I don't doubt that there is a big screw up there in Japan but I don't see decent reporting on either side of it (maybe I haven't looked hard enough).
Reading about the amount of Cs137 laden water stored suggests there is a hell of a lot -- 100's of 1,000s of tonnes. And I don't like the idea of it getting into the Pacific (which I border too) much at all.
However, what I'd like to see is a measure of what fraction of the radiation I get anyway this represents. How radioactive is a 'normal' sample of Pacific seawater?
I lazy quick look at wiki suggests that the Fukushima release might be of an amount of radioactivity about the size of what has been dumped into the oceans before the 1993 ban. So it is not to be ignored at all.
But it also hasn't all gotten there (yet?) and I suggest that doubling the man made dump into the oceans isn't by itself and "apocalypse".
