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.

The different isotopes of carbon do not differ appreciably in their chemical properties.

Anything that dies after the 1940s, when Nuclear bombs, nuclear reactors and open-air nuclear tests started changing things, will be harder to date precisely.

Perhaps no concept in science is as misunderstood as "carbon dating." Almost everyone thinks carbon dating speaks of millions or billions of years.

These are relatively low energies; the maximum distance traveled is estimated to be 22 cm in air and 0.27 mm in body tissue.

The fraction of the radiation transmitted through the dead skin layer is estimated to be 0.11.

There's a small amount of radioactive carbon-14 in all living organisms.
