Abstract It is known that the highest contribution to the yearly radiation dose for the population derives from natural radioactivity. About 50% of that is estimated to be caused by exposure to radon (Rn) and its products. Human exposure to indoor Rn is currently considered a relevant research topic, because of the associated epidemiological aspects. This paper aimed at Rn concentration measurement in a selected building in Košice city, Slovakia. The continuous monitoring of indoor radon levels was performed over a period of 40 days. The measured concentrations ranged in a wide interval up to 92 Bq/m3. The WHO limit value of 100 Bq/m3 wasn´t exceeded. Analysing the possible sources, both contributions of radon from the building materials and radon from the soil was observed.

Modern polishing, precision machining and microindentation techniques allow the processing and mechanical characterization of ceramics at nanometric scales and within entirely plastic deformation regimes. The mechanical response of most ceramics to such highly constrained contact is not predictable from macroscopic properties and the microstructural deformation patterns have proven difficult to characterize by the application of any individual technique. In this study, TEM techniques of contrast analysis and CBED are combined with stereographic analysis to construct a three-dimensional microstructure deformation map of the surface of a perfectly plastic microindentation on macroscopically brittle aluminum nitride.The bright field image in Figure 1 shows a lg Vickers microindentation contained within a single AlN grain far from any boundaries. High densities of dislocations are evident, particularly near facet edges but are not individually resolvable. The prominent bend contours also indicate the severity of plastic deformation. Figure 2 is a selected area diffraction pattern covering the entire indentation area.
