AbstractAbstract
[en] The DRONES-G system is NUVIATECH Instruments state-off-the-art technology for light airborne monitoring using UAV device as carrier. The system offers an excellent performance for environmental radiation inspection and emergency monitoring. DRONES-G is designed for surveying smaller areas to search for potential contamination, investigation of uncontrolled radioactive sources or for working in spots with hazardous dose level. A wide range of capabilities and flexibility of use are main advantages for DRONES-G radiation monitoring applications. DRONES-G is a modular detection and gamma spectroscopy system independent from drone or UAV carrier operation. The system is self-containing, self-powering and ruggedized for field applications. The DRONES-G system is divided into a Base Module and special Detection Modules that can be attached independently according to the user application. The NAI Gamma Spectroscopy Modules, Neutron Detector Module, Plastic Detector Module, High Dose Level GM Module and Air Sampler Module represent the modularity of the system. (author)

AbstractAbstract
[en] Light atmospheric ions were studied in relation to radon and its daughter products. Air ionisation variability was observed. The relationship between the concentrations of positive and negative ions in dependence on ionizing radiation present and local and microclimatic conditions was investigated. A very good correlation was found between the concentration of light atmospheric ions and volume activity of radon or equivalent volume activity of radon daughter products. Measurements were conducted in karst caves and mine galleries free from external weather influences. Due to a number of factors, negative ions mostly predominated over positive ions. Special attention was paid to the conditions existing at the particular sites

AbstractAbstract
[en] Solvent extraction was described for determining of the americium content in the liquid samples. Arylesters of imidodiphosphoric, imidothiodiphosphoric, imidodithiodiphosphoric acids and tetraphenylimidodithiodiphosphine are used as representatives of bidentate organophosphoric extractants. From the group of tridentate agents, pentaphenyldiimidotriphosphate, was used. The extraction properties of tetraphenyl imidodiphosphates and their sulphur analogues for trivalent americium in 0.1 mol L-1 HNO3 into toluene also in the presence of tri-n-octylphosphine oxide (TOPO) were investigated. The dependences of equilibrium ratios of the americium on analytical or equilibrium concentration of chelating agents, pH, initial concentration of nitric acid and initial concentration of TOPO were studied. The structures of the complexes in the organic phase were determined and the values of extraction constants were calculated. The extracted species were AmA3, AmA3 (HA), the addition of TOPO induced synergistic extraction of AmA3 TOPO. The utilization of sulphur analogues was marginal. (author)

AbstractAbstract
[en] The most suitable scintillation cocktails were chosen for conditions of aqueous and non-aqueous medium. With respect to luminescence yield factors which influences excitation or self-quenching of scintillation solutions were chosen. The Cerenkov radiation detection method was used for the higher activity determination of 90Sr

AbstractAbstract
[en] Analysis of alpha and beta emitters in aerosol filters and swabs of different materials by liquid scintillation counter is discussed. This method appears suitable for fast determination of activity of radionuclides due to direct alpha and beta separation, measurement in 4π geometry and without sample treatment. The selected group of radionuclides was chosen with respect to military significance, radiotoxicity, and possibility of potential misuse. 90Sr and 239Pu were selected as model radionuclides. Three types of filters were examined, and the attention was also focused on optimizing the type and volume of LSC cocktail. The efficiencies for 239Pu and 90Sr were 90% and 79%, respectively. This method was the most effective for the glass fiber filters measured with the MaxiLight cocktail. (author)
