on the one hand it seems like positive news - and we don't want to discount that.

On the other hand ... it's clear to me that not much is understood about Fukushima yet. Now we know that apparently at least one (possibly several) reactors went through melt-downs that were big enough to destroy the reactor containment. So the highly radioactive fuel has leaked out and is .... somewhere. But no-one knows for sure where that is exactly. Possibly somewhere in the ground beneath the reactor building. Do we have some guarantee this stuff won't seep through cracks, get into groundwater, and flow out into the ocean?

Who is really monitoring all these events and being completely open and trnasparent about the radiation risks??
