Abstract
In a study of the contamination by uranium mines in the River Guadiana basin we have found the natural higher concentration of uranium in samples collected near the mines and the expected decrease with distance in samples further away. In spite of this expected result, there is another interesting fact: a natural isotopic separation is observed. Measurements were by alpha spectrometry with a silicon surface barrier detector. The study was completed with total gamma activity at the same sites as for alphas, using an NaI(Tl) detector.Keywords
