Carbon dating on the
The ratio of carbon-12 to carbon-14 is the same in all living things.
However, at the moment of death, the amount of carbon-14 begins to decrease because it is unstable, while the amount of carbon-12 remains constant in the sample.
In the following section we are going to go more in-depth about carbon dating in order to help you get a better understanding of how it works.
Radiocarbon dating is a method of estimating the age of organic material.
For radiocarbon dating to be possible, the material must once have been part of a living organism.
It can be applied to most organic materials and spans dates from a few hundred years ago right back to about 50,000 years ago - about when modern humans were first entering Europe.
Maybe one in a trillion carbon atoms are carbon-14.
Both Carbon-12 and Carbon-13 are stable, but Carbon-14 decays by very weak beta decay to nitrogen-14 with a half-life of approximately 5,730 years.
Some examples of the types of material that radiocarbon can determine the ages of are wood, charcoal, marine and freshwater shell, bone and antler, and peat and organic-bearing sediments.
Age determinations can also be obtained from carbonate deposits such as calcite, dissolved carbon dioxide, and carbonates in ocean, lake, and groundwater sources.
