Ever since she was a small child, Samantha Grimaldo has had to carry her voice with her.
Grimaldo was born with a rare disorder, Perisylvian syndrome, which means that though she's physically capable in many ways, she's never been able to speak. Instead, she's used a device to speak. She types in what she wants to say, and the device says those words out loud. Her mother, Ruane Grimaldo, says that when Samantha was very young, the voice she used came in a heavy gray box.
Two years ago today, an earthquake and tsunami triggered a meltdown at the Fukushima Dai-ichi nuclear power plant in Japan. Hundreds of thousands of people living near the plant were forced to flee. The World Health Organization recently predicted a very small rise in cancer risk from radioactive material that was released. For the nuclear refugees, though, anxiety and depression could be the more persistent hazard. Correspondent Geoff Brumfiel traveled to Fukushima prefecture and met victims of the accident to see how they are coping.
