The Fukushima Prefectural Government explained that it wrote over the data without saving it. It failed to report the case to the national government. The move has made it impossible for the prefectural government to assess how much radiation residents near the nuclear power station were exposed to shortly after the accident -- although such assessment is required under national government guidelines. It was earlier learned that the prefectural government's analysis of data from radiation monitoring posts was delayed until September last year, and was not reflected in final reports compiled by the government and Diet's respective nuclear disaster investigation committees. The latest revelations could influence discussions by a Nuclear Regulation Authority (NRA) panel on measures to improve methods for monitoring radiation doses in the event of an emergency at an atomic power station. At around 3 a.m. on March 12, 2011, the day after the massive earthquake and tsunami that triggered the nuclear crisis, the Fukushima Prefectural Government instructed the nuclear plant's operator, Tokyo Electric Power Co. (TEPCO), to dispatch employees to accompany prefectural officials for emergency monitoring of radiation, according to the prefecture and TEPCO. The order was issued during a meeting of an accident task force in the town of Okuma in accordance with the prefecture's regional disaster-prevention plan, which was worked out within the framework of the national government's guidelines. At least three people clad in radiation suits, including prefectural government officials, headed to Okuma Junior High School, about five kilometers west of the tsunami-hit Fukushima No. 1 Nuclear Power Plant, on a TEPCO bus carrying a portable dosimeter and dust collectors, among other equipment. They arrived at the school at around 5 a.m., and installed the devices near the school's gymnasium, where about 100 local residents were taking shelter. Even though power supply was cut off in the wake of the disaster, the portable dosimeter functioned properly until the afternoon of that day -- when a hydrogen explosion occurred at the power plant's No. 1 reactor building -- because the device was equipped with a small power generator. However, the prefectural government deleted the data in September 2011 after it collected all dosimeters used for radiation monitoring. A report on emergency radiation monitoring that the Education, Culture, Sports, Science and Technology Ministry compiled in July last year, states that monitoring was first conducted at 8:09 a.m. on March 12 in Okuma -- shortly after all residents evacuated from the junior high school to other places -- using another dosimeter. But the latest findings indicate that the monitoring actually commenced at least three hours earlier. The prefectural government's disaster task force explained that it wrote over the data because the manufacturer of the dosimeter said data could not be taken from the device. "We were preoccupied with other tasks and were late in collecting the dosimeter. The maker told us that data couldn't be taken from the device, and we overwrote the readings because we needed to use the dosimeter to monitor radiation levels in various parts of the prefecture," an official of the task English > The Mainichi > News > Full Story English Top The Mainichi Mainichi Weekly 購読 試読 毎⽇動画 昭和毎⽇ センバツ おすすめ 68 iTunesギフトコードなどが当たる!毎⽇jpユ ーザーアンケート実施中 おすすめ情報 中性脂肪と真っ向勝負! 1⽇1本で約20%も! ニッスイが開発(トクホ)… 50代。髪をあきらめる前に 約83%が継続使⽤を希望の頭⽪ケア >無料モニター募集中!サントリー 1. 3⽉10⽇ WBC 第2ラウンド1組 2. ⼤学⼊試:東⼤で合格発表 3. 選挙:双葉町⻑選 告⽰ 町⺠「バ… 4. 受験と私2013:「⼀度間違えた… 5. 夏⽇:都⼼で25.3度…今年初 … 注⽬ブランド 特集企画 電⼦書籍ライフのスタートを応援! スマホやタブレットで試してみよう ◆毎⽇jp×GALAPAGOS STORE◆ 電⼦書籍デビューキャンペーン企画 実施中! 東海⼤学:海を観察すれば気象が⾒え る。浮遊ゴミ解決の⼿がかりにも 海洋と⼤気の密接な関係から導きださ れるものとは? そして浮遊ゴミ解決 の⽷⼝は? 『横道世之介』等、話題作も読める! 春のおきなわ親⼦孫たびのススメ 読書感想画中央コンクール⼊賞者決定 困ったときはまず相談!「⾏政書⼠」 ロシアの今が分かる「ロシアNOW」 ⼤⼿7社から選ぶ新築マンション特集 ⼈気推理作家が語る「嗜好と⽂化」 話題作が読める!50%ポイント還元も ・私⽴・国公⽴⼤学 ⼊試問題と解答 例 ・学⽣⾷堂 ⼈気&⾃慢のメニュー ・⾼校⽣のための近畿⼤学⽂芸⼤賞 ・第10回グリーンツーリズム⼤賞 ・⾼校⼩論⽂予選通過は誰?発表! ・賢い⼤⼈の実践マネー SNS話題記事 11 shares Japanese electronics makers playing catch-up in tablet market 23 shares High school baseball coach suspended for breaking boy's arm 109 shares Fukushima deletes radiation data needed for exposure assessment 13 shares Fukushima decontamination workers' exposure doses go unchecked 11 shares Shopkeepers in tsunami-devastated town reflect on two years of hardship ニュースランキング
