Radiation dating definition

Plants absorb carbon dioxide from the atmosphere and animals eat plants.

This means all living things have radioactive carbon-14 in them.

When an organism, eg a tree, dies it stops taking in carbon dioxide.

The amount of carbon-14 in the wood decreases with time as it decays into nitrogen with a half-life of about 5700 years.

Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.
