Transfer of radionuclides and stable elements to foodstuffs in Mediterranean ecosystems

Autor: J.A. Corbacho, Antonio Baeza, M.A. Ontalba, Nicholas A. Beresford, Javier Guillén

Publikováno v: Journal of environmental radioactivity.

Adequate radiological protection requires the quantification of radionuclide transfer to the human food chain, which is essential for the estimation of ingestion doses. Transfer parameters are key inputs for the development of radioecological models

TTPIXE analysis of Guadiamar river sediments collected before the environmental disaster of 1998

Autor: Julia Martín, M.F. da Silva, Miguel Ángel Respaldiza, M.A. Ontalba-Salamanca, Rafael García-Tenorio

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. :825-829

Thirteen sediment samples were collected along the Guadiamar riverbed (SW of Spain) in the spring of 1996 for the determination of their composition by thick target proton induced X-ray emission (TTPIXE), using the accelerator of the ITN (Portugal).
