Objectif Soil to plant transfer factors for radionuclides and the speciation of radionuclides in plants and foodstuffs have been studied. The uptake of americium-241 by vegetation growing on mineral soils of pH greater than 7 could be significantly increased by the application of herbicides containing glyphosate. The uptake of plutonium-239, americium-241 and strontium-90 to barley from the 3 principal agricultural soil types, loam, peat and sand, decreases with time after contamination whereas the uptake of caesium-137 may actually increase with time in predominantly peaty soils. Soil solution has proved to be a useful medium for studying the transfer of radionuclides from soil to plants. A comprehensive chemical analysis of soil solution is required, followed by more detailed speciation studies for polyvalent radionuclides.1. SOIL-TO-PLANT TRANSFER FACTORS FOR RADIONUCLIDES. 2.
