<p>Radiocesium, which was deposited in forests due to the Fukushima Dai-ichi nuclear power plant accident, is estimated to remain in the forest for a long period. Forest covers a large proportion of the land area contaminated by radiocesium but there are no decontamination plans for most of the forest area. Therefore, radiocesium is expected to be transferred throughout the material cycle systems in forests and to be taken up by trees. During the approximately 10 years since the accident, many studies on the dynamics of radiocesium in forests have been conducted in the contaminated area. In addition, radiocesium contamination in forests affects headwater stream ecosystems because organic matters such as dead leaves falling from forests are essential nutrient sources for food webs in the ecosystems. There have been several previous studies aimed at understanding the dynamics of radiocesium contamination in the ecosystems through organic matter derived from the contaminated forests. This review introduces previous studies into how radiocesium deposited in forests was transferred through forests and was absorbed by trees. In addition, the process by which radiocesium deposited in forests transfers into headwater streams, and the process of migration into benthic macroinvertebrates, are introduced.</p>
