New Analysis Shows Fukushima Unit 3 Released High Concentration Of Contamination

Yomiuri Shimbun is reporting a new analysis by Japan Atomic Energy Agency that shows Fukushima unit 3 may have released a high concentration of contamination northwest of the plant. Their analysis assumed that the release happened late in the evening of March 15, 2011 to early morning March 16th. Yomiuri reports that JAEA assumes a venting could have caused the release, but the last venting publicly documented by TEPCO was on 10:15pm March 14th.  If JAEA’s time estimate is correct it is also roughly 12 hours after the unit 3 explosion. Adding to the confusion is the lack of real time radiation monitoring in the evacuation zone before March 15th with some of that data only being found well after the initial disaster had passed.
