Movement of /sup 137/Cs by runoff, erosion, and infiltration on the alluvial Captina silt loam
Five mC of /sup 137/Cs were applied in the form of spray to the 5-m/sup 2/ plots of the Captina soil in Tennessee under bare, clipped meadow, and tall meadow cover conditions. During the initial 81-day period agreement was observed between predicted and experimental soil loss. Linear relationship on a full log scale was found between the soil and /sup 137/Cs loss. On the plots with vegetation, it was found that practically all of the /sup 137/Cs applied to the areas covered with vegetation was initially on the plant and litter material. The leaching of /sup 137/Cs from the vegetation began to level off towards the end of the study period (20.5 cm of rain). At the end of the 81-day period, the bare plot had lost 11.9% of the cesium while the clipped meadow and tall meadow plots has lost 5.1% and 2.6% of their cesium respectively.
