| Outline of Final Research Achievements |
Multiple measures - including all-bag inspection of cultivated rice and potassium fertilizer application to prevent cesium absorption by planted rice - have been implemented to ensure the safety of rice cultivation in Fukushima Prefecture. This study aims to make these multiple measures more effective by assessing the risks posed by cesium absorption from soil, water and the atmosphere and by making concrete proposals for sustainable radiation countermeasures. In particular, in regard to cases where cesium is absorbed from the soil, this study assesses the mechanism behind this process in different soil types and advances the risk evaluation of soils in the prefecture by making proposals for assessment methods utilizing the cultivation of buckwheat seedlings to assess soil risks. These findings provide highly useful knowledge for the farming guidance efforts and inspection systems of local municipalities and JA cooperatives.
