Outline of Final Research Achievements

The present study established the measurement technique of cesium isotopes (radioactive cesium: Cs-135 and Cs-137, stable cesium: Cs-133) using ICPMS. The technique can contribute to the research of radioactive material movement in the environment of agricultural fields, forest, etc, after the Fukushima Daiichi Nuclear Power Plant accident.

Academic Significance and Societal Importance of the Research Achievements

放射性物質の環境動態の把握は,放射性セシウム(135Cs, 137Cs)のみならず安定同位体(133Cs)と合わせて評価することで多くの情報が得られる。それには複数装置によって測定を行う必要があり煩雑であったが、本法の確立により単一装置で簡単にデータ収集ができるようになる。
