東京電力福島第一原子力発電所の事故で、気象庁が放射性物質の拡散予測を連日行っていたにもかかわらず公開していなかった問題で、同庁は５日、拡散予測を初めてホームページで公開した。
枝野官房長官が４日、公開を指示していた。
この拡散予測は、放射性物質の〈１〉地上への降下量〈２〉大気中の濃度分布〈３〉大気の流れに沿ってどう流されたかを示す「流跡線」の３種類。同原発からの放射性物質の放出量などが不明なことから、同原発から１ベクレルの放射性ヨウ素１３１が放出されたと仮定して計算した。同庁は、これらの分析結果を東日本大震災当日の３月１１日から２３回計算し、要請を受けていた国際原子力機関（ＩＡＥＡ）に１日１～２回、報告していた。

04/04 放射性物質拡散予測、気象庁に公開を指示
東京電力福島第一原子力発電所の事故で、放射性物質の拡散予測を連日行っているにもかかわらず、政府が公開していなかった問題で、枝野官房長官は４日、気象庁に公開を指示した。
ドイツなど欧州諸国の気象機関は、各国の気象機関が観測した風向などのデータに基づき、独自に拡散を予報し、サイトで公開している。噴火時の火山灰や、黄砂の飛散予測と基本的には同じ仕組みだ。
気象庁は、情報発信は原子力災害対策本部に一元化されているため、独自には公表できないとしていたが、枝野長官は記者会見で「少なくとも隠す必要のない情報。誤解を生まないよう十分説明し、公表すべきだった」と述べた。
日本には原子力事故時に放射性物質の飛散予測を行う『ＳＰＥＥＤＩ（スピーディ）』というシステムがあるが、政府は、日々予測を速報するこの情報も公開していないため、原子力関係者らが批判している。

17/03 Japan Offers Little Response to U.S. Assessment

TOKYO — A day after the top American nuclear official portrayed the situation at the troubled Fukushima Daiichi nuclear plant in graver terms than the government in Japan, United States’ most important Asian ally, Japanese officials attributed the diverging accounts on Thursday to a “delay” in sharing information.
But, in public at least, they offered no sharp rebuttals of the comments made by Gregory Jaczko, the chairman of the United States Nuclear Regulatory Commission, that there was little or no water left in a pool holding hundreds of spent fuel rods at Fukushima Daichi’s No. 4 reactor. He also said that resulting high radiations levels could “impact the ability to take corrective measures.”
Most Japanese citizens did not react to Mr. Jaczko’s comments, which presented a far bleaker assessment of the unfolding nuclear crisis, for the simple reason that they went nearly unreported in the Japanese news media.
“There was a slight delay conveying to the U.S. side the information about whether or not there is water,” the government spokesman, Yukio Edano, said about the No. 4 reactor. Mr. Edano was responding to a question asked by a Japanese journalist at a morning news conference — the single one that dealt with Mr. Jaczko’s comments.
But American officials in Japan appeared to continue to operate on the assumption that the danger level was higher than described by the Japanese. On Thursday evening, the United States Embassy in Tokyo offered space aboard chartered planes for dependents of embassy personnel to any American showing up at the two Tokyo area airports, Haneda and Narita. Perhaps because of what such a move implied about Japan’s own assessment of the potential for nuclear fallout, the embassy declined to provide basic details of the flights.
Karen Kelley, a spokeswoman for the embassy, said that embassy officials organizing the charter flights “prefer” not to say how many planes were leaving Japan, how many passengers were aboard or what their immediate destinations were.
American officials also continued to advise Americans to evacuate a radius of “50 miles” from the Fukushima plant, in contrast to Japanese directives that people within about 12 miles evacuate while those between 12 and 19 miles stay indoors. The difference could leave hundreds of thousands of Japanese exposed to potentially dangerous levels of radiation.
Japanese officials did not flatly deny Mr. Jaczko’s comments but hedged. Asked about the level of water in the No. 4 reactor, Yoshitaka Nagayama, a spokesman for Japan’s Nuclear and Industrial Safety Agency, said: “Because we have been unable to go to the scene, we cannot confirm whether there is water left or not in the spent fuel pool at Reactor No. 4.”
The technical nature of the issue perhaps compounded the Japanese news media’s tendency to shield the government. Reporters who cover agencies and ministries are organized in press clubs that have cozy ties with officials and decide what to report — and what not to. The lack of attention received by Mr. Jaczko’s comments was consistent in the news media.
As a result, most residents here were far more concerned with the announcement that a major blackout was being planned to conserve electricity in the Tokyo area. Department stores in this city’s most famous shopping district, Ginza, remained dark as shoppers stayed home. Restaurants closed early as many companies continued to tell their employees to stay home or those working rushed into lightly crowded commuter trains to beat the blackout.
