British Broadcasting Corporation Home. The amount of carbon in the atmosphere has not changed in thousands of years. Even though it decays into nitrogen, new carbon is always being formed when cosmic rays hit atoms high in the atmosphere. Plants absorb carbon dioxide from the atmosphere and animals eat plants.

This means all living things have radioactive carbon in them. When an organism, eg a tree, dies it stops taking in carbon dioxide. The amount of carbon in the wood decreases with time as it decays into nitrogen with a half-life of about years. By comparing how much carbon radiocarbon dating half life is in the dead organism with the amount in a living one, the age of the dead organism can be estimated.

The half-life of uranium is million years. When it decays it forms thorium which is also unstable. Finally, after a series of radioactive isotopes are formed it becomes lead, which is stable. The age of the rock can be calculated if the ratio of uranium to lead is known. As the rock gets older the proportion of lead increases. If half of the uranium has turned into lead the rock will be million years old.
