radiometric dating [‚rād·ē·ə‚me·trik ′dād·iŋ] (archeology) A dating method that utilizes the radioactive decay of certain long-lived, naturally occurring parent isotopes to stable daughter isotopes. (nucleonics) A technique for measuring the age of an object or sample of material by determining the ratio of the concentration of a radioisotope to that of a stable isotope in it; for example, the ratio of carbon-14 to carbon-12 reveals the approximate age of bones, pieces of wood, and other archeological specimens. Also known as isotopic age determination; nuclear age determination; radioactive age determination; radioactive dating; radiogenic age determination; radiogenic dating.
