In South Korea, some schools closed Thursday because parents were
worried that rain across the country could be toxic.
"We've sent out an official communication today that schools
should try to refrain from outdoor activities," an education
official in South Korea said.
South Korea's nuclear safety agency reported a small level
of radioactive iodine and caesium particles in rain in the south
but said it was not enough to be a public health concern.
Nevertheless, many Koreans donned face masks, and streets
near schools in Seoul were more congested than usual as parents
drove children to work rather than let them walk.
