What is the meaning of radioactive carbon dating
One of the interesting applications of radioactive decay is the technique of radioactive dating.Radioactive dating allows the estimation of the age of any object which was alive once, using the natural radioactivity of .Rachel Wood does not work for, consult, own shares in or receive funding from any company or organisation that would benefit from this article, and has disclosed no relevant affiliations beyond the academic appointment above.
Obviously, this works only for things which were once living.
"Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.
We know that it is older than Christendom, but whether by a couple of years or a couple of centuries, or even by more than a millenium, we can do no more than guess." [Rasmus Nyerup, (Danish antiquarian), 1802 (in Trigger, 19)].
Therefore, the half-life of a radioactive element is independent of the amount of sample.
With the help of half-life values of a suitable radioisotope of an element, which is present in a rock, or in an artifact, the age of the rock and the artifact can be determined.
