The amount of carbon-14 in the air has stayed the same for thousands of years.

There is a small amount of radioactive carbon-14 in all living organisms because it enters the food chain.

Materials that originally came from living things, such as wood and natural fibres, can be dated by measuring the amount of carbon-14 they contain.

For example, in 1991, two hikers discovered a mummified man, preserved for centuries in the ice on an alpine mountain.

There are two techniques for dating in archaeological sites: relative and absolute dating.
