3 gru 2019 · ANOVA analysis revealed significant increases in mean radon with increased ceiling height in either the basement/cellar (p < 0.0005), main/ground floor (p < 0.0005) or upper floors (p < 0.005...
1 sty 1990 · The radon atom possesses a stable closed shell electronic configuration which gives it the chemical properties of a noblegas element. It behaves as expected by comparison with the other inert gases in the periodic table including helium, neon, argon, krypton, and xenon.
26 cze 2024 · Compounds: Though rare, radon can form compounds with highly electronegative elements, such as fluorine. Examples include radon difluoride (RnF2). These compounds are generally unstable and of significant interest in research. Isotopes: Radon has several isotopes, with Radon-222 being the most stable and common.
18 cze 2019 · Abstract. Exposure to radon gas is the second leading cause of lung cancer worldwide behind smoking. Changing the energy characteristics of a dwelling can influence both its thermal and ventilative properties, which can affect indoor air quality.
1 sty 1984 · The low solubility of radon in water has a number of implications of biological and environmental significance. Surface waters contain far less radon than groundwaters because of radon's relative affinity for air. Radon dissolved in the blood rapidly seeks equilibrium with ambient atmospheric radon. Radon can be adsorbed onto various solid ...
1 lis 2022 · Gaseous organic compounds such as alcohols, aldehydes, carboxylic acids, aromatic hydrocarbons, and siloxanes, can be directly emitted from building materials and static contents (Chin et al., 2019, Han et al., 2012), occupants and their activities (e.g., cooking, cleaning and burning), or formed from chemical productions such as the ozonolysis ...
24 cze 2023 · This review study examines the relationship between radon and geology, including its origins, transmission, and accumulation, as well as its impact on human health and mitigation strategies. The decay of uranium and thorium produces radon, a radioactive gas.
