transmutationnounThe process or result of changing from one appearance, state, or phase to another:change, changeover, conversion, metamorphosis, mutation, shift, transfiguration, transformation, translation, transmogrification, transubstantiation.TranslationsTransmutation
transmutation[‚trans·myü′tā·shən] (nuclear physics) A nuclear process in which one nuclide is transformed into the nuclide of a different element. Also known as nuclear transformation. Transmutation 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. transmutation
