By comparing the surviving amount of carbon-14 to the original amount, scientists can calculate how long ago the animal died.Since the atmosphere is composed of about 78% nitrogen,2 a lot of radiocarbon atoms are produced—in total about 16.5 pounds (7.5 kg) per year.Well, if carbon-14 can decay into nitrogen-14 and other stuff, then we can create carbon-14 by combining nitrogen-14 with the proper stuff.In this case, that happens to be a neutron, which allows us to do this: (a.k.a., carbon dioxide) and mixing throughout the atmosphere and oceans, easily making its way into living organisms into a well-understood equilibrium.

Rb)—are not being formed on earth, as far as we know.When animals eat the plants, the carbon-14 enters their bodies.The carbon-14 in their bodies breaks down to nitrogen-14 and escapes at the same rate as new carbon-14 is added. CARBON-14 IS DEPLETED (Figure 1c): When an animal dies the carbon-14 continues to break down to nitrogen-14 and escapes, while no new carbon-14 is added.From diamonds to nanotubes to DNA, carbon is indispensable for constructing practically all of the most intricate structures we know of.Most of the carbon in our world comes from long-dead stars, in the form of Carbon-12: carbon atoms containing six neutrons in their nucleus.Radioactive and non-radioactive carbon dioxide mix throughout the atmosphere, and dissolve into the oceans.
