Cesium-137 ( $^{137}$ Cs) of estuary sediment impacted by the FDNPP was measured. Increasing radioactivity was observed from surface to bottom. 90% of the $^{137}$ Cs was strongly bound to clay minerals in the estuary sediments. These results suggest that $^{137}$ Cs is being transported from contaminated paddy fields to the estuary.
