Fundamental researches on adsorption state of radiaoactive Cs in clay mineral (aluminosilicate) have become important from the virewpoints of development of decontamination or volume-reduction techniques since the accident of Fukushima Daiiichi Nuclear Power Station. Pinpoint surface chemical analysis with nanometer spatial resolutions focusing on a target sample has been needed. In this presentation, I will show our recent work on nanoscale pinpoint surface chemical analysis for Cs-containing clay mineral by means of synchrotron radiation PEEM at BL17SU in SPring-8.
