= Decay correction
{wiki=Decay_correction}
Decay correction is a process used primarily in the fields of physics and medicine, particularly in radioactivity and nuclear medicine, to adjust measurements of radioactive isotopes to account for the decay of those isotopes over time. This is important for obtaining accurate quantitative results when measuring radioactivity or the concentration of radiopharmaceuticals. When a radioactive material decays, its activity decreases over time according to its half-life, which is the time taken for half of the radioactive atoms in a sample to decay.
