Fig. 1 Schematic representation of uranium uptake and translocation in plants. Uranium enters
into the soil both from anthropogenic and natural (geogenic) sources. Availability of uranium to
plants depends upon several soilborne factors and plants species for transporting from soil to plants
parts (U, uranium)
