Distribution of different no-carrier-added radionuclides in Pb and Bi fractions after separation of bulk components of lead bismuth eutectic

Liquid-liquid extraction of No-carrier-added 129Cs with various extractants

Two different iodide targets, BiI₃ and KI were irradiated by α-particles to produce ¹²⁹Cs via ¹²⁷I(α, 2n)¹²⁹Cs reaction. ¹²⁹Cs was separated from bulk Bi (when BiI₃ was used as target) by anion exchanger TOA dissolved in cyclohexane. Irradiation of KI with alpha particle produced ¹²⁹Cs along with minute amount ^44mSc. ^44mSc was successfully separated from ¹²⁹Cs using 18-crown 6 ether dissolved in nitrobenzene.

Separation of 71,72As from alpha particle induced gallium oxide target by solid cation and anion exchangers, DOWEX-50 and DOWEX-1

46.0 MeV alpha particle induced reaction on gallium oxide target results production of no-carrier-added (NCA) ^71,72As and ⁶⁷Ga tracer. ^71,72As were separated from the target matrix by solid liquid extraction (SLX) using two different exchangers, Dowex-1 and Dowex-50. At best condition of 0.2 g Dowex-1 + 6 M HCl and 0.2 g Dowex-50 + 10^-3 M HCl bulk gallium was completely extracted leaving behind NCA ^71,72As in the aqueous phase. Dowex-50 was found to be more suitable and offered high separation factor, 3.2 × 10⁵.
