While workers who were directly involved with the disaster may be at higher risk of leukemia, thyroid cancer, and all solid cancers, even those living near the plant should be safe, the WHO concluded.

“Outside the geographical areas most affected by radiation, even in locations within Fukushima prefecture, the predicted risks remain low and no observable increases in cancer above natural variation in baseline rates are anticipated,” the report’s summary read.

But not everyone’s mind is put at ease. “The WHO report shamelessly downplays the impact of early radioactive releases from the Fukushima disaster on people inside the 20 km evacuation zone who were not able to leave the area quickly,” Rianne Teule, Greenpeace International nuclear radiation expert, said in a statement. On the other hand, radiation biologist Kazuo Sakai of Japan's National Institute of Radiological Sciences told ScienceInsider that the report may actually overstate some of the risks by using preliminary data that may have overestimated radiation exposure. ...
