- •
The spatial distributions of the radiocesium concentrations on the flood plains are heterogeneous.
- •
The air dose rates in the flood channels are higher than those at the edges of the river channels.
- •
The number of points with high radiocesium concentrations in the flood channels is limited.
- •
Vegetation in the flood channels affects the radiocesium deposition process.
- •
A conceptual model of the deposition and transport of radiocesium was constructed.
