Use of carbon 14 dating

Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon.

At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues.

It is based not on the amount of the Carbon $ isotope remaining in the sample but rather on the ratio of Carbon $ to Carbon $.It takes about 5,730 years for half of a sample of radiocarbon to decay back into nitrogen.It takes another 5,730 for half of the remainder to decay, and then another 5,730 for half of what's left then to decay and so on.In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years.This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago.

When an organism dies it ceases to replenish carbon in its tissues and the decay of carbon 14 to nitrogen 14 changes the ratio of carbon 12 to carbon 14.
