Abstract

Technetium-99 is one of several long-lived fission products which, when detected in the environment can give an indication of a specific nuclear activity. The most sensitive analytical technique for 99Tc yet reported is by isotopic dilution mass spectrometry with technetium-97 as the yield tracer. A method for the preparation of 97Tc is reported in this paper. 97Tc was obtained by irradiation of a sample of natural ruthenium metal in a high flux reactor. After cooling for 2 years, the technetium was isolated from the sample by technique combining; deposition, solvent extraction, and ion-exchange chromatography techniques. 99mTc and 103Ru were used as radio-tracers for the process. The results showed that more than 70% of the Tc was recovered the decontamination factor is more than 2.3 × 107. The 97Tc was calibrated by isotope dilution mass spectrometry with 99Tc as the yield tracer. The final yield was 29.56 μg of 97Tc suitable for use as a mass spectrometric spike (weight % 97Tc spike: 97Tc, 84.77%; 98Tc, 15.03%; 99Tc, 0.20%).
