Radiochemical studies relevant to 86Y production via 86Sr(p,n)86Y for PET imaging

A novel production technique of yttrium-86 based on bombardment of deposited strontium carbonate was investigated. 86Y was produced via proton-induced reactions on SrCO3 target that was prepared by the sedimentation method. Production yield of 0.37 mCi/μAh at 30 μA was measured by means of γ-ray spectrometry for natural target. The separation of 86/87/88Y from Cu and Sr was carried out by two ion-exchange columns.
