Outline of Final Research Achievements

Major sources of radioactive contamination for paddy field in Fukushima area could be the irrigation water from river water because radioactive concentration in river water seemed to be increasing. This research had conducted to quantify radioactive cesium amount in irrigation water and paddy soil. As a result of quantification, the total amount of radioactive cesium in irrigation water through one season showed less than 1 % of that residue in paddy soil.
