137Cs in Wood

2004
Global pollution by artificial radionuclides as a consequence of nuclear experiments or nuclear power plant accidents has resulted in radioactive contamination of trees in forest ecosystems. Processed wood as raw material is permanently present in the environment of humans, thus contributing by its radioactive contamination to an increase in the ...

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 ...

Land use types control solid wash-off rate and entrainment coefficient of Fukushima-derived 137Cs, and their time dependence.

Journal of Environmental Radioactivity, 2019
Understanding solid 137Cs wash-off in sediment sources is important for predicting radiological risks in zones contaminated by the Fukushima Dai-ichi Nuclear Power Plant accident. Yoshimura et al.

137Cs and 40K concentration ratios (CRs) in annual and perennial plants in the Caspian coast.

Marine Pollution Bulletin, 2019
This research attempted to investigate the plant/soil concentration ratios (CRs) of 137Cs and 40K in plants that grow on the Anzali Lagoon of the Caspian coast, Iran.

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.

Quantifying spatial distribution of 137Cs in reference site soil in Asia

CATENA, 2019
Fallout radiocaesium (137Cs) has been used to trace soil migration (i.e., by erosion and redistribution) and soil-to-crop transfer levels of radiocaesium in agricultural fields.

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.

Six-year monitoring study of 137Cs discharge from headwater catchments after the Fukushima Dai-ichi Nuclear Power Plant accident.

Journal of Environmental Radioactivity, 2019
Since headwater catchments are the source areas of 137Cs for downstream river systems, 137Cs discharge from headwater areas needs to be evaluated. Dissolved form (Dissolved), coarse organic matter (Org), and suspended sediments (SS) were sampled and ...

Atmospheric deposition fluxes of 137Cs associated with dust fallout in the northeastern Arabian Gulf.

Journal of Environmental Radioactivity, 2018
For many years, monitoring and determining the radioactivity of 137Cs in the environment has considerable interest. This paper presents monitoring 137Cs deposition fluxes during the period from 2009 to 2011.
