I'd like to see a source for that estimate, because "10% had some sort of physical medical reaction" is quite vague and seems improbably high.

Wikipedia states the episode was viewed by 4.6 million households, of whom 685 (0.001%) were taken to hospital. While 12,000 children reported mild symptoms (0.2%), studies suggest many of these were psychosomatic and triggered more by parents freaking out over exposure (this was huge news in Japan) than the exposure itself.
