,Uranium speciation in two Freital mine tailing samples: EXAFS, µ-XRD, and µ-XRF results,r silicates by inner-sphere complexation; the second pool is represented by the relatively insoluble U(IV) minerals pitchblende and coffinite, and by the U(VI) solids uranyl hydroxide and vanuralite. Distribution between the two pools seems to be controlled by pH. Evidence for reductive precipitation of uraninite was found.

Site characterisation of the potential Natural Analogue Site Heselbach in Bavaria/Germany,ite and clay sediments. Geology, hydrology and radiochemistry were studied in order to get detailed information on these topics. Subsequent to the experimental investigations a uranium transport model has been developed.

Influence of allochthonous plant litter on the fixation of Uranium in sediments,er cones (app. 700 µg*g. *DM.). Compared to leaves from oak alder leaves contain significantly more uranium. Washing partially removes attached particles from the leaf surface. Uranium concentrations in unwashed alder leaves were usually smaller than in washed samples (<2000µg*g. *DM.).
