Use of radioactive isotopes in carbon dating
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.
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 .
Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.
