DOC Half-Life Radioactive Isotopes - teachnlearnchem.com The half-life is a measure of how much time it takes for ½ of a sample of radioactive atoms to decay into stable, or non-radioactive, atoms. After one half-life passes, only ½ of the atoms are still radioactive - the other half are stable. After a second half-life passes, another ½ of the remaining radioactive atoms have decayed into stable nuclei.
