Radionuclide transfer from soil to fruit

Journal of Environmental Radioactivity, 2001
The available literature on the transfer of radionuclides from soil to fruit has been reviewed with the aim of identifying the main variables and processes affecting the behaviour of radionuclides in fruit plants. Where available, data for transfer of radionuclides from soil to other components of fruit plant have also been collected, to help in ...

Transfer standard for beta decay radionuclides in radiotherapy

Applied Radiation and Isotopes, 2004
The measurement of the activity of therapeutic radiopharmaceuticals prior to the administration to patients is normally achieved via the use of radionuclide calibrators. An accurate measurement of the activity of pure beta-emitters is complex. Calibration problems can be solved by combining a primary calibration with a 90Y reference solution and a 90Sr/

Soil-to-Plant Transfer of Radionuclides

2000
Transport of radionuclides from soil to plant is determined by both soil and plant factors, as well as by specific environmental circumstances. At polluted sites, the nuclides enter an array of variously bound forms of the same element that are in dynamic equilibria.

Mapping Transfer Parameters of Radionuclides in Terrestrial Environments

2006
Safety assessment models for potential sites selected for underground repositories of high level and long-lived radioactive waste requires the prediction of phytoavailability of such radionuclides at the regional scale. In this context, the areas in which the radionuclides may be highly mobile or accumulate have to be well known, as they will ...

[Radionuclide transfer by migratory birds].

Radiobiologiia, 1992
Evaluation of the zoogenic transfer of radionuclides from the 30-km zone around the Chernobyl NPP was necessary because of the enormous heavily polluted territory and mighty flow of migratory birds who tended to large rivers, the Dnieper and Pripyat.

Placental transfer of positron-emitting radionuclides in metabolic substrates

International Journal of Nuclear Medicine and Biology, 1985
Experimental studies on the biodistribution and placental transfer of in vivo metabolic constituents in pregnant rats were investigated with positron-emitting compounds such as 18F-2-fluoro-2-deoxyglucose, a mixture of 11C-glucose and 11C-fructose, 11C-L-methionine, 11C-D,L-leucine, 11C-adenine, 18F-5-fluoro-2'-deoxyuridine, 11C-S-adenosyl-L-methionine

Transfer of radioactivity to fruit: significant radionuclides and speciation

Journal of Environmental Radioactivity, 2001
One of the roles of the BIOMASS Theme 3 Fruit Working Group was to identify significant radionuclides to support its work programme. This paper provides a short review of radionuclide emissions to atmosphere together with comments on their relative dosimetric impacts to identify those radionuclides most relevant to the Fruit Working Group.

Transfer of radionuclides in animal production systems

2007
Publisher Summary This chapter discusses the transfer of radionuclides in animal production systems. It provides an overview of (1) the most important contamination pathways, (2) fluxes and sinks of radionuclides, (3) how transfer can be described and quantified, and (4) some potential countermeasures.

Horizontal Gene Transfer in Metal and Radionuclide Contaminated Soils

2009
The horizontal transfer of genes encoded on mobile genetic elements (MGEs) such as plasmids and phage and their associated hitchhiking elements (transposons, integrons, integrative and conjugative elements, and insertion sequences) rapidly accelerate genome diversification of microorganisms, thereby affecting their physiology, metabolism, pathogenicity,

Exposure Assessment to Radionuclides Transfer in Food Chain

2007
Generally sites with radioactive contamination are also simultaneously polluted with many other different t oxics, especially heavy metals. Besides the radioactivity, these wastes may also hold different amounts of chemicals, toxic pollutants and precipitates.
