Outline of Final Research Achievements

A multi-nuclide accelerator mass spectrometry system was developed at the University of Tsukuba. The particle detection system was designed for high-sensitivity detection of Be-10, C-14, Al-26, Cl-36 and I-129 in isotopic-ratio ranges from 10E-10 to 10E-15. We developed the sulfur removal method to reduce S-36 contamination for Cl-36 AMS. AgCl samples were pressed into an AgBr backing in a large Cu sample cathode.The system background for Cl-36 measurements has a Cl-36/Cl ratio of < 3 × 10E-15. Ca-41 and Sr-90 were also successfully detected with the multi-nuclide AMS system. AMS performance is entirely satisfactory for analysis of cosmogenic nuclides in environmental research. Cl-36 and I-129 were measured most frequently in order to investigate the radioactive contamination in rainwater and soil samples, caused by the Fukushima Daiichi Nuclear Power Plant accident. Be-10 and Cl-36 were applied for the tracer of cosmic ray events in the ice core and variations of solar activity.

Academic Significance and Societal Importance of the Research Achievements

大型の加速器質量分析装置により、同位体比10E-10 から10E-15レベルの環境中の極微量核種が検出可能となった。特に炭素14(C-14)以外のBe-10, Al-26, Cl-36, Ca-41,Sr-90, I-129などの長寿命放射性核種について、同位体トレーサーとして環境動態研究に適用することが可能となった。今後、地球環境科学などの自然科学分野や原子力分野などにおいて、応用研究の進展が期待できる。
