I think it is also important to remember that the media will always reach for the worst situation and make uninformed statements at the same time.
The Japanese governments last statement was that the situation is "not stable"..which doesn't mean a giant radioactive plume will engulf the whole island.
If the outer containment is compromised, OK that is bad, and could be a major problem for years to come...but as I am learning about this...it seems even that will not be a real "holocaust" type of fallout.
A GIANT problem, devastating to the whole area as it just lost it's source of power, and a facility that will be uninhabitable for generations...but if I hear right hear...very, very small chance of a Chernobyl level disaster.
I had live feed on from Japanese news and they were saying that the inner containment vessel is breached and leaking. But they don't know if it is leaking liquid or gas. It all depends on where the leak is. If it is leaking liquid then there is no way to cool the fuel. Game over.
They had diagrams provided by the officials and were reporting that radiation had spiked to over 9000microseiverts. I also read that pressure within one of the containments is falling on it's own, no idea what containment that is.
The worst case scenario seems to be widespread contamination of heavier elements with longer half lives than iodine. On an island the size of Japan, one nuclear bomb wide, with 120 million people, well they would be in a world of hurt.
