A worst case scenario
What if a sudden explosion or discharge of radioactive clouds from one of the reactors and raising radioactive particles to a dangerous level? Fukushima prefecture no longer habitable and the govt order an immediate evacuation from the area. Radioactive clouds are blown towards Tokyo and a similar evacuation order is made. Can you imagine Fukushima prefecture will be abandoned and left barren for years to come? Can you imagine an evacuation of Tokyo! Just pray the Japanese is able to control the situation and prevent it from becoming a crisis of such a magnitude.
