A comparative study of riverine 137Cs dynamics during high-flow events at three contaminated river catchments in Fukushima

Takuya Niida et al.

Summary: This study examines the temporal variations in riverine Cs-137 concentrations and fluxes to the ocean during high-flow events in three coastal river catchments contaminated by the Fukushima accident. The results suggest that the spatial pattern of Cs-137 distribution in the catchments is the main factor influencing the variations in Cs-137 concentrations, rather than the physico-chemical properties of the water. Additionally, the study finds that sediment from forested areas contributes to the elevation of particulate Cs-137 concentrations during intense rainfall events. The episodic sampling during high-flow events demonstrates that catchment characteristics play a crucial role in controlling Cs-137 transfer to the ocean.

CESIUM-RICH MICROPARTICLES RUNOFF DURING RAINFALL: A CASE STUDY IN THE TAKASE RIVER

Takahiro Tatsuno et al.

Summary: The study found that cesium-137-rich microparticles (CsMPs) were rarely detected in runoff from soil erosion during rainfall in the Takase River watershed in Fukushima Prefecture from the Fukushima accident until July 2021. The proportion of Cs-137 runoff in the form of CsMPs to suspended solids (SS) in the water was small, averaging about 6%.

Sorption and desorption experiments using stable cesium: considerations for radiocesium retention by fresh plant residues in Fukushima forest soils

Takuya Manaka et al.

Summary: Through sorption experiments with stable cesium, we found that bark and wattle tannin sorbed relatively large amounts of Cs, while samples containing clay minerals showed much higher Cs sorption. Desorption experiments suggested that Cs on the organic matter samples were relatively mobile.
