Radiation fear has become part of everyday life for Japanese children in the region around the wrecked Fukushima nuclear plant.
It's been six months since the huge quake and tsunami that unleashed the world's worst nuclear disaster in a quarter of a century.
Playtime for pupils at this school about 25 kilometres from the Fukushima plant is a strictly indoor affair.
School staff monitor radiation levels daily.
SOUNDBITE: Yuka Nagakawa, child club worker, saying (Japanese):
"While radiation levels are at a point where it's alright to play outside, because some parents are worried about it we haven't let the children play outside at all since the disasters."
The Fukushima disaster's taking its toll on education in the region.
Less than half of elementary and just over half of secondary school children have returned to classes since it happened.
Just a fifth of pre-school pupils have come back.
Six months on the owners of the Fukushima plant, Tokyo Electric Power, are still trying to achieve a state of cold shutdown where water used to cool the fuel rods remains below boiling point.
