"UN scientists have concluded that the Fukushima-Daiichi nuclear disaster is unlikely to push up cancer rates in Japan. Some scientists remain sceptical of this claim, as the findings of the UN’s Scientific Committee on the Effect of Atomic Radiation (UNSCEAR) differ from those of several other studies, including a recent World Health Organization (WHO) report that predicted increased cancer risks among people living in areas with the highest radiation levels."

That's literally the first paragraph of the article you linked. Doesn't sound like there's consensus on the matter.
