No. 2 reactor source of most contamination

The Yomiuri Shimbun

Tepco has released a new report on radioactive release sources for March 11 thru March 16, 2011. They blame the huge surge of March 15 on unit #2's containment damage. There is absolutely no credit given to the March 15 hydrogen explosion with unit #4. In fact, they seem to be intentionally deflecting interest away from unit #4 detonation's obvious contribution.
