Plutonium velocity in Zea mays (corn) and implications for plant uptake of Pu in the root zone

A transport velocity of Pu complexed with the siderophore DFOB has been measured in corn to be at least 174 cm/h. Based on a calculated plant water velocity, a Pu retardation factor of 1–10 was estimated. Dominant Pu species retardation in soil is typically several orders of magnitude higher than th...
