Radioactive contaminations in soil, which originate from nuclear power production, nu-clear weapon testing or uncontrolled release, are of great environmental concern. One of the major fission product contaminants is 90Sr, whose high mobility demands a method to track contamination pathways and remediation processes. Positron emission tomography (PET) is a valuable tool for the required studies. As a β-/γ-emitter, 90Sr is not suitable for PET, which requires β+-emitters. As an alternative, 83Sr offers, with a 12% intensity of β+-emission and a half-life of 32.4 h an appropriate PET substitute for 90Sr. We produced 83Sr with an enriched target of [85Rb]RbCl in an 85Rb(p,3n)83Sr reaction. The target material was bombarded with 36.22 MeV protons (ø 2 µA, 315 min), at a solid target station at the cyclotron U-120M (NPI CAS). The irradiated target (1.5 GBq) was dissolved in water, evaporation to dryness, redissolved in nitric acid and transferred onto a Sr-selective car-tridge (Sr-SpecTM, TRISKEM, France). Following target material wash out, 83Sr elution with water, solvent evaporation and reformulation (dilute nitric acid) yielded 1.2 GBq (82% radiochemical extraction efficiency, non-decay corrected) of an 83Sr-solution. The easy and fast method is able to produce non-carrier-added 83Sr with high radionuclidic purity.
