A nuclear physicist who has drawn attention for tweeting about fallout from the Fukushima nuclear disaster has admitted that he and a colleague underestimated radiation doses in an article for an international scientific journal. Ryugo Hayano, professor emeritus at the University of Tokyo, said the error, which he recognized on Jan. 8, was “unintentional.” The article, carried in the Journal of Radiological Protection’s online edition in July 2017, listed average radiation doses that were one-third of the actual levels for people in Date, a city around 60 kilometers northwest of the crippled Fukushima No. 1 nuclear plant, he said. Hayano’s admission came after an atomic nucleus expert contacted the journal last year to point out unnatural data carried in the report and call for a correction. The radiation doses in the article were based on figures kept by Date residents after the nuclear accident unfolded in March 2011.
