Radioactivity Dynamics in River System

QHow is the cesium concentration in river water changing over time? 【Southern Fukushima prefecture】
AIn all rivers in Fukushima Prefecture, the concentration of radioactive cesium in river water tends to decrease gradually over time.
This is because the concentration of radioactive cesium in sediment discharge from mountain areas is also tending to decrease over time. (see also : Q Is there a continuous input of cesium contamination to rivers from forests?)
