Figure 3

(a) Temporal variation of 137Cs concentration in zooplankton. The data from May 2012 to January 2013 were from Takata et al.7. Errors of the data based on 1σ counting statistics are less than or equal to the size of the symbol. (b) Temporal variation of 137Cs in zooplankton per unit volume of seawater. (c) Temporal variation of 134Cs/137Cs activity ratios in zooplankton. The black line indicates theoretical decay curves for 134Cs/137Cs activity ratios with an initial ratio of 1 on 11 March 2011. (d) Temporal variation of 137Cs/133Cs ratio in zooplankton. The black line indicates the average 137Cs/133Cs ratio in ambient seawater for each sampling period. The error bars indicate the standard deviations of the 137Cs/133Cs ratio in ambient seawater during each sampling period.
