Abstract

Comprehensive whole-body counter surveys covering over 93% of the school children between the ages of 6 and 15 in Miharu town, Fukushima Prefecture, have been conducted for three consecutive years, in 2011, 2012 and 2013. Although the results of a questionnaire indicate that approximately 60% of the children have been regularly eating local or home-grown rice, in 2012 and 2013 no child was found to exceed the (137)Cs detection limit of 300 Bq/body.

The age distribution of subjects measured in the winter of 2011 (gray bars). Of these children, those who graduated or left the town are indicated by dashed bars, while the white bars indicate children who were newly enrolled in 2012. This graph shows that the mobility of Miharu children is rather low.
