Thanks for the link!  I'm no expert in neither this nor the Japanese
language but the units in this table is all micro-sievert.  On the
news just now, the radiation levels near the site were reported as
milli-sievert.  So, where this data is collected (Tsukuba) is clearly
much better off than the site.  Looking at Wikipedia (which yes, is
perhaps not the most reliable information source), it gives a list of
benchmarks for one-off incidents like a chest x-ray (0.04
milli-sievert).

With zero knowledge on my part, it seems like if this happened for
just one day, we could probably offset it by having one less chest
x-ray or not taking that European/North American flight we had
planned.  I suppose if they fix the problem, we ought to be ok.  The
worry is just if they can't fix it and the numbers get higher from now
on...

Based on what I've seen in English news and understood in Japanese
news, it seems like the radiation went up in the morning at around 6
am when that explosion occurred.  Things seemed to have gone down
since.  I forgot what was the number recorded this morning; the news
mentioned it for Shinjuku, Chiba, Utsunomiya, and a few other places
around Kanto.
