Rationale Source term attribution of environmental contamination following the Fukushima Daiichi Nuclear Power Plant (FDNPP) disaster is complicated by a large number possible similar emission source terms (e.g. FDNPP reactor cores 1–3 and spent fuel ponds 1–4). Cesium isotopic analyses can be utilized to discriminate between from different and, if samples are sufficiently temporally resolved, potentially provide insights into extent core damage at given time. Methods Rice, soil, mushroom,...
Radiometric and mass spectrometric analyses of Cs contamination in the environment can reveal location emission sources, release mechanisms, modes transport, prediction future migration, attribution to specific generator(s) and/or process(es). The Subsurface Disposal Area (SDA) at Idaho National Laboratory (INL) represents a complicated case study for demonstrating current capabilities limitations environmental analyses. (137)Cs distribution patterns, (135)Cs/(137)Cs isotope ratios, known...
Current state-of-the-art fission product separations frequently involve multiple independent separation columns and sample manipulation processes; to couple these processes together, evaporation transposition steps are often required. The addition of results in lengthy times, increased analysis costs, the potential for loss, release radioactive contamination. We report a new semiautomated method rapid U, Zr, Mo, Ba, Sr, Te, lanthanide products from irradiated uranium samples. Chemical yields...
Abstract The results of an ab initio study on a family hydroxy peroxy radical–water complexes formed from the oxidation E‐2‐hexenal, which constitutes important component biogenic atmospheric emissions, are reported. Binding energies for β‐hydroxy‐γ‐peroxy hexanal (β‐ and γ‐positions relative to carbonyl) complex γ‐hydroxy‐β‐peroxy predicted be 3.8 3.6 kcal/mol, respectively, computed at MP2/6‐311++G(2d,2p)//B3LYP/6‐311++G(2d,2p) computational level. Natural bond orbital reveals that...
