Radioecological studies in the Elbe river. Pt. 2
Description
The plutonium contents in water samples taken from the upper Elbe was 5.3 E-05 Bq/l on average from 1979 to 1982 (excluding values below NWC). From 1978 to 1982, in the lawer Elbe 3.3 E-05 Bq/l were measured on average. Most of this activity originates with nuclear weapon test fallout. The activity of the isotope Pu-238 in the fallout is 1/10 to 1/25 of the cumulative activity of Pu 239 and 240. This result is satisfactorily reflected in the measured values shown herein. Specific activity in fish is about 10 times higher (concentration factor 10). In sediments, plutonium is enriched on average by the factor 6000. From 1978 to 1982, the tritium contents in the water of the Elbe was on average 7 Bq/l. The concentration factor for fish meat was determined as 1. The radiation exposure of the population as detemined from the measured activity values are radiobiologically absolutely negligible (whole-body dose < 0.001 mSv/a). (orig.)

Der Plutoniumgehalt von Wasserproben aus der Oberelbe betrug 1979-1982 im Mittel (ohne Werte <N W G) 5,3 E-05 Bq/l. In der Unterelbe wurden im Zeitraum 1978-1982 im Mittel 3,3 E-05 Bq/l gemessen. Diese Aktivitaet ruehrt im wesentlichen vom 'fallout' der Kernwaffenversuche her; die Aktivitaet des Isotopes Pu-238 im 'fallout' ist etwa 10-25 mal geringer als die Summenaktivitaet von Pu-239/240. Dieser Befund spiegelt sich befriedigend in den vorgestellten Messergebnissen wieder. Die spezifischen Aktivitaeten in den Fischen liegen etwa um den Faktor 10 hoeher (Konzentrationsfaktor 10). In Sediment wird Plutonium im Mittel um den Faktor 6000 angreichert. Der Tritiumgehalt des Elbwassers lag 1978-1982 im Mittel bei 7 Bq/l. Als Konzentrationsfaktor fuer Fischfleisch wurde der Wert 1 ermittelt. Die aus den gemessenen Aktivitaetswerten ermittelte Strahlenexposition der Bevoelkerung ist strahlenbiologisch voellig unerheblich (Ganzkoerperdosis <0,001 mSv/a). (orig.)Additional details
