Up-scaling the Application of Fallout Radionuclides to Support Catchment Sediment Management Programmes
The application of fallout radionuclides in soil erosion and sedimentation investigations has provided a valuable tool for improving the understanding of erosion and sediment transfer processes. However, most studies using fallout radionuclides have focussed on small areas. Increasing acceptance of the important role of fine sediment in degrading aquatic habitats and in the transfer and fat...
متن کاملTrace Metals in the Bed Sediment of Small Urban Streams
Trace metals (TMs) are still a serious problem in urban streams because of their toxicity and continuing significant levels in the aquatic environment, especially in bed sediments. Concentrations of Cd, Cr, Cu, Ni, Pb and Zn were monitored in the sediments of several small streams in the Prague area. These streams differ in the main source of pollution (combined sewer overflow CSO, storm water ...

متن کاملRadiological risk analysis of sediment from Kutubdia island, Bangladesh due to natural and anthropogenic radionuclides
To assess the environmental radioactivity levels and hence to determine the population exposure in Kutubdia Island, Bangladesh the sediment samples were analyzed by using gamma ray spectrometry. In those sediment samples the average activity concentration of natural radionuclides 238U, 232Th and 40K were found 15.39±1.67, 38.35±0.76 and 475.51±21.15 Bq/kg respectively. ...
متن کاملSome fallout radionuclides in deep waters around Japan.
Deep water samples collected in 1963 and 1964 in the adjacent seas of Japan were analyzed radiochemically. Sr-90 and Cs-137 were detected in the deep layers down to 6,000 meters deep and showed approximately uniform vertical distributions below 1,000 meters. Mean concentrations of Sr-90 in deep waters were 0.028 ƒÊƒÊc/l in the Pacific and 0.035ƒÊƒÊc /l in the northern Japan Sea, and those of Cs...
