Outline of Final Research Achievements

1. A simple method to monitor a specific gamma radiation mainly of 137Cs deposited on an interested object (e.g., a tree and an area of soil surface) was developed using a set of personalized semiconductor cumulative dosimeter and a custom-ordered collimator.
2. Usefulness of the method was clearly certified by some long-term monitorings of gamma radiation in natural environments which were difficult by existing methods. For example, changes of gamma radiation from tree body differing in potassium fertilization was observed by our method. In addition, our method could exhibit both of drastic and delicate changes in gamma radiation from specific areas of soil surfaces in some river beds and forest floors. These phenomenon would be caused by translocation of contaminated/non-contaminated soils and plant debris with floods/heavy rains and/or seasonal defoliation.

Academic Significance and Societal Importance of the Research Achievements

本手法を用いることにより種々の放射性Csの動態とこれに関連するメカニズムの解明が大きく進展すると考える。また、今後は放射性Csの動態のモデル化、移行予測などへの応用を通じて、被災地の流域管理、林産物の利用における安全性の担保、剪定枝や除染廃棄物の処分・管理等の今般の原子力発電所事故における課題の解決、ならびに今後起こり得る過酷事故時の放射性物質移行予測・対策策定などに活用できると考える。
