Publikováno v: Journal of Radioanalytical and Nuclear Chemistry. 303:719-732

The aim of this study is to confirm and increase the knowledge on anthropogenic radionuclide (RN) behavior (137Cs, 239+240Pu, 241Am) in natural compartments (artificial pool in a protected upland area). The novelty lies on comparisons of the three ma

Publikováno v: Journal of Radioanalytical and Nuclear Chemistry. 298:25-32

This paper reports results on the natural and anthropogenic radionuclides activity concentrations in sediments of the Var river and its tributaries. Natural (238U, 232Th and 40K) and artificial (137Cs) radionuclides activities were measured using hig

Publikováno v: Comptes Rendus Chimie. 12:922-932

A geochemical study concerning surface waters and groundwaters from the Mediterranean Var River catchment (south-east France) is undertaken to better understand this hydrological system and to establish a hydro-geochemical natural background. Prelimi

Publikováno v: Comptes Rendus Chimie. 12:850-853

239–240Pu and 137Cs activities in soil samples were measured in two sites of the littoral part of Cote d'Ivoire: Abidjan and the classified forest of “la Comoe”. Two areas were chosen: a forest and a clearing. The aim of this work is to establi

Behavior of uranium and thorium isotopes in soils of the Boréon area, Mercantour Massif (S.E. France): Leaching and weathering rate modeling

Autor: S. Rezzoug, François Fernex, Hervé Michel, V. Barci, G. Barci-Funel

Publikováno v: Journal of Radioanalytical and Nuclear Chemistry. 279:801-809

Four cores were collected in weathered rocks and soils in the Boreon forest area (1765 m, Mercantour Massif, France). The samples were analyzed for the isotopes 230Th, 232Th, 234U and 238U. The activity and isotopic ratio profiles suggest that uraniu

Radiochemical procedure and quantitative determination of the activation product, 63Ni, in environmental soft water samples with high Ca and Mg phosphate concentration

Autor: G. Barci-Funel, Hervé Michel, V. Barci, Norbert Jordan

Publikováno v: Journal of Radioanalytical and Nuclear Chemistry. 275:253-256

Nickel-63 is a low energy beta-emitter needing a radiochemical separation before β-counting. Several papers described the separation and the detection of 63Ni in environmental samples. The method used in our work was first developed by Skwarzec and

The Boréon area in the Mercantour Massif, S.E. France, was contaminated by radionuclides after the Chernobyl accident in the first days of May 1986. Sediments from a small mountain lake in this area were collected, as well as forest soils in its vic

Publikováno v: Radiochimica Acta. 90:747-752

Summary The record of the global atmospheric fallout could be found in the lake sediments. A mass balance for fallout radionuclides in Blelham Tarn and its catchment is established. The sediment activity contribution is coming from direct atmospheric
