The half-life of carbon-14 is about 5730 years. (That's 5,730 ±40 years, if more accuracy is desired.) A link can be found below for more information about radiocarbon, which is what we commonly call carbon-14.

∙ 13y agoThe half life of Carbon 14 is 5730 years. This is a very useful isotope for measuring archaeological material, and with a good sample, one may date a sample to about ten half lives - about 57300 years. For longer periods, other isotopes are used.
The uncertainty of the measurement increases with the total time.
C14 is not useful for recent dating because of the quantity of material released during atomic bomb testing.

What is the half life of carbon -14?
The half-life of carbon 14 is 5,730 years.
What is a Libby half-life?
A Libby half-life is another name for the half-life of carbon-14, used in carbon dating, which was a process invented by Willard Libby and his colleagues. The numerical value of a Libby half-life is 5568±30 years.
What is the radioactive form of carbon?
There are several radioactive forms of carbon. The most familiar, used in carbon dating, is carbon-14. All of the others have very short half-lives.Isotopes of carbon range from carbon-8 to carbon-22. Carbon-12 and carbon-13 are stable and non-radioactive. Carbon-14 has a half-life of 5730 years. The longest lived beyond that is carbon-11 at 20.3 minutes.
What is the length of decay of carbon-14?
The half life of Carbon 14 is about 5730 years.
The half life of carbon 14 is 5730 years If a 1g sample of old carbon is one eighth as radioactive as 1g of a current sample then the age is about?
17,200 Years
What is the half life of carbon -14?
The half-life of carbon 14 is 5,730 years.
What is the half- life of radioactive carbon?
Carbon-14 or 14C, which is a radioactive isotope of carbon, has a half life of 5,700 years.
How do you find the half life in carbon dating?
You do not find the half life in carbon dating. The half lives of carbon isotopes are derived by studying their radioactive decay. For carbon dating, the isotope used is Carbon-14, which has a half life of 5,700 years.
When A carbon-14 sample starts with 100 atoms and 5730 years later there are 50 atoms. What is the half-life of carbon-14?
The half-life of carbon-14 is 5 730 years.
How is half life used for carbon dating?
Knowing the half life of carbon-14 the age of an artefact containing an organic material can be evaluated.
The half-life of carbon-14 is approximately what?
5,730 years.
What is the half life of carbon-14 and what does this refer to?
The half-life of carbon-14 is about 5700 years. Some sources say 5730, but I don't know the accuracy of that number. In the case of carbon-14, this is the period of time for half the original material to decay to nitrogen-14. This is useful in carbon dating, where the ratio of carbon-14 to carbon-12 and carbon-13 is measured, giving an estimate for the age of a carboniferous (plant material) sample.
The process that uses half life in its computation?
The process that uses half life in its computation is carbon-14 dating. Carbon-14 dating of a former living thing determines the age at death.
What is a Libby half-life?
A Libby half-life is another name for the half-life of carbon-14, used in carbon dating, which was a process invented by Willard Libby and his colleagues. The numerical value of a Libby half-life is 5568±30 years.
The carbon-14 in a wooden sample shows a ratio of 0.280 between the carbon-14 in the wood and present-day samples The half-life of carbon-14 is 5730 years How old is the wood?
10,500 years old The carbon-14 in a wooden sample shows a ratio of 0.0093 between the carbon-14 in the wood and present-day samples. The half-life of carbon-14 is 5,730 years. How old is the wood? 38,700 years old

How do scientists use Carbon-14 to date fossils?
Carbon-14 is in all living things and decays after it dies. It has a long half life (the time it takes for half a sample to decay into another element) and gives a good estimate as to how old something is. Carbon dating is only effective up to an approximate age of 70,000 years, and is only useful in dating organic matter. Since the vast majority of fossils are much older than this, carbon dating is not particularly useful in dating fossils, but is of great use in archaeology.
