TEPCO Had the Dust Sampling Data from March 11, and Didn't Tell the Rest of Us Until November 24

From the tweets (here, here and here; in Japanese) of independent journalist Ryuichi Kino, from the TEPCO/government joint press conference on November 24, 2011:

前回聞いたモニタリングカーの仕様、ダストサンプリング、空間放射線量率、中性子、風向風速設備などありと松本さん。で３月11日からダストを採っていたのではないか？と聞くと。採っていたと、サラリと。当時は採ってないという説明。

Specs of the monitoring car that I asked about in the last press conference: dust sampling, air radiation level, neutron detection, wind speed and strength, etc., according to TEPCO's Matsumoto. So I asked, "Weren't you then doing the dust sampling from March 11?" Matsumoto answered as a matter of fact, "Yes." At that time in March, TEPCO said they weren't.

東電が初めてダストサンプリングを発表したのは21日頃だったかな。１８日と19日に採取したものを福島第二に持っていって分析という説明だった。１Fの分析装置が使えなくなったので、当初はサンプリングもしてない、必要はないという話だった。

I think it was March 21 when TEPCO announced the result of the dust sampling for the first time. The explanation was that the samples were collected on March 18 and 19, and they were brought to Fukushima II and analyzed. Since the analyzer at Fuku-I was unusable, they weren't doing any dust sampling, there was no need - that was the explanation.

松本さんの話では、分析結果は保安院のＨＰに出ていることを確認していると。なんで東電のＨＰに出てないかは確認するらしい。３月の情報公開の姿勢は、大問題だな。。。当時にダスト分析が出てれば、炉心溶融の証拠にもなっただろうに。隠したのかあ。

Matsumoto said he confirmed that the data was uploaded at the NISA's home page, and he will find out why it is not on TEPCO's home page. This TEPCO's attitude toward disclosure of March information is very problematic... If the result of dust sampling analysis was disclosed at that time, it might have proven the core meltdown. Did they hide?

I wonder. If you believe TEPCO (and the government), you will ______ (fill in the blank as you like).

I'll try to find that data on the Nuclear and Industrial Safety Agency's website tomorrow.
