Measurement of plutonium isotopes, 239Pu and 240Pu, in air-filter samples from Seville (2001-2002)
E. Chamizo, M. García-León, S. M. Enamorado +2
Since the last nuclear atmospheric test carried out by the People Republic of China in 1980 and since the Chernobyl accident in 1986, the plutonium hasn't been directly released in…
Characterisation of the plutonium isotopic composition of a sediment core from Palomares, Spain, by low-energy AMS and alpha-spectrometry
E. Chamizo, M. C. Jiménez-Ramos, S. M. Enamorado +6
The measurement of plutonium isotopes, 239Pu and 240Pu, at 670 kV on the compact accelerator mass spectrometry (AMS) system at the Centro Nacional de Aceleradores (CNA) in Seville,…
Isolation of Pu-isotopes from environmental samples using ion chromatography for accelerator mass spectrometry and alpha spectrometry
Elena Chamizo, María del Carmen Jiménez-Ramos, Lukas Wacker +4
A radiochemical method for the isolation of plutonium isotopes from environmental samples, based on the use of specific chromatography resins for actinides (TEVA, Eichrom Industrie…
Excess of U in the northwest Mediterranean Sea
E. Chamizo, M. López-Lora, M. Bressac +2
In this work, we present first U results in the northwestern Mediterranean. U is studied in a seawater column sampled at DYFAMED (Dynamics of Atmospheric Fluxes in…
Isolation of U and Pu from seawater samples and its determination by Accelerator Mass Spectrometry
Mercedes López-Lora, Elena Chamizo, María Villa-Alfageme +3
In this work we present and evaluate a radiochemical procedure optimised for the analysis of U and Pu in seawater samples by Accelerator Mass Spectrometry (AMS)…
Presence of U and Np in a marine ecosystem: the northern Benguela Upwelling System, a case study
Mercedes López-Lora, Elena Chamizo, Martina Rozmaric +1
The Benguela Upwelling System (BUS), off the south-western African coast, is one of the four major eastern boundary upwelling ecosystems in the oceans. However, despite its very in…
Simple and fast method for the analysis of U, Np, Pu and Pu from seawater samples by Accelerator Mass Spectrometry
Mercedes López-Lora, Isabelle Levy, Elena Chamizo
A simple and fast radiochemical procedure for the sequential extraction of U, Np and Pu from small-volume seawater samples ( L) is presented. The method has been developed and…
Anthropogenic actinides in seawater and biota from the west coast of Sweden
Mercedes López Lora, Elena Chamizo, Mats Eriksson
The assessment of the origin of the anthropogenic contamination in marine regions impacted by other sources than global fallout is a challenge. This is the case of the west coast o…
