Samples, collected from the operating floor of the reactor building of Fukushima Daiichi Unit 2, were immersed in deionized water and nitric acid. Immersed solutions were analyzed by gamma-ray spectrometry and ICP-MS. Analyses suggest small amount of Fe, Mn and Cu derived from structural materials of nuclear reactor, and Te, Cs and U derived from spent fuels.
