one problem is that because you use transparent overlays for the circles, and also colour coding (darker circles are higher values) you get a misleading appearance in heavily sampled areas (which appear darkly coloured just because they have many readings).
i'd suggest making the circles opaque (i know it's not going to look as nice, but it will be more useful...)

would be more useful if it were to shout measurements in sieverts/hr rather than Gray/hr, but I can understand that would be a hell of a lot more complex ;)
Interesting all the same.

"For X-rays and gamma rays, these are the same units as the sievert (Sv)."

ADD: "Sievert = Biological effectiveness factor unique to the type of radiation * Gray"

True, but Gray is for measurement of absorption by ANY material, Sievert is for measurement of absorption by biological material, so you would also need to apply the tissue weighting factor to the gray/hr measurement.
It shows the highest readings away from Fukushima. Why?

I see values of up to 460 Gy/h on this map, what time unit does [1] talk about that 5 is deadly but 460 is normal?
