Here's some heavy news from the Japanese meltdown site: The water in the basement of Fukushima unit no. 1 is so radioactive that just the steam coming off it is creating radiation levels of 3 to 4 sieverts an hour upstairs, where steam from down below is entering through a "crevice" in the floor. Exposure of 3 to 6 sieverts leads to severe nausea, loss of appetite, hemorrhaging, infection, diarrhea, peeling of skin, sterility, and death if untreated. Nobody but the robots who took the latest measurements will be entering that space any time soon.

Barring a miracle, a lot of that water is going to wind up in the Pacific Ocean, and it would be extremely hard to believe that a great deal of equally nasty liquid already hasn't.
