Experimental Investigations for Substantiating the Development of a 103Ru/103mRh Generator

The 103Ru radionuclide has been produced using a reactor and identified with the aim of developing the 103Ru/103mRh generator. Methods for synthesis and distillation of highly volatile RuO4 from metallic ruthenium and from solutions have been developed and tested. The effect of RuO4 purification from concomitant radionuclides during distillation is shown. The feasibility of separating ruthenium and the target radioisotope 103mRh by thermal distillation of RuO4 has been demonstrated for the first time.
