Geographic and vertical distribution of Cs-137 in soils in Canada

A model of 137Cs activity profile for soil erosion studies in uncultivated soils of Mediterranean environments

“…This surface deposition is known in detail in certain parts of the world (e.g. Blagoeva and Zikovbsky, 1995). At medium latitudes in the Northern Hemisphere, the deposition shows a similar temporal evolution for 90 Sr and 137 Cs in the literature (EML, 1977;Ritchie and McHenry, 1990;Agudo and Garc!…”

Radiocaesium fallout behaviour in volcanic soils in Iceland

“…In Chile, based on 29 soil samples, a regression coefficient of 0.79 was obtained between radiocaesium deposition and precipitation (Schuller et al, 2002). In countries with other soil types, such as Germany (Bunzl and Kracke, 1988); Montana, USA (Arnalds et al, 1989); Canada (Blagoeva and Zikovsky, 1995) and Korea (Lee and Lee, 1997), positive correlations have also been reported. The regression coefficients (r 2 ) from these studies generally range between 0.6 and 0.8.…”

Assessing soil redistribution in a complex karst catchment using fallout 137Cs and GIS

“…A 137 Cs linear transference (Smith and Elder, 1999) between each pair of 240 adjoining compartments is supposed, whereby the isotope flux is proportional to the 241 difference in concentration between the two compartments, the proportionality constant 242 being a specific coefficient k. In addition to the downward movement, the model also 243 takes into account the 137 Cs deposition on the surface, which is known precisely in 244 certain parts of the world (e.g. Blagoeva and Zikovsky, 1995). The increases or 245 decreases in concentration level due to 137 Cs fluxes are corrected by a volume factor of 246 the layers.…”
