Abstract

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.
