The radiation contamination area map outside of 80km from the plant.

Hopefully, this area map shows extra information from out of the 80km range at Fukushima. It seems the US government's decision on suggesting Americans living within 80km from the plant was right. Did the Japanese government said 20km? Or was it 30km? That's quite accurate for almost deadly serious area. I didn't know if the Japanese government wanted the accuracy range of the area percentage with the contamination close to 100% for the evacuation. But it doesn't help the citizens getting health problems... Seriously, some people needs to think better than the accuracy of the area contamination ratio.
