High-accuracy mass determination of unstable cesium and barium isotopes [PDF]
Nuclear Physics A, 1999 Abstract Direct mass measurements of short-lived Cs and Ba isotopes have been performed with the tandem Penning trap mass spectrometer ISOLTRAP installed at the on-line isotope separator ISOLDE at CERN. Typically, a mass resolving power of 600 000 and an accuracy of δm ≈ 13 keV have been obtained.

The activity of selected gamma radionuclides in the Tatra National Park
E3S Web of Conferences, 2017 Cesium is naturally occurring active metal, represented by one stable isotope 133Cs, and number of artificial, unstable, isotopes. The most common artificial isotope of cesium is 137Cs, present in the environment of the Tatra Mountains due to nuclear ...

Evaluation of observed and modelled aerosol lifetimes using radioactive tracers of opportunity and an ensemble of 19 global models [PDF]
Atmospheric Chemistry and Physics, 2016 Aerosols have important impacts on air quality and climate, but the processes affecting their removal from the atmosphere are not fully understood and are poorly constrained by observations. This makes modelled aerosol lifetimes uncertain.

Carbon, cesium and iodine isotopes in Japanese cedar leaves from Iwaki, Fukushima [PDF]
Journal of Radioanalytical and Nuclear Chemistry, 2016 Japanese cedar leaves from Iwaki, Fukushima were analyzed for carbon, cesium and iodine isotopic compositions before and after the 2011 nuclear accident. The Δ14C values reflect ambient atmospheric 14C concentrations during the year the leaves were sampled/defoliated, and also previous year(s).

The use of stable Cs and Sr as proxies for the estimation of radionuclide soil-plant transfer factors [PDF]
Ядерна фізика та енергетикаTransfer factors are key inputs for modelling the transport of radionuclides in the environment and for assessment of risk to humans and wildlife. However, for many combinations of soil conditions, plant species (products), and radionuclides, such ...
