Abstract

In the course of measurements of uranium contamination in rivers of the Guadiana basin we have found the logical contamination near the uranium mines and a234U/238U ratio near 1 in the neighbourhood of the sources. With distance we find not only the expected decreasing contamination but also higher values of the activity ratio234U/238U. This observation seems to contradict the usual explanation of preferential leaching of234U as origin of the general234U enrichment of ground water.
