The present invention relates to a radium target as well as to a method for producing it for the production of radionuclides by means of accelerated protons, wherein an electrodeposition of radium out of at least one aqueous organic solution containing 226Ra ions is carried out on at least one aluminium surface, wherein the aluminium surface is connected as cathode. With the226Ra target according to the present invention, 225Ac/213Bi, which can be used, for example, for radioimmunotherapy for cancer treatment, can be produced continuously and in sufficient quantities at a reasonable price. L'invention concerne une cible de radium, ainsi qu'une méthode de production de la cible destinée à la production de radionucléides, au moyen de protons accélérés. Une électrodéposition de radium utilisant au moins une solution organique aqueuse contenant des ions ?226¿Ra est réalisée sur au moins une surface en aluminium raccordée en tant que cathode. La cible ?226¿Ra de l'invention permet de produire en continu et en quantités suffisantes, à un prix raisonnable,? 225¿Ac/?213¿Bi utilisables en radio-immunothérapie, par exemple, pour le traitement du cancer.
