| Outline of Final Research Achievements |
Radioactive strontium (Sr-90) is one of the fission products in the nuclear reactor. Because of similarity in chemical behavior with Ca, Sr-90 should be continuously monitored in waste water and environment surrounding nuclear related facilities. However, Sr-90 is scarcely-measured radionuclide due to pure beta emitter. Easy and high sample throughput analytical method is required for the long-term assessment of the nuclear reactor in the Fukushima Daiichi Nuclear Power station. Novel analytical system has been developed in combination between the μ-total analysis system (μ-TAS) and triple quadrupole ICP mass spectrometer in this study. Sr can be concentrated 50 times by liquid-liquid extraction using crown-ether on μ-TAS. The coupling of μ-TAS with ICP-MS equipped with ultrasonic nebulizer reached to 10 Bq/L of LOD.
