G21G - Definition
This subclass covers:
Arrangements for the conversion of chemical elements, including but not limited to, arrangements using electromagnetic radiation, corpuscular radiation or particle bombardment. Examples include systems for producing radioactive isotopes through neutron bombardment.
Radioactive sources.
Alleged conversion of chemical elements by chemical reaction.
References relevant to classification in this subclass
This subclass does not cover:
Adaptations of reactors to facilitate experimentation or irradiation. Examples of such adaptations include modification of the reactor core to enable exposure of samples for investigative purposes. | G21C 23/00 |
Irradiation devices. These typically include arrangements to deliberately subject bodies or materials to ionising radiation in order to take advantage of known effects of the radiation thereon. | G21K 5/00 |
Applying radioactive material to the body | A61M 36/00 |
Radiation therapy using radioactive sources | A61N 5/10 |
Conversion of chemical elements by thermonuclear reactions in fusion reactors | G21B |
Conversion of nuclear fuel in fission reactors | G21C |
Application of radiation from radioactive sources | G21H 5/00 |
Attention is drawn to the following places, which may be of interest for search:
Preparations containing radioactive substances for use in therapy or testing in vivo | A61K 51/00 |
Separation of different isotopes of the same element | B01D 59/00 |

Producing neutrons or other subatomic particles, X- or gamma rays: | |
in fusion reactors | G21B |
in nuclear reactors | G21C |
by cosmic radiation | G21H 7/00 |
in accelerators | H05H |
