ra·di·o·ac·tive e·qui·lib·ri·uma situation (not a true equilibrium) in which a particular atom is being produced by the radioactive breakdown of a precursor while it is itself breaking down, the two breakdowns matching so that over a period of time the ratio of radioactivity of product and precursor is constant. |
