METHOD FOR PREPARING AT LEAST ONE GENERATOR WITH A HIGH RADIUM-228 CONTENT
The invention relates to a method for preparing one or more generators with a high radium-228 content from an aqueous solution comprising thorium-232 and radium-228.

The method and the generator(s) that it can be used to prepare are therefore applicable, in particular, in the manufacture of radiopharmaceuticals made from lead-212 or bismuth-212, which can be used in nuclear medicine and, in particular, in targeted alpha radiotherapy for the treatment of cancers.
The invention relates to a method for transferring a radioisotope that is attached to a first stationary phase contained in a first chromatography column to a second stationary phase contained in a second chromatography column, in order to fix the radioisotope to the second stationary phase, wherein the radioisotope is selected from the radioactive isotopes of thorium, radium, lead, bismuth and uranium. Said method comprises at least the following steps: a) eluting the radioisotope from the first stationary phase with an aqueous solution A1 comprising an agent complexing the radioisotope, whereby an aqueous solution A2 is obtained which comprises complexes of the radioisotope; b) dissociating the complexes of the radioisotope present in the aqueous solution A2 by modifying the pH of the aqueous solution A2, whereby an aqueous solution A3 comprising the decomplexed radioisotope is obtained; c) loading the second stationary phase with the aqueous solution A3; and d) carrying out at least one washing of the second stationary phase with an aqueous solution A4.
