The six-year anniversary of the nuclear power plant disaster in Fukushima, Japan, was Saturday, bringing with it frightening tales of radioactive boars and wild pigs roaming the deserted streets of abandoned towns near where the plant melted down.

Nuclear radiation levels are so lethal at the plant site that a human would fall to the ground and die in as little as one minute, according to data released last week by the owner of the Daiichi power plant in Fukushima prefecture.
