震災起因漂流物：Tsunami debris widespread in Alaska, but not radioactive, says group (Alaska Dispatch) | 海ごみ情報 | 海ごみプラットフォームJAPAN

Surveyors examining several Alaska beaches for Japanese tsunami debris found fuel canisters and scores of Styrofoam blocks and oyster floats, but not a hint of radiation associated with the trash, according to a new report. Some fear the meltdown of the Fukushima nuclear reactor that followed the massive tsunami in March last year would have contaminated the flotsam with radiation.
