Outline of Final Research Achievements

The main aim of our research was prediction of the long-term dynamics of radiocesium in the Fukushima forests for evaluation of the forestry perspectives. To achieve this purpose, we conducted monitoring observations at several experimental sites populated with the typical forestry species. We found that even in the areas were the evacuation orders have been lifted the radiocesium concentrations in wood currently may exceed the Japanese national standards. Using the knowledge on cycling of stable chemical elements in forests, we developed the model predicting how the radiocesium inventories in tree compartments will change in the future. Modelling results show that for the principal forestry species, Japanese cedar, decrease of radiocesium inventory in wood will be rather slow. Also, we analyzed efficiency of decontamination and suggested measures for revitalization of forestry at the radioactive contaminated territories.
