[Pu(IV) behavior in the serum]

This paper presents the results of studies of the hydrolysis and polymerization of Pu(IV) in blood serum. With nitrite Pu(IV) solutions incubated with blood serum 20-34% of the nuclide were precipitated as hydroxide and 11-36% converted into polymeric forms bound by high molecular weight proteins. For citrate solutions, these values were 3.8 and 3.0%, respectively.
