Plutonium 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 americium behaviour in soil-vegetation cover of natural and semi-natural ecosystems
The results of investigations of transuranic elements { H , , M 0 P u and 2 4 'Am) behaviour in the soil-vegetation cover of natural and semi-natural ecosystems in the regions of Belarus contaminated as a result of Chernobyl acci dent have been summarised. The parameters of plutonium and americium vertical migration have been estimated for typical soil varieties; the radionuclides accumulation...
متن کاملTransfer of plutonium, americium and curium from fallout into reindeer after the Chernobyl accident
Several reindeer tissue samples were analysed for transuranium elements following the Chernobyl accident in 1986. Pu, Am and Cm were separated using coprecipitation and anion exchange steps, and measured with alpha spectrometry. The activity concentrations of Pu in reindeer liver found in this study (0.0094–0.062 Bq kg d.w. [= dry weight]) are low compared to the concentrations found in the 196...
متن کاملRelativistic density functional theory modeling of plutonium and americium higher oxide molecules.
The results of electronic structure modeling of plutonium and americium higher oxide molecules (actinide oxidation states VI through VIII) by two-component relativistic density functional theory are presented. Ground-state equilibrium molecular structures, main features of charge distributions, and energetics of AnO3, AnO4, An2On (An=Pu, Am), and PuAmOn, n = 6-8, are determined. In all cases, m...
متن کاملFunctional 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...
