This invention refers to a method for producing Actinium-225, comprising the steps of preparing a target (1) containing Radium-226, of irradiating this target with protons in a cyclotron and of chemically separating Actinium from the irradiated target material thereafter. According to the invention the proton energy in the cyclotron is adjusted such that the energy incident on the Ra-226 is between 10 and 20 MeV, preferably between 14 and 17 MeV. By this means the yield of production of the desired isotope Ac- 225 is enhanced with respect to other radioisotopes.
Cette invention a trait à un procédé de production d'actinium-225 consistant à préparer une cible contenant du radium-226, à irradier cette cible au moyen de protons dans un cyclotron et à séparer par voie chimique l'actinium du matériau constituant la cible irradiée. On adapte, dans le cadre de cette invention, l'énergie des protons dans le cyclotron, de manière que l'énergie incidente au Ra-226 soit comprise entre 10 et 20 MeV, de préférence entre 14 et 17 MeV. On arrive, de ce fait, à accroître la production de l'isotope désiré, Ac-225, en comparaison de celle des autres radio-isotopes.
