Overview of Radiocesium Dynamics in Forests: First Decade and Future Perspectives

Abstract

About 70% of contaminated areas are covered with forests. After the occurrence of accidents, the radiocesium deposited at the time of the accident has migrated within forests, which has been well captured by many studies. Additionally, air dose rates have dropped mainly due to the decay of 134Cs. Herein, the overall radiocesium dynamics were reviewed and shown with the collated datasets. Furthermore, future perspectives of forest radiocesium were discussed with predictions and insights from modeling studies.
