This expression works even if the number of half-lives is not a whole number. Example 11.5.1: Fluorine-20. WebThe nuclei break down as the radioactive isotope changes to a stable non-radioactive isotope over time. The beginning isotope is called the ‘parent’ and the new isotope is called the ‘daughter’. An isotope’s half-life is the time it takes for half of the atoms of the parent isotope to change into atoms of the daughter isotope. cord-blood bank
