Ministry sorry for school radiation limit flipflop
Japan's education ministry says it is sorry that it initially set the radiation exposure limit for schoolchildren at a high level that drew parents' concerns.

The ministry has drafted a report reviewing its response to the Fukushima nuclear disaster that was triggered by the quake and tsunami on March 11th last year.

The report refers to a decision made in April to set the safety limit of radiation exposure for outdoor school activities at no more than 20 millisieverts per year.
