8/29/2023 0 Comments Half life alpha![]() There are two definitions of half-life - but they mean essentially the same thing: This is called the half-life of the radioactive isotope. But it is possible to measure how long it takes for half the nuclei of a piece of radioactive material to decay. It is not possible to predict when an individual atom might decay. As this breakdown occurs, the activity of any radioactive source becomes less. įor example, carbon-14 decays to nitrogen-14 when it emits beta radiation. They breakdown and change into a completely different type of atom. The nuclei of radioactive atoms are unstable.
