> A run on potassium iodide tablets on the US west coast is just plain silly, but the way to combat that is to discuss exactly how radiation spreads, not to try and argue that Fukushima isn't that bad.

How can I do one without doing the other, given the nice "radiation plume" graphics, in "arbitrary units" no less, going through the news?

I'm not trying to minimize the problems, I'm trying to be realistic about them. After the first hydrogen explosion, if you look through my HN comments, I warned that there were likely to be more. Those are very dangerous, but to the plant employees fixing this, but not to anyone who isn't nearby. Those people are heroes, putting themselves in danger to protect everyone else from further radiation leaks.

But I sincerely believe that nobody who isn't in Japan or in the sea nearby is at any serious risk.
