Estimating and predicting chemical potentials, distributions, speciation modes and mobilities of radiometals in soil, water and biomass.

Using a method from coordination chemistry, which is linked to ligand field theory, the interaction of (binding of) metal ions with biomass is described and put to quantitative scales including bioconcentration factors for a given living being. This can be extended to radionuclides and biological exposure to them. Fractionation of radionuclides from fission in biomass is discussed in examples from various taxonomic groups, also touching issues of possible human exposure.
