It is just a matter of how you define the problem, and Koriyama City in Fukushima Prefecture, in the high-radiation "Nakadori" region, has decided to "define out" the problem by drawing the radiation contour map of the city with a new set of color schemes so that people will feel "safe and secure" looking at such "low" radiation levels.

The map used to have 1.49 microsievert/hour as maximum, in red color. Now, in the new version of the map that accompanies the Koriyama City's official decon plan, 45 microsieverts/hour is the maximum in red color. 1.5 microsievert/hour area is now in a calming, safe-looking extremely light blue.
