Notify me of new posts via email. The rate of decay of a radioactive isotope is usually given by its half-life. The process starts with examination of the growth ring patterns of samples from living trees. In daughter deficiency situations, the parent radioisotope is initially deposited by itself, without its daughter the isotope into which it decays present.
