An investigation by The Asahi Shimbun shows that a higher level was sought to lower the number of evacuees and thus, limit compensation
But just weeks later, the yardstick was upped to 20 millisieverts per year.
... at a meeting on Oct. 28, joined by Chief Cabinet Secretary Osamu Fujimura and Tatsuo Kawabata, internal affairs minister, the participants appeared reluctant to approve a yardstick other than 20 millisieverts.
“The prefectural government could not function with the population drain under the 5-millisievert scenario,” said a state minister who attended the meeting. “In addition, there were concerns that more compensation money will be needed, with an increase in the number of evacuees.”
The Abe administration in March decided to release by the end of this year a set of protection measures for evacuees returning to areas with doses of up to 20 millisieverts.
The move is apparently aimed at setting the stage for return of evacuees even if decontamination operation fails to achieve the target of 1 millisievert.
The Japan Times reported that
At least 157,000 people fled their homes in Fukushima because of the 2011 nuclear disaster, tsunami, and earthquake. Some 32,000 of them now live in temporary housing developments in the prefecture. Around 59,000 more live in subsidized apartments there. Rent is free but utilities are not.
This arrangement was originally supposed to last for two years.
But more than two years have passed and final compensation settlements from Tepco have not been decided.
Permanent housing for displaced people has not been built;
Much of the evacuation zone ― which includes eleven towns and extends up to 45 km from the plant ― remains uninhabitable.
The government now plans to extend the amount of time residents can stay in the temporary houses to four years.
An earlier investigation by Asahi Shimbun revealed that 60 percent of Fukushima evacuees, roughly 54,000 people, would still be unable to return home by 2017.
The evacuees from the nuclear disaster aren't limited to Fukushima prefecture.
Some residents from Hippo district in Miyagi prefecture, just outside of Fukushima, have said that some radiation levels in their area exceed some of those in Fukushima, and are demanding the same compensation, the Associated Press reported.
Lack of compensation for these people, critics say, is another effort to avoid costs.
"Damages from the nuclear accident do not stop at the border. We hope that the compensation program is carried out in a way that reflects the reality of people's lives," said Koji Otani, a lawyer representing the Hippo residents.
