These are released as radioactive particles (there are many types).

By measuring the amount of carbon-14 left in dead organic material the approximate time since it died can be worked out.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 atoms of each element may vary slightly in the numbers of neutrons within their nuclei.As a member, you'll also get unlimited access to over 55,000 lessons in math, English, science, history, and more.
