Age of Minerals and Rocks Formula

How to Determine the Age using Radioactive isotopes?

Each radioactive isotope decays with a characteristic rate which is invariable under all conditions of temperature, pressure and chemical environment. However, radioactivity being a statistical phenomenon, the invariability of the decay constant is assured only as long as large number of atoms are present; with this provision, radioisotopes can be looked upon as nature's atomic clocks recording the passage of time since the birth of the universe in terms of number of atoms decayed.
The basis of age determination by radioactive method depends on the the sample containing a radioisotope in equilibrium with it's stable product and of an age commensurate with the half-life.
