In one of the first estimates of when Fukushima evacuees may return to their homes, the mayor of one nearby town is telling former residents that it could be 30 years away.
Katsutaka Idogawa, mayor of Futaba, a town close to the crisis-struck Fukushima No. 1 nuclear plant, unveiled the provisional estimate during an address to his staff on Jan. 4.

He said 30 years is a realistic goal because that is roughly the half-life of radioactive cesium-137.
