| description | To provide a method for producing Ac-225 from Ra-226, capable of avoiding a recycling process of the Ra-226 after chemical separation of the Ac-225.SOLUTION: This invention relates to a method for producing Ac-225 from Ra-226 that is present as a liquid solution in a recipient, the Ra-226 being submitted to a photo-nuclear process in which the Ra-226 (γ,n) is irradiated to produce Ra-225 which then decays into the Ac-225, wherein: the formed Ac-225 is collected by an electrochemical precipitation of Ac-225 on a cathode present in the recipient; and the cathode is removed from the recipient after the precipitation occurred and is brought into a hot cell environment where the Ac-225 is extracted from the cathode.SELECTED DRAWING: Figure 2
【課題】Ａｃ−２２５の化学的分離後にＲａ−２２６のリサイクルプロセスを避ける事ができるＲａ−２２６からＡｃ−２２５を製造する方法を提供する。【解決手段】Ｒａ−２２６を、Ｒａ−２２６（γ，ｎ）の照射によりＲａ−２２５が生成された後にＲａ−２２５がＡｃ−２２５へと崩壊する光核過程に供する事で、受容器内に液体溶液として存在するＲａ−２２６からＡｃ−２２５を製造する方法であって、形成されたＡｃ−２２５を、上記受容器内に存在するカソード上でのＡｃ−２２５の電気化学的析出によって収集し、ここで、上記カソードは、上記析出が起こった後に上記受容器から取り出され、上記Ａｃ−２２５が上記カソードから抽出されるホットセル環境へと導入される、方法。【選択図】図２ |
