What, if anything, will the US learn from Fukushima?

With climate change concerns on the table, proponents push nuclear power as a "clean" energy. But the aftermath of the Fukushima meltdown provides one of many reasons why nuclear energy should be examined more closely. It's been nearly three years since the Fukushima Daiichi nuclear disaster, but its effects are still being felt in Japan and elsewhere in the world. Three hundred thousand Japanese refugees still live in makeshift camps, and on the other side of the Pacific, a forthcoming study quantifies the effects of "low" doses of traveling radioactive contamination on children's health in California.
