Description
Sediment trap observations of lakes in western Japan before and after Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident indicate that changes in the radioactive Cs discharge are influenced by fluctuations in precipitation and geomorphological conditions in each catchment. Contributions of FDNPP-derived 134,137Cs to the sediment decreased from 19–48% to 10–15% within a few months, implying that the major transport processes of FDNPP-derived 134,137Cs have changed from direct fallout to transport by soil particles. - Highlights: • We studied lake deposition records of radioactive Cs from Fukushima Dai-ichi NPP. • Sediment trap observations were performed before and after the FDNPP accident. • Precipitation and geomorphology of the catchment influence Cs discharge. • The contribution of FDNPP to the lake sediment decreased within a few months. • The major transport processes of FDNPP radioactive Cs to the lake have changed
