Abstract
Differentiation in the geochemical transfer and uptake of the nuclides 228Ra and 226Ra is observed to give high nuclide activity ratios, of 228Ra to 226Ra, ranging from 20 to 200 in sediment humus collected from a river subject to pollution. Differentiation of this nature is also observed in the non-ionic non-dialysable fraction of the Ra activity in river water and may be attributed to preferential complexing of 228Ra relative to 226Ra. Biological uptake of the activities produces a similar effect. The ratios are higher in a natural radiation environment than in a technologically enhanced one, indicating the influence of nuclide availability.
