DEFINITION

Classification: 376/156

NUCLEAR TRANSMUTATION (E.G., BY MEANS OF PARTICLE OR WAVE ENERGY):

(under the class definition) Subject matter comprising the bombardment of a material to produce an induced nuclear reaction other than that resulting in the splitting of a nucleus.

(1) Note. The subject matter of this class includes reactions wherein a nucleus of the material is converted or transformed into a different nucleus; inclusive of (a) making the material radioactive, (b) producing isotopes of the same

or a different element, e.g., Co[supscrpt]59[end supscrpt] Co[supscrpt]60[end supscrpt], Th[supscrpt]232[end supscrpt] U[supscrpt]233[end supscrpt], and (b) producing annihilation radiation, e.g., a matter antimatter reaction.

(2) Note. Where a substance such as U[supscrpt]238[end supscrpt] (or other material) is merely used as a fuel carrier with no stated intention of converting it to fuel, the substance U[supscrpt]238[end supscrpt] is not regarded as fertile material for this and indented subclasses.
