In-situ and laboratory study of radiocaesium mobility in freshwater sediments

摘要

The title project was designed to identify areas of our understanding of the transport of radionuclides through aquatic environments and uptake by fish which limit the general applicability of the present generation of mathematical models. The initial programme concentrated on four areas: 1. Chemical processes underlying adsorption onto particles; 2. The processes involved in the enhanced transport of radio-caesium from some catchments; 3. Processes of remobilization in sediments and at the seawater/freshwater interface; 4. Effects of water chemistry and the ecology of aquatic organisms on the uptake, storage and excretion of radio-nuclides. (author). 6 refs., 5 figs. (Atomindex citation 24:037763)
