The distribution of 137Cs, plutonium and americium in sheep

Science of The Total Environment, 1989
Radiochemical measurements on tissues taken from sheep from the Cumbrian and Lancashire coast have given data which allow the tissue distribution and body content of plutonium isotopes, americium-241 and caesium-137 to be calculated. The data are particularly useful as the concentrations in lung confirm that for these animals the main route of intake ...

Uptake of 137Cs by fresh water fish

Applied Radiation and Isotopes, 2000
The uptake and discharge rates of 137Cs by fresh water fish at different radionuclide concentrations have been studied. A dual compartment model was used to fit the experimental data. The discharge rates have been found to be negligible for the duration of the experiment of 10 d.

137Cs in the western South Pacific Ocean

Science of The Total Environment, 2007
The 137Cs activities were determined for seawater samples from the East Caroline, Coral Sea, New Hebrides, South Fiji and Tasman Sea (two stations) Basins of the western South Pacific Ocean by gamma spectrometry using a low background Ge detector.

The Distribution of Fallout 137Cs in Costa Rica

Health Physics, 1996
Baseline levels of 137Cs on different sites throughout the Costa Rican territory are presented in this study from local and undisturbed soils. They are believed to represent the fallout input to the land surface. Seventy samples were collected from September 1991 to December 1993, and analyzed by gamma spectroscopy.

Evaluating gully erosion using 137Cs and 210Pb/137Cs ratio in a reservoir catchment

Soil and Tillage Research, 2003
Water erosion in the hilly areas of west China is the main process contributing to the overall sediment of the Yellow River and the Yangtze River. The impact of gully erosion in total sediment output has been mostly neglected. Our objective was to assess the sediment production and sediment sources at both the hillslope and catchment scales in the ...

Ingested soil as a source of 137Cs to ruminants

The Science of The Total Environment, 1993
Ingestion of soil has been identified as a potentially important source of radionuclides, particularly to grazing ruminants. Soil artificially contaminated with radiocaesium was administered orally each day for 33 days to Bergamasca sheep and the transfer to milk measured.

2012
The peculiarities of 90Sr and B7Cs accumulation by higher aquatic plants in Kiev water reservoir during 1991???2008 were analyzed. The decline of 90S rand l37Cs specific activity proceeds the last years, but the decrease of 90Sr takes place slower than 137Cs, that causes change of relation of 90Sr to 137Cs toward to decreasing this index.
