METHOD FOR PRODUCING ACTINIUM-225 AND BISMUTH-213

摘要

The invention relates to a method for producing actinium-225 and bismuth-213. according to the invention, radium-226 is irradiated in the thermal neutron flux of a nuclear reactor, the thorium fraction of the irradiation product is then chemically isolated and therefrom the actinium and radium mixture growing continuously by decay therein is chemically separated, this mixture serving as "cow" for the desired radionuclides which are growing continuously.
