Description

Indirect deposition process of 134Cs and 137Cs beyond river system into Hibara Lake, Fukushima was investigated by analyzing the deposition density of 134Cs and 137Cs and particle size distribution of soil and sediment. Sediment samples of shallow area of lake adjacent to catchment with different slope were used. The sediment depth profile comparison among sampling areas showed faster 134Cs and 137Cs indirect deposition rate in sediment near steep slope area. 134Cs and 137Cs were concentrated dominantly in fine particle, indicating that the 134Cs and 137Cs incorporated to fine particle were dominant species in indirect deposition process.
