“…The same observation was made by Chen et al (2005) for different crop types (pea, brassicas, maize, grass and clover), who found thorium concentrations an order of magnitude greater in roots than in leaves, and by D'Souza and Mistry (1970) who reported that roots retained 99.82% of absorbed thorium in a nutrient solution study of bean plants. A substantial data set was produced by Rayno (1989) during an investigation at a thorium mine site. This showed that root concentrations were always substantially higher than those in shoots for a large number of different plants.…”

The U-238 series of radionuclides is of relevance in a variety of environmental contexts ranging from the remediation of former uranium mining and milling facilities to the deep geological disposal of solid radioactive wastes. Herein, we review what is known concerning the behaviour of radionuclides from the U-238 decay chain in soils and plants. This review is intended to provide a single comprehensive source of information to anyone involved in undertaking environmental impact assessment studies relating to this decay chain. Conclusions are drawn relating to values and ranges of distribution coefficients appropriate to uranium, thorium, radium, lead and polonium in different soil types and under various environmental conditions. Similarly, conclusions are drawn relating to plant:soil concentration ratios for these elements for different plant and soil types, and consideration is given to the distribution of these elements within plants following both root uptake and foliar application.
