title: Separation of fission produced106Ru from simulated high level nuclear wastes for production of brachytherapy sources.
abstract: An effective and simple process for the isolation of106Ru from high-level liquid wastes was developed. Radioactive ruthenium was oxidized by H5IO6in HNO3solution and was extracted to CCl4phase in the form of RuO4. In order to obtain ruthenium in the suitable form for production of brachytherapy sources, RuO4in organic phase was reduced and re-extracted to aqueous phase. The efficiency of extraction of103Ru to organic phase was 86 %, re-extraction to aqueous solution was near 100 %, so the overall recovery of103Ru is estimated at more than 80 %.
