Description
Through 137Cs concentration profiles in sediments from Rochedo Reservoir, it was possible to estimate the amount of this radionuclide (94 TBq) which has reached the Meia Ponte River system, as a consequence of the Goiania Radiological accident in 1987. Based on in-situ measurements as well as on laboratory studies, the influence of NH4+ concentration on the Kd value was also investigated. The results have shown that for high NH4d+ concentrations there is a clear correlation between both parameters. It was also observed the influence on the ageing effect on the 137Cs release from the sediment, as well as of the illite content on it. (author)
