Patent ID: 7781744

Claim:
A procedure for the preparation of radioisotopes comprising a first step of electrodepositing a metallic isotope target to be irradiated on a target-holder element, a second step of irradiating said target, a third step of dissolving said target and a fourth step of purifying the radioisotope from the initial metallic isotope and from other possible radioactive and metallic impurities; said procedure being characterised in that said electrodeposition step comprises a dissolution operation in which the isotope to be irradiated is dissolved in a solution of HNO 3 with concentration from 0.5 to 2.5 M, a pH buffering operation, and a recirculation operation, in which the solution obtained above is circulated at a rate of 0.5 to 3 ml/min within an electrolytic cell during the output of current within the cell itself; said isotope target to be irradiated being produced by electrodeposition in said electrolytic cell during said recirculation operation.
