Recently, first gas-phase chemical experiments aimed to investigate the adsorption behavior of the heavy elements Cn and Fl on selenium surfaces were conducted. During this experimental campaign, an unexpected formation and transport of a volatile At species was observed. Monte-Carlo simulations of the deposition pattern of this species on quartz, selenium, and gold surfaces were performed,...
The techniques of highly sensitive mass spectrometry is achieving rapid development recently. Several elements or nuclides that were not supposed to be applicable in that technique are now quantitatively analyzed. Especially, for long-lived actinides elements, the techniques are becoming more and more important as a promising alternative of radioactivity measurements. The tracer nuclide for...
For now, most radioactive reference sources are manufactured with electro-deposition. However, the electro-deposition procedure takes quite a long period of time and the operations are conducted using flammable solvents under high temperature. In addition, the products of electro-deposition may be oxidized and exfoliate after years of usage which can cause extra uncertainty of quantitative...
Detailed understanding of reactive transport in geomaterials of chemical species, including radionuclides, is required for the utilization of the subsoil, e.g. for designing ore production by in-situ leaching, or for radioactive waste disposal. To complement the well-established conventional approach, i.e. computer model simulations based upon bulk material parameters and geochemical data...
