A big difference in 137Cs inventories based on two individual cores within a shallow lake, east China

Two sediment piston cores (CHX and CHY) collected from Chaohu Lake, east China were tested for 137 Cs. It was found that the two 137 Cs profiles show very different distribution characteristics, with fallout maxima at CHX and CHY of 21.1 and 51.7 Bq/kg, respectively. The inventories of 137 Cs at CHY...

Description
Summary:Two sediment piston cores (CHX and CHY) collected from Chaohu Lake, east China were tested for 137 Cs. It was found that the two 137 Cs profiles show very different distribution characteristics, with fallout maxima at CHX and CHY of 21.1 and 51.7 Bq/kg, respectively. The inventories of 137 Cs at CHY (2268.1 Bq/m 2 ) is more than five times greater than that of CHX, but the 210 Pb inventories at the two sites are very similar. The discrepancy in 137 Cs inventory can be explained by differences in grain size distributions. Higher levels of potassium in CHY than CHX samples also support this.
