福岛第一核电站（F-1 NPP）的II号反应堆释放了大量放射性物质。生活在受排放影响地区的人们担心每天摄入受污染食品会导致内部暴露。为了评估人们是否应该关心，合作社福岛（福岛县消费者合作社）对当地居民自愿提供的一套重复膳食中的放射性铯进行了广泛的调查。从2011年11月至2012年3月和2012年6月至2012年9月，通过重复饮食方法进行了分析，每个都涵盖了整个县的100个家庭。在如此分析的200份膳食中，发现12份膳食的铯-134和/或铯-137浓度超过1 Bq kg（-1）。即使在我们调查中放射性铯值最大的情况下，一年中每天食用这类食物所产生的年承诺有效剂量也不超过0.1 mSv。
A large quantity of radioactive materials was released from Reactor-II of the Fukushima Daiichi Nuclear Power Plant (F-1 NPP). People living in the area affected by the release are concerned about internal exposures from the daily intakes of contaminated foodstuffs. In order to assess whether the people should be concerned, Co-op Fukushima (Consumer Co-operative in Fukushima Prefecture) conducted a broad survey of radiocaesium in daily meals for which local inhabitants voluntarily provided a set of duplicate meals. Analyses by the duplicate diet method were conducted from November 2011 to March 2012 and from June 2012 to September 2012, each covering 100 families throughout the prefecture. Among the 200 meals thus analysed, 12 were found to have Cs-134 and/or Cs-137 concentrations exceeding 1 Bq kg(-1). Even with the largest radiocaesium value in our survey, daily consumption of such meals throughout a year gave an annual committed effective dose that did not exceed 0.1 mSv.
