WebRadioactive half-life is the time required for a quantity of a radioisotope to decay by half. If the half-life of an isotope is relatively short, e.g. a few hours, most of the radioactivity will be gone in a few days. If the half-life of an isotope is relatively long, e.g. 80 years, it will take a long time for significant decay to occur.
