放射性セシウムの分布状況を詳細に調査するため、KURAMA-IIモニタリングシステムを背負って歩行しながら空間線量率を測定する歩行サーベイを実施した。走行サーベイによる道路上の空間線量率及び平坦地上1m高さの定点測定による空間線量率との関係を調べた。

The distribution of radioactive cesium were examined by man borne survey method by using KURAMA-II monitoring system. The correlation between the air dose rate measured by man borne survey method and the air dose rate measured by survey meters at 1 m above ground were examined. The correlation between the air dose rate measured by man borne survey method and the air dose rate measured by car borne survey were examined.
