Plutonium on the Move
Editors' Choice: Highlights of the recent literature,
Several tons of plutonium have
been released into the biosphere since 1941 through nuclear testing, accidental
release, and inadequate waste-handling practices. Plutonium likely enters
soils as Pu(IV) hydroxides and oxides, which have low solubility and adsorb
strongly to mineral surfaces. Therefore, environmental migration is generally
believed to be low (but see Haschke et al., Reports, 14 January, p. 285).
