Artificial radionuclides ( 60 Co, 106 Ru, 134 Cs and 137 Cs) produced in the nuclear power plants along the Rhǒne valley have been detected in most of the 35 sediment samples collected from the shores of the Rhǒne river in southern France. In one sample traces of 241 Am were found, suggesting the presence of transuranic elements. The wide use of river water for irrigation and the occasional big inundations of the Rhǒne have spread the artificial radionuclides over huge areas, quite far behind the river shores. Although artificial radionuclides are present in fields where food crops are collected, their activity is currently considerably lower than the activity of the natural radionuclides present in the river sediment.
