Radiometric dating or radioactive dating is any technique used to date organic and also inorganic materials from a process involving radioactive decay. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. The radioactive decay law states that the probability per unit time that a nucleus will decay is a constant, independent of time. This constant probability may vary greatly between different types of nuclei, leading to the many different observed decay rates. The radioactive decay of certain number of atoms mass is exponential in time.

Its presence can be explained by the following simple observation.
