Transmutation(redirected from transmutational)
Also found in: Dictionary, Thesaurus, Medical, Legal.
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. It is used mainly in radiobiology, since the transmutation effect exhibited by radionuclides incorporated into the tissues of an organism can be an important factor in the substances’ biological activity. In genetics, transmutation sometimes refers to all gene mutations or those mutations that are induced by a radionuclide that has been absorbed by tissues.
