Even that seems a bit questionable... Living near Tokyo, after 3/11 I rather compulsively monitored the various web-available radiation counters, and many of them also stored historical data. The readings were almost universally so close to normal background radiation levels that it was questionable whether there was any difference at all. There was, as I recall, one notable spike at some point, but it was only notable because it was above background level; it was way too small to have any health impact. [Radiation levels were a little higher in places like Chiba that are closer to Fukushima, but still quite firmly in the "no possible effect" region.]
