C Decay Profile The C within an organism is continually decaying into stable carbon isotopes, but since the organism is absorbing more C during its life, the ratio of C to C remains about the same as the ratio in the atmosphere. When the organism dies, the ratio of C within its carcass begins to gradually decrease. That is the half-life of C The animation provides an example of how this logarithmic decay occurs.

Carbon-14 dating

A raw date cannot be used directly as a calendar date, because the level of atmospheric carbon 14 has not been constant during the span of time that can be radiocarbon dated. In addition, there are substantial reservoirs of carbon in organic matter, the ocean, ocean sediments, and sedimentary rock. Finally, although radiocarbon dating is the most common and widely used chronometric technique in archaeology today, it is not unfailing. In general, single dates should not be trusted.
