Meanwhile in Fukushima, a half-year post-meltdown, the Japanese government announced that it is tightening radiation exposure limits for children at the prefecture's schools, from 20 millisieverts per year down to one.

It says it will not require schools to keep children indoors even if radiation levels exceed the new limits, but recommends that they be promptly decontaminated if they go outside.

You know, the usual elementary school routine: lunch, recess, prompt radioactive decontamination, and then maybe a nap for the younger kids.
