Fears of child thyroid cancer after Fukushima nuclear disaster

Alerted by the precedent set after Chernobyl, Japanese doctors have set about testing all children who might have been exposed to radiation after last year's nuclear disaster at Fukushima. They're looking for signs of thyroid cancer, and out of the 100,000 children tested so far, 40% have shown some sign of abnormality. With parents struggling to get advice from the authorities, the Fukushima Medical University has had to organise meetings where information can be given out.
