We have experience of two methods for the analysis of 14C in environmental samples and have used this experience to directly compare these two techniques. Nine vegetation samples and a sucrose standard were analyzed using the benzene synthesis and co

A radioanalytical scheme for determining transuranic nuclides and90Sr in environmental samples
Autor: D. L. Singleton, A. L. Sanchez
Publikováno v: Journal of Radioanalytical and Nuclear Chemistry Articles. 209:41-50
A method is described incorporating the procedures used in the radiochemical assay of Pu, Am and radiostrontium in environmental samples into a single radioanalytical sequential scheme. Sequential schemes have been used for determining the transurani

Modeling and interpreting element ratios in water and sediments: A sensitivity analysis of post-Chernobyl Ru : Cs ratios
Autor: John Hilton, E. Rigg, John Hamilton-Taylor, Francis R. Livens, William Davison, Michael Kelly, D. L. Singleton
Publikováno v: Limnology and Oceanography. 40:1302-1309
When elements are simultaneously added to lakes, experimentally or by accident, their ratios in the water phase and in bottom sediments can change with time due to differential partitioning between solution and suspended particles or sediments. A num

Similarities in the behaviour of Chernobyl derived Ru-103, Ru-106 and Cs-137 in two freshwater lakes
Autor: Francis R. Livens, John Hamilton-Taylor, John Hilton, E. Rigg, Michael Kelly, William Davison, D. L. Singleton
Publikováno v: Aquatic Sciences. 56:133-144
Measurements of the concentrations of Ru-103 and Ru-106 in the water column and sediments of two productive temperate lakes were made during an eight month period following the Chernobyl accident. Ru-103 accumulation in the sediments began simultaneo

The transport of Chernobyl-derived radiocaesium through two freshwater lakes in Cumbria, UK
Autor: William Davison, E. Rigg, Francis R. Livens, T.R. Carrick, John Hamilton-Taylor, D. L. Singleton, John Hilton, Michael Kelly
Publikováno v: Journal of Environmental Radioactivity. 19:125-153
The specific activities of 137Cs and 134Cs in the waters and sediments of Windermere North Basin (WNB) and Esthwaite Water (EW) in the English Lake District were determined over an 18-month period, immediately following the catastrophic accident at t

Temperature dependence of rate constants for reaction of oxygen atoms, O(3P), with allene and 1,3-butadiene
Autor: D. L. Singleton, W. S. Nip, R. J. Cvetanović
Publikováno v: Canadian Journal of Chemistry. 57:949-952
Rate constants were determined for the reactions of O(3P) atoms with allene and with 1,3-butadiene by a phase shift technique in which oxygen atoms were generated by modulated mercury photosensitized decomposition of nitrous oxide and monitored by th

Temperature dependence of the rate constants for the reactions O(3P) + 2,3‐dimethyl‐2‐butene and O(3P) + NO + M determined by a phase shift technique
Autor: D. L. Singleton, S. Furuyama, R. J. Cvetanović, Robert S. Irwin
Publikováno v: The Journal of Chemical Physics. 63:1003-1007
Absolute values of the rate constant k2 for the reaction of O(3P) atoms with 2,3‐dimethyl‐2‐butene are determined over the temperature range 298–481 °K using modulated photosensitized decomposition of N2O to generate O(3P) atoms. The rate co

Temperature dependence of the rate of reaction H+NO+M→HNO+M for M=H2 and the relative third body efficiencies of NO and H2
Autor: R. J. Cvetanović, D. L. Singleton, K. Oka
Publikováno v: The Journal of Chemical Physics. 67:4681-4689
In our previous study of the HNO* (1A″) luminescence in gaseous mixtures of H2, NO, and Hg illuminated by intensity‐modulated 253.7 nm light, we have observed two distinct rates of luminescence decay. Involvement of two distinct HNO* precursors,
