FUKUSHIMA — When the massive earthquake and tsunami rocked the northeast March 11, residents who had been prepared by years of drills knew exactly what to do: They scrambled for cover until the shaking stopped, then ran for higher ground to avoid the giant waves.

But when word came that the disasters had left the Fukushima No. 1 nuclear power plant leaking radiation, residents were baffled. Should they run? Stay indoors? Drink the water? Eat the food?

Japan, famous for drilling its citizens on how to prepare for all manner of natural disasters, has done far less to prepare those who live near its many nuclear reactors for emergencies. This has left neighbors of the crippled power station confused, misinformed and angry amid the country's worst nuclear accident.
