C-14 Decay 14c dating range The C-14 within an organism is continually decaying into stable carbon isotopes, but since the organism is absorbing more C-14 during its life, the ratio of 14c dating range to C-12 remains about the same as the ratio in the atmosphere. When the organism dies, the ratio of C-14 within its carcass begins to gradually datibg. That is the half-life of C-14. The animation provides an example of how this logarithmic decay occurs.

One Scientist May Have an Easy Fix If only there were such an easy fix for climate change Radiocarbon dating has been used to determine of the ages of ancient mummies, in some cases going back more than 9000 years. His technique, known as carbon dating, revolutionized the field of archaeology. Related Content Climate Change Might Break Carbon Dating Now researchers could accurately calculate the age of any object made of organic materials by observing how much of a certain form of carbon remained, and then calculating backwards to determine when the plant or animal that the material came from had died. An isotope is a form of an element with a certain number of neutrons, which are the subatomic particles found in the nucleus of an atom that have no charge. While the number of protons and electrons in an atom determine what element it is, the number of neutrons can vary widely between different atoms of the same element.
How Does Carbon Dating Work Carbon-14 is a weakly radioactive isotope of Carbon; also known as radiocarbon, it is an isotopic chronometer. C-14 dating is only applicable to organic and some inorganic materials not applicable to metals.
