Earth ScienceEngineeringマイクロウェーブ加熱分解/誘導結合プラズマ質量分析（Icp-ms）による土壌中の235u及び238uの同位体比分析法を開発した．マイクロウェーブ加熱分解では，硝酸－過酸化水素の混酸を用いることで，ケイ酸塩中の天然ウランの溶解を抑制した．また，同位体比を精確に求めるために，岩石標準物質中のウラン同位体比を実試料の同位体比の指標とし，icp-msのセルパス電圧をmsのマスバイアス校正に利用した．これらの効果により，放射能を含む標準線源を使用せずにウランの同位体比を0.37％ の精度で測定できた．235U及び238uはそれぞれ定量でき，それらの検出下限値はそれぞれ0.010 μG/kgであった．原子力災害などの緊急時において，本法は，従来法である完全酸分解/icp-msあるいはα線スペクトロメトリーと比較すると迅速で広範囲の状況把握が可能である．さらに，東京電力福島第一原子力発電所から7～80Radioactive ContaminationMicrowave Digestion Associated +5
