Assessment of soil erosion rates in a Mediterranean cultivated and uncultivated soils using fallout 137Cs.

Journal of Environmental Radioactivity, 2019
Fallout radionuclides, such as 137Cs, have been recognized as a valuable means for studying soil erosion processes. In this study, the 137Cs technique was used to assess soil erosion magnitude and to investigate the effectiveness of terrace cultivations ...

Relationship between the activity concentration of 137Cs in the growing shoots of Quercus serrata and soil 137Cs, exchangeable cations, and pH in Fukushima, Japan.

Journal of Environmental Radioactivity, 2020
Incorporation of radiocesium by plants via root uptake appears to be affected by some of the exchangeable cations in the soil and/or pH of the soil. However, few studies have examined the relationship between 137Cs in trees and soil properties in the ...

Reactive barriers for 137Cs retention

Journal of Contaminant Hydrology, 2001
137Cs was dispersed globally by cold war activities and, more recently, by the Chernobyl accident. Engineered extraction of 137Cs from soils and groundwaters is exceedingly difficult. Because the half-life of 137Cs is only 30.2 years, remediation might be more effective (and less costly) if 137Cs bioavailability could be demonstrably limited for even a

The chemical speciation of 137Cs in sheepmeat

Applied Radiation and Isotopes, 1996
Minced sheep muscle, homogenised liver and fragmented rib or cortical bone, from sheep grazing near Bootle, Cumbria, U.K., which had been stored for some months at -20 degrees C, were extracted at 4 degrees C with an isotonic 0.15 M NaCl-0.02 M phosphate buffer at pH 7.4. Each successive extraction released about 50% of the total 137Cs remaining in the

90Sr and 137Cs as tracers of oceanic eddies in the sea of Japan/East sea.

Journal of Environmental Radioactivity, 2020
Vertical distributions of 90Sr and 137Cs in Sea of Japan/East Sea (SOJ/ES) water in the period of 1977-2010 exhibited a typical diffusion shape with surface/subsurface maxima and decreasing values with increasing depth.

Human Uptake of 137Cs in Mutton

Health Physics, 1993
The uptake of radiocesium from mutton contaminated by fallout from the Chernobyl reactor accident has been studied in eight healthy male volunteers. Each subject consumed, on adjacent days, two meals prepared from the mutton containing a total of 0.8 kBq 137Cs.

Vertical profile of 137Cs in soil

Applied Radiation and Isotopes, 2004
In this paper, a vertical distribution of 137Cs in undisturbed soil was investigated experimentally and theoretically. Soil samples were taken from the surroundings of the city of Kragujevac in central Serbia during spring-summer of 2001. The sampling locations were chosen in such a way that the influence of soil characteristics on depth distribution ...

Biokinetic Model for 137Cs in the Fetus

Health Physics, 1997
The metabolic data for cesium and the biologically similar element potassium in the pregnant woman were reviewed. Due to the rapid growth of the placenta and fetus, the pregnancy was divided into four gestational periods: five through ten weeks, eleven through twenty weeks, twenty-one through thirty weeks, and thirty-one through forty weeks.

Derivation of 137Cs deposition density from measurements of 137Cs inventories in undisturbed soils

Journal of Environmental Radioactivity, 2002
The 137Cs inventories in undisturbed soils were measured for 292 locations across the territory of Vietnam. The logarithmic inventory values were regressed against characteristics of sampling sites, such as geographical coordinates, annual rainfall and physico-chemical parameters of soil.

UPTAKE OF 137Cs AND 90Sr IN RICE PLANTS

Health Physics, 2003
In order to study the transfer of water-borne 137Cs and 90Sr into rice plants, pot experiments were done by growing rice plants on soils taken from rice beds near two nuclear power plants: Qinshan Nuclear Power Plant and Daya Bay Nuclear Power Plant in China.
