Check your radiation levels
There's a lot of concern over how much radiation will have escaped from the Fukushima Nuclear Plant by the time it's been completely repaired. So to put things in perspective, here's a broken up version of a chart from Information is Beautiful:
And a link to another version from xkcd. I couldn't break this one up in the same way, and anyway, you need to click though to properly appreciate both charts. If you're concerned, and have found the Information is Beautiful visualisation useful, then you can buy a hi-res PDF of it for a couple of dollars, all of which will go to Japan Crisis Relief.
