Outline of Final Research Achievements |
Radioactive strontium-90 scattered by TEPCO fukushima daiich nuclear power plant accident was specifically quantified by conventional inductively coupled plasma quadrupole mass-spectrometry (ICP-QMS) preceded by on-line chelate column separation (based on lab-on-valve) and oxygen reaction (designated the cascade step). The proposed system overcomes the isobaric interference of Zr-90, whose soil concentration exceeds that of Sr-90 by more than six orders of magnitude. In addition, the system requires no ultimate mass spectrometry or radioactive Sr-90 standards.
