Abstract: Inventories of plutonium radionuclides greatly in excess of
global fallout levels persists in the benthic environments of Bikini
and Eniwetok Atolls. It now appears that the atolis have reached a
chemical steadystate condition with respect to the partitioning of /sup
239 +240/Pu between solution and solid phases of the environment. The
mobilized /sup 239 +240/Pu has solute-like characteristics, passes
rapidly and readily through dialysis membranes, has adsorption
characteristics similar to those of fallout plutonium in the open
ocean, and exists in solution primarily as some oxidized +5 or +6
chemical species. Water-column profiles of /sup 239 +240/Pu taken
outside the atolls show a plutonium excess in the deep water mass.
This
remobilized /sup 239 +240/Pu possibly originates from the contaminated
