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 CuKα of the base material which was excited by β-particles and the 55Fe-activity was determined from MnKα 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.
