Sorption of actinides, particularly plutonium, onto submicrometer-sized colloids increases their mobility, but these plutonium colloids are difficult to detect in the far-field. We identified actinides on colloids in the groundwater from the Mayak Production Association, Urals, Russia; at the source, the plutonium activity is ∼1000 becquerels per liter. Plutonium activities are still 0.16 becquerels per liter at a distance of 3 kilometers, where 70 to 90 mole percent of the plutonium is sorbed… 
Nature of nano-sized plutonium particles in soils at the Hanford Site
Abstract The occurrence of plutonium dioxide (PuO2) either from direct deposition or from the precipitation of plutonium-bearing solutions in contaminated soils and sediments is well described,
Colloid-Facilitated Transport of Plutonium at the Nevada Test Site, NV, USA
Increasing observations of subsurface actinide transport has reinforced the need for a basic geochemical and hydrologic understanding of how these contaminants are transported in groundwater. At the
Colloid-associated plutonium transport in the vadose zone sediments at Lop Nor.
Plutonium partitioning in three-phase systems with water, granite grains, and different colloids
The results show that colloidal species of 239Pu in three-phase systems remained the highest percentages in comparison to both the dissolved species and the immobile species retained on the granite grains (solid phase), although the relative fraction of these three species depended on the colloid types.
Formation of plutonium(IV) silicate species in very alkaline reactive media.
Studying the speciation of Pu(IV) in very alkaline and silicate ion rich reactive media allowed identification of the formation of plutonium(IV)-silicate colloidal suspensions which were stable for


Migration of plutonium in ground water at the Nevada Test Site
Mobile colloids—suspended particles in the submicrometre size range—are known to occur naturally in ground water, and have the potential to enhance transport of non-soluble contaminants through
Sorption kinetics and impact of temperature, ionic strength and colloid concentration on the adsorption of plutonium-239 by inorganic colloids
Abstract Plutonium (Pu) is one of the primary actinides of concern for long-term disposal and storage of nuclear waste. Strong sorption of Pu onto colloids of iron oxide, clay, and silica could
Mobility of plutonium and americium through a shallow aquifer in a semiarid region
Treated liquid wastes containing traces of plutonium and americium are released into Mortandad Canyon, within the site of Los Alamos National Laboratory, NM. The wastes infiltrate a small aquifer
Mechanism of Plutonium Transport in a Shallow Aquifer in Mortandad Canyon, Los Alamos National Laboratory, New Mexico
Potential environmental effects of radioactive isotopes are of great public concern. Fortunately most long-lived isotopes have strong affinities for solids and limited mobility under natural
Mineral Associations and Average Oxidation States of Sorbed Pu on Tuff
Subsurface transport of groundwater contaminants is greatly influenced by chemical speciation, precipitation, and sorption processes. The transport of Pu potentially released from spent nuclear fuel
Actinide Carbonte Complexes and Their Importance in Actinide Environmental Chemistry
In the last decade scientists have dramatically increased their understanding of the chemistry of actinide elements with a potent emphasis on relevance to the environment. This flourishing chemistry
