the material has decayed), and one knows the half-life of the material, one can deduce the age of the object.
