In order to understand the chemical form of particulate solids contained in the retained water at three locations of Fukushima Daiichi NPS, the chemical species of Fe which is the main constituent element of solids were analyzed with Mssbauer spectroscopy. Most Fe was found to be -form Fe(III) oxyhydroxide. Small amounts of Fe(II) hydroxide and magnetic substance were also detected in the torus and tank samples, respectively.
