Abstract
Possibility on carrier-free Fe-59 preparation by Korean TRIGA Mark Ⅱ reactor was investigated, namely average cross section on $Co^{59}$(n,p) $Fe^{59}$ reaction, separation by anion exchange resin and radiochemical purity. Radiochemical purity of Fe-59 separated was checked by the method of ${\gamma}$-ray spectrometry with 256-multichannel pulse height analyzer and of half life determination. This method permits Fe-59 preparation with radiochemical purity of > 99.9%.
