Abstract

The iron radioisotope ⁵⁹Fe/⁵⁵Fe-activity ratio in biological samples (blood samples) was determined by wet-ashing the sample electrolytically precipitating iron from solution on a copper plate and measuring the iron coating activities, ⁵⁹Fe/⁵⁵Fe, with a semiconductor detector connected to a multichannel analyzer. The ⁵⁹Fe-activity was indicated by the CuK_α of the base material which was excited by β-particles and the ⁵⁵Fe-activity was determined from MnK_α X-ray peak. Simultaneous determination of both activities, the simplicity of the measurement and the possibility of observing some disturbing radionuclides (for example, ⁵⁷Co or ⁵¹Cr, if present) are some of the advantages of this measuring method.
