The government kept a report about a study of individual radiation doses around the Fukushima No. 1 nuclear plant — including an area recently released from an evacuation order — under wraps for six months.
The study, which covered the city of Tamura and the villages of Kawauchi and Iitate, showed that the radiation in many areas is still over 1 millisievert per year — a level the government is looking to achieve in the long term.
The government lifted an evacuation order on the Miyakoji district in Tamura on April 1, but the content of the interim report, compiled in October, was not conveyed to its citizens or local governments before the action was taken.
