"The government withheld findings on estimated radiation exposure for Fukushima returnees for six months, even though levels exceeded the long-term target of 1 millisievert a year at more than half of surveyed locations.
Individual radiation doses were estimated to be beyond 1 millisievert per year, or 0.23 microsievert an hour, at 24 of all the 43 surveyed sites, including ones in the Miyakoji district in Tamura, Fukushima Prefecture, The Asahi Shimbun learned April 15.
The revelation comes just two weeks after the central government lifted the evacuation order for the district on April 1."
The Asahi Shimbun had the story April 16, 2014.
