Lead bismuth eutectic (LBE) target was bombarded with 46 MeV α-particle. Possibility of separation of no-carrier-added (NCA) polonium radioisotopes from the bulk lead-bismuth eutectic target was explored. Differential precipitation showed presence of Po with bulk Bi, leaving behind bulk Pb in aqueous medium. NCA ²⁰⁶Po radioisotope was then separated from bulk Bi using trioctylamine (TOA) as the extractant. At best condition of 0.01 M TOA+0.1 M HCl, highest separation factor (>500) was achieved between NCA Po and bulk Bi.

从α粒子辐照的铅铋共晶靶中分离²⁰⁶ Po

用46 MeVα粒子轰击铅铋共晶（LBE）靶。探索了从大块的铅-铋共晶靶中分离出无载流子（NCA）radio放射性同位素的可能性。差异沉淀显示存在带有大块Bi的Po，而在含水介质中留下大块Pb。然后，使用三辛胺（TOA）作为萃取剂，将NCA ²⁰⁶ Po放射性同位素与主体Bi分离。在0.01 M TOA + 0.1 M HCl的最佳条件下，NCA Po和本体Bi之间实现了最高分离系数（> 500）。
