Radioecological analysis of the Elbe river. Pt. 1
Description
The Elbe river is pre-loaded mostly by strontium-90 and cesium-137. Experiments carried out in aquaria by means of radiotracers showed that cesium-137 in equilibrium is enriched by a factor 36 in North Sea shrimps. Using the calculated radioecological parameters the radiation exposure via the environmental exposure pathways drinking water-ingestion of fish, milk, meat swimming boating, and the stay at the river banks have been calculated. For the transfer of phosphorus 32 via the food chain Tubiflex-shrimps-flounders, for example, a transfer-factor of 0.11 was found. (DG)

Den Hauptanteil der Vorbelastung der Elbe liefern Sr-90 und Cs-137. Aquarienversuche mit Radiotracern ergaben, dass Cs-137 im Gleichgewicht um den Faktor 36 in Nordseegarnelen angereichert ist. Unter Verwendung der ermittelten radiooekologischen Parameter wurde die Strahlenexposition ueber die Expositionspfade Trinkwasser-Fischverzehr-Milchverzehr-Fleischverzehr-Schwimmen-Bootfahren und Aufenthalt am Ufer berechnet. Fuer die Weitergabe von P-32 durch die Nahrungskette Tubifex-Garnelen-Flundern ergab sich z.B. ein Transferfaktor von 0.11. (DG)
