Functional sorbents for selective capture of plutonium, americium, uranium, and thorium in blood.
Self-assembled monolayer on mesoporous supports (SAMMS) are hybrid materials created from attachment of organic moieties onto very high surface area mesoporous silica. SAMMS with surface chemistries including three isomers of hydroxypyridinone, diphosphonic acid, acetamide phosphonic acid, glycinyl urea, and diethylenetriamine pentaacetate (DTPA) analog were evaluated for chelation of actinides...
متن کاملPlutonium and Americium in the Cephalopod Octopus vulgaris
Radiotracer experiments using the photon-emitters 2 3 7 ~ and 2 4 1 ~ m were performed to examine uptake, tissue distribution and retention of plutonium and americium in the cephalopod Octopus vulgaris Cuvier. A 2 wk exposure in contaminated sea water resulted in twice as much 2 3 7 P ~ being taken up by whole octopus as 2 4 1 ~ m . Immediately following uptake approximately 41 % and 73 % of th...
متن کاملPlutonium and uranium in Japanese human tissues.
Plutonium and uranium in human tissues obtained from residents of the Tokyo area were determined by a-spectrometry and the fission track method, respectively. The distribution pattern of each element was estimated on the basis of mean concentration obtained. Plutonium is concentrated in some special organs, while uranium is distributed rather generally throughout the whole body. This difference...
متن کاملGamma Assay of Uranium and Plutonium 5 v. Analytical Methods and Automated Instruments for the Determination of Plutonium and Uranium
Progress continued on method development for the dissolution of difficult-to-dissolve materials, the automated analysis of plutonium and uranium, the preparation of plutonium materials for the Safeguard Analytical Laboratory Evaluation (SALE) Program, and the analysis of HTGR fuel and SALE uranium materials. The previously developed Teflon-container, metal-shell apparatus was applied to the dis...
متن کاملMulticonfigurational nature of 5f orbitals in uranium and plutonium intermetallics.
Uranium and plutonium's 5f electrons are tenuously poised between strongly bonding with ligand spd-states and residing close to the nucleus. The unusual properties of these elements and their compounds (e.g., the six different allotropes of elemental plutonium) are widely believed to depend on the related attributes of f-orbital occupancy and delocalization for which a quantitative measure is l...
