A huge radiation spike of 20,557 uSv/hr occurred today at a high school in Fukushima prefecture, east of Koriyama. This is crazy stuff. The Indiana radiation spike a few weeks ago was on the order of 40 uSv/hr, by comparison. It is not even in an evacuation zone. What a crime against humanity that this area has not been evacuated.
Early in the morning, there was an apparent criticality at the Fukushima plant (check at 0:16). This wind was blowing east to west, and the school is directly west of the plant.
Heads up for later in the week on the west coast (especially Pacific Northwest) for this plume or remnants of it. Lethal. I hope it was a malfunction in the radiation detector.
