Through photosynthesis carbon dioxide enters plants and algae, bringing radiocarbon into the food chain.

There are also significant plateaus in the curves, such as the one from 11, to 10, radiocarbon years BP, which is believed to be associated with changing ocean circulation during the Younger Dryas period.

Carbon has two stable, nonradioactive isotopes: This, in turn, would allow us to develop a proper interpretation of all carbon dates. With time, those sand grains fell to the bottom bowl, so the new number represents the carbon atoms left in the mammoth skull when we found it.

After each half-life of 5, years, the number of parent radiocarbon atoms remaining is halved.

The packaging should also be airtight to avoid contact with atmospheric C Radiocarbon ages are still calculated using this half-life, and are known as "Conventional Radiocarbon Age".
