摘要: A novel anion-exchange chromatographic method for separation of radioiodine from an antimony target irradiated with 3He- or α-particles was developed, yield amounting to 90 ± 5 % and its decontamination factor the Te Sb radionuclides ~104. The optimized developed then applied production 124I via 121Sb(α,n)124I process using a highly enriched 121Sb target. Quality control tests showed that separated occurred >99 as iodide longer lived impurities 126I 125I amounted 0.16 <0.05 %, respectively. trace level inactive impurity determined by ICP–OES.
