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

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

The carbon-14 it contained at the time of death decays over a long period of time, and the radioactivity of the material decreases.

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.

The Carbon-14 within a living organism is continually decaying, but as the organism is continuously absorbing Carbon-14 throughout its life the ratio of Carbon-14 to Carbon-12 atoms in the organism is the same as the ratio in the atmosphere.

Once an organism dies it stops taking in Carbon in any form.

Later called Ötzi the Iceman, small samples from his body were carbon dated by scientists.There's a small amount of radioactive carbon-14 in all living organisms.When they die no new carbon-14 is taken in by the dead organism.The carbon-14 it contained at the time of death decays over a long period of time.

By measuring the amount of carbon-14 left in dead organic material the approximate time since it died can be worked out.We guarantee the authenticity of your paper, whether it's an essay or a dissertation.
