Abstract—

The cumulative yield of the 103Ru radioisotope was measured using the activation method when a 100MoO3 target was irradiated by 4He nuclei with an energy of 60.3 MeV at the U-150 cyclotron of the Kurchatov Institute National Research Center. The measured 103Ru yield was (4.93 ± 0.84) × 104 Bq/(µA h). An experimental technique has been developed for prompt gas thermal separation of 103Ru radioisotope from an irradiated target. An experimental setup has been created to implement the 103Ru extraction technique. The design of the setup and the principle of its operation are presented. It is shown that the technique ensures the extraction of at least 97% 103Ru from the target material and the return of at least 96% 100MoO3 for reuse. The developed technique can find practical application in the production of the 103Ru radioisotope by irradiating of 100MoO3 cyclotron targets with 4He nuclei.
