Application of mass spectrometry for analysis of cesium and strontium in environmental samples obtained in Fukushima prefecture: Analysis of cesium isotope compositions in environmental samples by thermal ionization mass spectrometry-2

Abstract

For the assessment of Fukushima Daiichi Nuclear Power Plant accident, the applicability of the thermal ionization mass spectrometry (TIMS), which is a type of mass spectrometry, was studied. For the study of the recovery/analysis method of cesium and strontium, at first, the radioactive cesium and strontium were generated by the irradiation of natural uranium at KUR. After this study, the applicability of this method to the environmental samples obtained in Fukushima prefecture was verified.
