Distributions of 137Cs in sediments of a crater lake: results from Baengnokdam of Mt. Halla, Jeju Island

Vertical and horizontal distributions of 137Cs were investigated in sediment cores of the crater lake, Baengnokdam of Mt. Halla, Korea. The activities of 137Cs in sediments were in the range of minimum detectable activity 0.2–214 Bq kg−1 in the 0–100 cm layer. The inventories of 137Cs were in the range of 7.4–29.7 kBq m−2. The higher total inventories of 137Cs were observed in the middle of Baengnokdam of Mt. Halla, indicating that higher 137Cs in soil sediments of the middle of Baengnokdam of Mt. Halla can be strongly adsorbed on mud.
