Radioecological investigations in the Maehring/Poppenreuth area (NE Bavaria)
Description
Radioecological investigations were performed in the vicinity of abandoned uranium exploration mines near Maehring/NE Bavaria. Uranium, Ra-226, Pb-210, Rn-222, Th-230 and inactive trace elements were analyzed in air-, soil-, plant-, water- and nutriment samples. More than 1.200 radiochemical determinations and 200 integrating radon measurements were taken as the basis for the calculation of the radiation exposure of the public. No significant impact resulted from the radon emission of the mines and the already existing radionuclide burden of the receiving creek by the nearby Czechoslovakian uranium mine was not enhanced. The widespread sampling of farm products showed no additional load. Soil samples from vertical profiles gave no signs of groundwater contamination and the Ra-226 and Pb-210 contents of the food corresponded with those in areas with similar composition of soil. The exposure of the public via ingestion was found to be lower than in comparable investigations in the Fichtelgebirge and the Black Forest. (orig.)

Im Rahmen einer radiooekologischen Untersuchung im Bereich der ehemaligen Uranexplorationsgruben Maehring/Poppenreuth (Opf.) wurden Uran, Ra-226, Pb-210, Rn-222, Th-230 und inaktive Spurenelemente in Luft-, Boden-, Pflanzen-, Wasser- und Nahrungsmittelproben gemessen. Mehr als 1200 radiochemische Einzelbestimmungen und 200 integrierende Radonmessungen wurden zur Berechnung der Strahlenexposition der Umgebungsbevoelkerung herangezogen. Ueber den Luftpfad war keine signifikante Umweltbelastung aus den Gruben festzustellen und ebensowenig erfuhr der durch die tschechischen Gruben vorbelastete Vorfluter durch die Grubenabwaesser eine merkliche Erhoehung seiner Radionuklidlast. Die weitgestreute Probenahme im landwirtschaftlichen Bereich zeigten keine zusaetzliche Belastung. Bodenproben von Vertikalprofilen ergaben keine Anzeichen einer Grundwasserkontamination und die Ra-226- und Pb-210-Konzentrationen in Nahrungsmitteln entsprachen denen in Gebieten mit aehnlicher Bodenbeschaffenheit. Die Bevoelkerungsexposition ueber Ingestion liegt unter den Werten, die in vergleichbaren Untersuchungen im Fichtelgebirge und im Schwarzwald gefunden wurden. (orig.)
