South Koreans weary of radiation; some schools close

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.
