Ra-226 Ac-225 A METHOD FOR PRODUCING AC-225 FROM RA-226

Provided is a method for producing Ac-225 from Ra-226, wherein the Ra-226 is present as a liquid solution in a recipient, the Ra-226 is submitted to a photo-nuclear process and the Ra-226 (γ, n) is irradiated to produce Ra-225 which then decays into the Ac-225, characterized in that the formed Ac-22...

Beschreibung
Zusammenfassung:	Provided is a method for producing Ac-225 from Ra-226, wherein the Ra-226 is present as a liquid solution in a recipient, the Ra-226 is submitted to a photo-nuclear process and the Ra-226 (γ, n) is irradiated to produce Ra-225 which then decays into the Ac-225, characterized in that the formed Ac-225 is collected by an electrochemical precipitation thereof on a cathode present in the recipient, and the cathode is removed from the recipient after the precipitation occurred and brought into a hot cell environment where the Ac-225 is extracted from the cathode. The present invention can avoid the recycling process of the Ra-226 after the chemical separation of the Ac-225. Ra-226 으로부터 Ac-225 를 생성하는 방법 Ra-226 으로부터 Ac-225 를 생성하는 방법에서, 상기 Ra-226 은 수용체에 액체 용액으로서 존재하고, 상기 Ra-226 은 광핵 프로세스에 제출되며, 상기 Ra-226 (JPEGpat00011.jpg55, n) 는 이후 Ac-225 로 붕괴되는 Ra-225 를 생성하기 위해 조사되며, 형성된 Ac-225 는 상기 수용체에 존재하는 캐소드 상의 전기 화학적 침전에 의해 수집되고, 상기 캐소드는 상기 침전이 발생한 후에 상기 수용체로부터 제거되고 핫셀 환경으로 이동되어 상기 Ac-225 가 상기 캐소드로부터 추출된다.
