the conversion of atoms of one chemical element into those of another as a result of the radioactive decay of the atomic nuclei. In physics, the term “transmutation” has fallen into disuse.

In genetics, transmutation sometimes refers to all gene mutations or those mutations that are induced by a radionuclide that has been absorbed by tissues.
