Gascó, M.P. Antón, P. Rivas] The 239+240Pu, 238Pu and 137Cs distribution along the Almanzora Gulch and beach edge have been studied. These areas were affected by the accident of 1966, in which a non-nuclear explosion of two thermonuclear bombs occurred. Fluvial sediments at 0-5 cm (in 1990) and 0-10, 10-20, 20-30 cm depth (in 1991) were sampled. The surface inventory (0-5 cm) of radionuclides ranges from 0.4 to 1.8 Bq.m-2 of 239-240Pu and from 1 to 60 Bq.m-2 of 137Cs. The estimated total inventory (0-30 cm) shows values from 20 to 264 Bq.m-2 of 239+240Pu and from 328 to 1147 Bq.m-2 of 137Cs. The ratio 239+240Pu/137Cs changes significantly close to the river mouth, probably due to the different behaviour of both radionuclides. At one sampling station a contribution from the Palomares accident was noted based on the ratio 238Pu/239+240Pu. It seems evident that until now no influence from the Chernobyl accident has been detected in this area. The granulometry of the sediments manifests the river hydrodynamics, a dry gulch with periods of floods typical of certain Mediterranean rivers. An important input of terrigenous material containing radionuclides to the adjacent continental shelf occurs in these periods.
