dc.description.abstract | In the last years, 236U (T1/2=2.34·107 y), which is essentially an anthropogenic radionuclide, has been established as a new oceanographic tracer thanks to its conservative behaviour in seawater. At the Centro Nacional de Aceleradores (CNA), in Seville (Spain), it has been recently demonstrated that 236U can be determined at environmental levels on the 1 MV Accelerator Mass Spectrometry (AMS) system. In the framework of the existing collaboration between the National Marine Information and Research Centre (NatMIRC), in Namibia, and the IAEA Environment Laboratories in Monaco, 236U has been analysed by AMS at CNA in a set of seawater samples collected in the northern Benguela upwelling system, on the Namibian coast. In surface samples, 236U/238U atom ratios at the level of 10-10 have been obtained, in agreement with the expected values for the so-called global fallout. The 236U inventories reported up to now in seawater are discussed. | - |
