Cumulative flux of suspended 137Cs in the rivers in Fukushima area. The graph on the left shows the total fluxes since June 2011 for the six sites (nos. 1‒6) where turbidity has been observed since 2011. The graphs in the center and on the right show the accumulated fluxes since October 2012 for the other sites (nos. 7–11, 13–16, 19–30).
