For example, techniques based on isotopes with half lives in the thousands of years, such as Carbon-14, cannot be used to date materials that have ages on the order of billions of years, as the detectable amounts of the radioactive atoms and their decayed daughter isotopes will be too small to measure within the uncertainty of the instruments.
It does not, however, allow one to independently assign an accurate estimation of the age of an object as expressed in years.decay or the rate of other cumulative changes in atoms resulting from radioactivity.
