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.After the organism dies it stops taking in new carbon.

Age determinations can also be obtained from carbonate deposits such as calcite, dissolved carbon dioxide, and carbonates in ocean, lake, and groundwater sources.
Cosmic rays enter the earth's atmosphere in large numbers every day and when one collides with an atom in the atmosphere, it can create a secondary cosmic ray in the form of an energetic neutron.
With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.
Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.
The number of neutrons in the nucleus can vary in any given type of atom.
So, a carbon atom might have six neutrons, or seven, or possibly eight—but it would always have six protons.
Libby and coworkers, and it has provided a way to determine the ages of different materials in archeology, geology, geophysics, and other branches of science.
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.
Radiocarbon dating is a method of estimating the age of organic material.
It was developed right after World War II by Willard F.
By measuring the ratio of carbon-12 to carbon-14 in the sample and comparing it to the ratio in a living organism, it is possible to determine the age of the artifact.
