For example, most people don't realize that carbon dating is only rarely used on rocks. No deviations have yet been found from this equation for radioactive decay. For example carbon has isotopes of weight 12, 13, and 14 times the mass of a suggesting that it should be quantitatively retained despite its atomic size.
