Abstract In this work, the radon emanation coefficients for selected building materials that are most often used in Serbia covering floor surfaces (concrete, concrete screed, granite, glazed ceramic tiles, marble, roofing tile, and terrazzo tile) were determined, influence of material structure on their values. The concentration 226 Ra activity samples was determined using gamma spectrometry method. Radon measured with RAD7 device. porosity tested mercury intrusion porosimetry water...

Current interactive computing state-of-the-art environments, libraries, and frameworks open the door for engineers to run their simulation codes in an mode, i. e. allowing estimations of state tendency, as well modifications, during a program runtime without necessity own expertise efficient algorithms data structures, high-performance computing, visualisation. Nevertheless, when it comes real-time response this interaction - namely, keeping connection between user's change its effect...

Apart from the continuous exposure of humans to background ionising radiation, an increased level radiation may also originate use building materials with enhanced radioactivity. Thus, it is necessary examine content radionuclides present in materials, as well corresponding dose which be received by residents these materials. In this paper, particular attention was dedicated finding absorbed rate and annual effective caused presence naturally occurring radioisotopes 226Ra, 232Th, 40K...

It is well known that protection from the external irradiation produced by beta emitters simpler than corresponding shielding of radioactive sources emit gamma radiation. This caused relatively strong absorption (i.e. short range) electrons in different materials. However, for specific attention should be paid to bremsstrahlung radiation induced source encapsulation (matrix), especially with high beta-endpoint energy (1 MeV) are frequently used nuclear medicine. In present work, spectra...
