Denoting a material produced by radioactive decay, e.g. the lead formed from uranium. Radiogenic dating is a technique for calculating the age of an object by determining the ratio of the concentration of a particular radioisotope in the object to the concentration of its stable isotope. For example, in archaeology the age of objects, such as bones, can be estimated by finding the ratio of carbon–14 to carbon–12.
