Abstract:
(EN) In order to prepare a useful radioactive substance from radioactive nuclides included in high-level radioactive waste and the like, an embodiment of the present invention provides a method for preparing a radioactive substance including a muon irradiation step for obtaining a first radioactive nuclide by causing negative muons to be incident onto a radioactive target nuclide and triggering a nuclear muon capture reaction. The prepared radioactive substance includes at least one of the first radioactive nuclide and a second radioactive nuclide that is at least one type of a descendant nuclide obtained from the first radioactive nuclide through radioactive decay. An embodiment of the present invention also provides the radioactive substance.
(FR) Afin de préparer une substance radioactive utile à partir de radionucléides compris dans des déchets radioactifs de haut niveau et analogues, un mode de réalisation de la présente invention concerne un procédé de préparation d'une substance radioactive, comprenant une étape d'irradiation par muons pour obtenir un premier radionucléide en amenant des muons négatifs à être incidents sur un nucléide cible qui est le radionucléide et en déclenchant une réaction de capture de noyau atomique de muons. La substance radioactive préparée comprend au moins l'un du premier radionucléide et d'un second radionucléide qui est au moins un type quelconque d'un nucléide descendant obtenu par décroissance radioactive à partir du premier radionucléide. Le mode de réalisation de la présente invention concerne également la substance radioactive.
(JA) 高レベル放射性廃棄物などに含まれる放射性核種から有用な放射性物質を製造するために、本発明の実施形態においては、放射性核種である標的核種に負ミュオンを入射させてミュオン原子核捕獲反応を引き起こすことにより第1放射性核種を得るミュオン照射工程を含む放射性物質の製造方法が提供され、製造される放射性物質は、第1放射性核種、および第1放射性核種から放射性崩壊を経て得られる子孫核種の少なくとも1種である第2放射性核種、のうちの少なくともいずれかを含んでいる。また、本発明の実施形態においては当該放射性物質も提供される。
