What is carbon dating mean?

This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature. C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14. C-14 is produced in the upper atmosphere when nitrogen-14 (N-14) is altered through the effects of cosmic radiation bombardment (a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope). The new isotope is called


Is carbon dating wrong?

Carbon dating is only accurate up to about 60 000 years. It makes the assumption that the concentration of C-14 in our atmosphere has been relatively constant for the last 60 000 years. If this assumption is correct then carbon dating is accurate. It cannot be used for samples less than around 100 years due to the testing of atomic bombs which altered the 14C levels. Calibration curves are used to date the age of know antiquities (they are mentioned in historical documents so their age can be known). Other than that there are inaccuracies of a few percent as the object gets older than several thousand years.

How far back can carbon dating be used?

As far back as there were organisms who were able to consume food containing both ordinary carbon and an isotope of carbon; the comparison of the ratios - which pinpoints the time when an organism stopped eating - gives rise to carbon dating.

How far back can artifacts date back to?

Artifacts can date back thousands to millions of years, depending on the material and preservation conditions. The oldest known artifacts, such as stone tools and cave paintings, date back to millions of years ago.


What is the accuracy of dating a 500 year old seed and a 1000000 year old bone with carbon 14 dating?

Only the seed could be effectively dated using C14. The bone, at one million years old, is far outside the range for which carbon dating is effective. Once the Carbon 14 within a sample has decayed significantly it becomes impossible to measure the remaining amount and establish an age. Currently, using modern methods we can date items using carbon dating up to around 60,000 years before present. The seed, superficially would be a good candidate for carbon dating, however because of it's age and the process of calibrating radiocarbon dates into calender years there would be quite a large range of dates. If you were to test the seed (assuming is was 500years old) a calibrated age would likely be something like 590-400 years before present with a 95% chance of the age falling within that range, or 430-550 years before present with a 68% chance of the age falling within that range. It is impossible to give a perfect answer to this question without actually having a sample and testing it. Quite often it is possible to be more specific than this, and you typically find dates given within a few decades, although there are variations. When results from a sample come back from a laboratory you may be given several date ranges, each with an associated probability. It is up to the researcher which they feel is accurate enough to include in publication or interpretation.
