SEPARATION AND DETERMINATION OF ALPHA IMPURITIES IN THE ELUATES OF FISSION ~(99)Tc~m GENERATOR

The total alpha emitting impurities in ~(99)Tc~m eluates of fission ~(99)Tc~m generator have been separated by the electrodeposition method and measured by the low-level alpha counter. The electrodeposition yield is about 62%. This method has been used for routine appraisal of alpha nuclide purity of the fission ~(99)Tc~m generator eluates.
