This method, which received widespread attention in connection with the Dead Sea Scrolls, relies on the fact that all living things take in carbon, some of which is very slightly radioactive. To hear some people tell it, scientists have nearly absolute confidence in the dating methods they use.

Later called Ötzi the Iceman, small samples from his body were carbon dated by scientists.

The results showed that Ötzi died over 5000 years ago, sometime between 33 BC. It is found in the air in carbon dioxide molecules.

Plants obtain all their carbon atoms from the atmosphere.

Anything that was once alive or that was produced by a living thing can be dated by using the radiocarbon method of dating.

For example, Christian time counts the birth of Christ as the beginning, AD 1 (Anno Domini); everything that occurred before Christ is counted backwards from AD as BC (Before Christ).

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

This is because the amount and strength of cosmic radiation entering the earth's atmosphere has varied over time.

(This, in turn, is caused by variations in the magnetic fields of the earth and sun, for example.) Although the ratio of radiocarbon to stable carbon in the atmosphere has varied over time, it is quite uniform around the globe at any given time because the atmosphere mixes very quickly and constantly.

The approximate time since the organism died can be worked out by measuring the amount of carbon-14 left in its remains compared to the amount in living organisms.
