The authors of Rossi et al. (2013) regret that an incorrect parameter value in their numerical simulations led to an over-estimation of all Cesium-137 concentrations reported in the original manuscript by a factor 10. We would like to acknowledge Professor Michio Aoyama of Fukushima University, Japan, for drawing our attention to this error. Since the Lagrangian approach is linearly scalable, all reported Cs-137 concentrations (i.e. in the abstract, the main text as well as in the original figures 1, 2, 4 and 5) have to be reduced by a factor of 10 to obtain the correct concentrations. While the numerical values have changed, our conclusions remain unchanged.
