Once an organism is decoupled from these cycles (i.e., death), then the carbon-14 decays until essentially gone.

The half-life of a radioactive isotope (usually denoted by \(t_\)) is a more familiar concept than \(k\) for radioactivity, so although Equation \(\ref\) is expressed in terms of \(k\), it is more usual to quote the value of \(t_\).

The accuracy of this proposal was proven by dating a piece of wood from an Ancient Egyptian barge, of whose age was already known.They found a form, isotope, of Carbon that contained 8 neutrons and 6 protons.Using this finding Willard Libby and his team at the University of Chicago proposed that Carbon-14 was unstable and underwent a total of 14 disintegrations per minute per gram.The entire process of Radiocarbon dating depends on the decay of carbon-14.This process begins when an organism is no longer able to exchange Carbon with their environment.
