- •
Input and output budgets of radiocesium in the mountainous forest of Fukushima were investigated in 2013 and 2014.
- •
137Cs outputs were 4–50 times higher than the 137Cs outputs during the monsoons.
- •
The proportion of 137Cs output to radiocesium inventories was in the range of 0.05%–0.19% during the monsoons.
- •
Radiocesium tends to be preserved in the forest ecosystem due to extremely low output ratios.
- •
The forest floor seems to be a sink of radiocesium contamination than a source for the other ecosystems.
