Haybittle等人於1964年提出 採用的β-射源為24Ci的90Sr,排列成長60cm的直線。因為90Sr-90Y行程永久性放射性平衡,90Y的最大β-能量為2.28MeV,所以其有效治療深度約為數114 mm。  90Y solution by wet ashing, and 90Y is then recovered in a small volumeof 0.02–0.05 mol/L HCl. The method was tested for 100 mCi of 90Sr solution at90Y in-growth times of 1 day, 1 week and 1 month  A  Dowex 50WX8 resin (50–100 mesh)in Na+ form was stirred for several hours in a 90Sr/90Y EDTA solution (pH4–5),and then poured onto a glass column and thoroughly washed with 100 mL of 6mmol/L EDTA solution. I  The 90Sr/90Y EDTA solutions (pH4.5) were passed through a columncontaining Dowex 50WX8 (50–100 mesh) in sodium form at different flow rates(0.1–3 mL/min). The 90Y recovery and the decontamination factor for 90Sr weredetermined.  文字出處: https://www-pub.iaea.org/MTCD/Publications/PDF/trs470_web.pdf

(D) 應該改為 以0.03M EDTA (ethylene diamine tetraacetic acid) 流洗出90Y核醫藥品學 第七版p.97 (其他選項在同一頁中也都有提到)
