摘要: <正> ~(55)Fe是人工放射性同位素。它的半衰期为2.6a,K电子俘获后放出锰的特征X射线,能量为5.9keV。利用加速器和反应堆都能获得同位素~(55)Fe。然而用反应堆辐照方法制备~(55)Fe要比用加速器制备同位素的成本低得多,并能大量生产。利用反应堆辐照方法制备~(55)Fe是选Abstract: A method of ion exchange for the purification of radionuclide ~(55)Fe produced by irradiation in the nuclear reactor is presented. Radionuclide ~(55)Fe was purified by the anion exchange resin of type-717 made in China in the hydrochloric acid system. Radioactive impurities with energies>100keV in the purified ~(55)Fe was less than 10~(-6).
