DOC Half-Life Radioactive Isotopes 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.

RadTown Radioactive Atom Activity 5: Half-Life | US EPA When a radioactive atom decays, it becomes a different element. The amount of time that it takes one half of the atoms present to decay is called "half-life." Every radioactive isotope has a specific half-life. Help your students understand this concept using interactive classroom activities.
