Abstract

“The purpose of this study was to evaluate the effect of induced clay suspensions on the transport of 85Sr and 137Cs in an aqueous environment.

An instrumented flume was used as a model river to simulate an environment typical of a slow-moving, unpolluted, turbid stream. Modified longitudinal dispersion relationships were used to describe the transport of radionuclides in turbid streams. Data were derived from instantaneous release of 85Sr and 137Cs with suspended Attapulgite and Kaolinite clays. Continuous release of 137Cs with an Attapulgite clay suspension helped to establish uptake and transport characteristics for one environmental condition. Aquaria and laboratory studies preceded the model river experiments to define more specifically some of the physical and chemical characteristics.

Suspended clay in the model river system produced a significant reduction in the transport of 137Cs. Conversely, the transport of 85Sr was not affected appreciably since most of the 85Sr remained in solution”—Abstract, pages iv-v.
