... gun for accelerating test specimens with a maximum diameter of 43 mm to velocities up to 100 m s −1 , a hard impact surface (unyielding iron plate), and an aerodynamic classification unit ( Fig. 1 ). In the classification unit, all airborne particles with aerodynamic diameters smaller than 100 μm...

... from 2000 to 50 000 compared with in-stack samples. The ratios of As/Cu, Pb/Cu and Zn/Cu for the stack and in-plume samples show good correspondence. The relative fraction of As, Cu, Pb and Zn in the size bins <2 μm, 2–8 μm and >8 μm aerodynamic diameter were established using a cascade impactor...

... and surface properties, as well as the velocity of the air stream in the respiratory system determine the depth to which particles may penetrate the lung. In general, particles with aerodynamic diameters greater than approximately 10 μm impact in the upper reaches of the respiratory tract and are rapidly...

... deposition and also from condensation and interactions on particle surfaces during and following the deposition of soluble fallout. Identification of the presence and nature of hot particles is necessary in order to determine the long-term ecological impact of radioactive fallout. This paper describes...

...' morphologies; some have evidence of minor dissolution, including corrosion pitting. Polycrystalline and often hollow microscopic spheres were identified, which are similar to particles produced by DU munitions impacting armoured targets. They are attributed to the autothermic oxidation of melt droplets...

... particles retained in the filters, following the analytical procedure developed by Querol et al. ( 2001 ). In brief, a half of each filter was digested in closed Teflon PFA reactors with a mixture of HNO 3 :HF:HClO 4 (1:2:1) at 90°C. Subsequently, the acidic solution was cooled and dried on a hot plate...

... regimes of power density, burnup, and fission-gas release. In a reactor of this type, the number of impacts of radiogenic particles is so low that no significant irradiation damage to core materials occurs and hence it has a long life. The space research and development conducted in both the former...

...) is a nondestructive three-dimensional (3D) imaging method. A collimated thermal neutron beam generated by fission of 235 U in a nuclear reactor passes through the specimen. The neutrons can be coherently or incoherently scattered, or absorbed by atomic nuclei within the sample. The remaining neutron flux is imaged...

Since decommissioning of the reverberatory furnaces after 1990, flue gases and dusts at the Horne smelter are produced either in the Noranda smelting reactor or in the secondary...
