FIELD: power engineering.
SUBSTANCE: method to produce a radionuclide bismuth-212 from a nitrate solution containing a mixture of radionuclides thorium-228, thorium-229 and their daughter products of decay, and release of the finished product at an ion-exchange column with cationite. The nitrate solution contains a mixture of radionuclides thorium-228 and thorium-229 and their daughter products of decay, is mixed with ethyl alcohol, this mixture is eluted via the ion exchange column with cationite, where all cations contained in the mixture are absorbed, and as bismuth-212 is accumulated, bismuth-212 is washed by diluted hydrochloric acid.
EFFECT: simplified technological process of production of a radionuclide bismuth-212.
