Process of carbon dating

These excited neutrons then collide with nitrogen atoms in the atmosphere, changing them into radioactive carbon-14 atoms.

This means that things like stone, metal and pottery cannot usually be directly dated by this means unless there is some organic material embedded or left as a residue.

The Greeks consider the first Olympic Games as the beginning or 776 BC.

The Muslims count the Prophet’s departure from Mecca, or the Hegira, as their beginning at AD 662.

However, once the organism dies, the amount of carbon-14 steadily decreases.

By measuring the amount of carbon-14 left in the organism, it's possible to work out how old it is.
