"Online gamma spectrometry above aerosol filter"@en . . "Within the frame of research project MOSTAR, possible uses of various types of detectors for online gamma spectrometry above the aerosol filter during sampling were considered. The goal of this work was to compare capabilities of particular gamma-ra spectrometers to detect artificial radionuclides in presence of relatively high natural background of the radon progenies. The comparisons of different detectors with respect to energy resolution, effficiency a and detection limits were performed. Detection limits were determined for energy regions of radionuclieds typically present in the air in case of NPP accident. Measurement were done with high volume aerosol samplers with flow rate 900 m3/h (Snow White) and 150 m3/h (Hunter), respectively. Four types of spectrometers were tested- semiconductor HPGe, CdZnTe and scintillation LaBr and NaI(Tl). Variation of concentration of radon in outdoor air and deposition inhomogenity were also included in the analysis."@en . "RIV/86652052:_____/13:#0000291" . .
