The life behavior patterns and the path expected when the residents returned to the evacuation order release preparation area were investigated through interviews, and the air dose rates over the path measured with KURAMA-II. The results of expectation of exposure dose received in daily life when the residents returned to the areas showed that the minimum value of the additional exposure dose of a year was 0.31[mSv] and the maximum one was 2.62[mSv], and that the additional exposure dose of a year for 47 people which is 72% of the subject 65 people was less than 1.0[mSv].

We have been continuously implementing an attempt to accurately estimate the exposure dose when residents return to areas where evacuation order was cancelled, by interview of life action route and measurement of air dose rate covering the whole action route. The survey results for 2017 and 2018 will be reported. From this study, it was found that about 85% of the surveyed people had an estimated annual additional dose of 1.0 mSv or less, and about 90% had an estimated value of 2.0 mSv or less.
