It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.
<h3>How are isotopes used in radioactive dating?</h3>
These isotopes decay within the rocks according to their half-life rates, and by choosing the fit minerals and measuring the relative amounts of parent and daughter isotopes in them, the date at which the rock crystallized can be determined.
Thus, It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope.
