This is carbon 14 -(14C).
see wikipedia-" http://en.wikipedia.org/wiki/Radiocarbon_dating" if you need an explanation as to how the measurements are made and how the age of a sample is calculated.

Which isotope is found in living things or radiocarbon dating?
This is the isotope carbon-14.
What is the isotope of carbon that is used for dating things in archaeology?
carbon 14
What is the source of the carbon that is used in radiocarbon dating in living things?
The radioactive isotope carbon-14 is natural.
Can carbon dating be used on a stone to determine it's age?
It is not possible to carbon date rocks. Carbon 14 dating is based on the absorption of atmospheric carbon by livingthings. When the thing dies it no longer takes in carbon from the atmosphere through processes such as eating or respiration and levels of C14 in the body deplete due to the natural process of radioactive decay. By seeing how much C14 remains it is possible to see how long it has been since that animal died.However there are a range of other dating methods which can be used.
Which isotope is used to date ancient artifacts such as fossils?
The main isotope used for determining the age of artifacts in archaeology is carbon 14, however there are many others.Other radiometric methods (methods based on the decay rates of radioactive isotopes) include:Potassium-Argon dating - Based on the decay of potassium 40Uranium Series dating - Based on the decay of several isotopes, including Uranium 238 (also used in fission track dating), Uranium 235, Thorium 230 and Protactinium 231.Lead 210 dating - Based (unsuprisingly) on the decay of Lead 210.A climate based method, based on the "Oxygen Isotope timescale" can be used to broadly date things and uses ratios of Oxygen 18 to Oxygen 16.
The isotope of carbon that is used for dating things in archeology?
carbon-14
What is the isotope of carbon that is used for dating things in archeology?
Carbon 14
Which isotope is found in living things or radiocarbon dating?
This is the isotope carbon-14.
What is the isotope of carbon that is used for dating things in archaeology?
carbon 14
What is carbon 13?
Carbon 12 is the most common isotope of carbon. 99.8% of all natural carbon in the universe as we know it is carbon-12
Are there any limits to carbon dating?
Yes:it cannot date things older than ~40,000 years as the carbon-14 isotope has decayed to practically undetectable levels after that much timeas levels of the carbon-14 isotope in the atmosphere vary slightly over time (it is produced by the flux of cosmic rays hitting earth, which varies as the solar system orbits the galaxy, etc.) the dating method must be recalibrated using tree ring count reference samples to keep it accurate over long periods of timeof course it can only be used to date things that were once living, and thus in equilibrium with atmospheric carbon isotope ratios at the time of deathoceanic carbon isotope ratios are different from atmospheric carbon isotope ratios, so this must be accounted for in dating sea creature fossils
What is the source of the carbon that is used in radiocarbon dating in living things?
The radioactive isotope carbon-14 is natural.
Which isotope is found in all living things?
Carbon 14 is one.
What is the isotope found in all living things?
Carbon 14 is one.
Why carbon dating works?
It works, among other things, because:* Like any radioactive isotope, C-14 (the radioactive carbon used for this) decays at a constant (and known) rate. * C-14 is replenished in the atmosphere. * Carbon is absorbed by living beings; and when these die, no more carbon is ingested by them.
What dating process works only on once living things?
carbon dating
