Mapping project in Fukushima and related researches, 9; Estimation of exposed dose by measurement of air dose rate considering daily activity pattern

Sato, Tetsuro*; Ando, Masaki  ; Saito, Kimiaki  

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].
