The indoor 222Rn radionuclide was directly absorbed in typical 20 ml glass scintillation vials by passing −3 dm3 of ambient air through 16 ml of water-immiscible non-volataile scintillation cocktail Ultima-Gold F for 10 min. The activity of radon and its two α-emitting daughters: 218Po and 214Po, was determined with the BetaScout low-background liquid scintillation counter. The limit of 222Rn detection...
W ramach badań dokonano analizy rozkładu stężeń dwóch radionuklidów 210Pb i 210Po w wybranych biomarkerach: mchach Pleurozium schreberi, Polytrichum communei porostach z gatunku Hypogymnia physodes. W mchach aktywności radionuklidów zależą od możliwości akumulacyjnych poszczególnych części morfologicznych biomarkera. Zarówno stężenie 210Pb jak i 210Po wykazują charakterystycz-ne tendencje, przy czym...
