  • Method for producing Ac-225 by irradiation of Ra-226 with protons
    Patent number: 6299666
    Abstract: 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 9 14 and 17 MeV. By this means the yield of production of the desired isotope Ac-225 is enhanced with respect to other radioisotopes.
