Here's another article that compares the radiological damage of the Fukushima meltdown to the humanitarian damage done by the response to it. The latter is far worse than the former. The fear is causing more problems than anything having to do with the nuclear effects. Fukushima is nowhere close to the scale for Chernobyl despite the many attempts to put them together.
That the region was rapidly evacuated and everyone told not to eat anything from that area (for two months as I-131 decayed away), was all that was needed to reduce any threat of thyroid effects and all other cancers from most of the affected areas. Japan did this. The Soviets did not. That is why comparisons between Fukushima and Chernobyl fail. That plus Chernobyl released ten times as much radiation into the atmosphere and was a weapons reactor.
