1 sty 2024 · Copper measurements demonstrated a positive correlation between air speed and radon daughter plate-out rate from speeds of 0 to 60 ft/min, stabilizing at speeds between 0 to 60 ft/min. Acrylic...
24 cze 2023 · The daily variations in radon concentration are influenced by various factors such as the rate of radon production, ventilation, and soil moisture. For example, during the day, the temperature and pressure typically rise, leading to increased soil gas flow and radon transport [ 187 , 188 ].
12 sie 2016 · In this chapter, the mechanisms of and factors affecting radon release rates are presented. In-depth discussion on how key parameters such as pressure, temperature, moisture, mineralogy and grain size affect the release rates of radon and its subsequent transport is presented.
A positive correlation between radon flux and radon quantities, such as radon in soil gas and indoor radon, indicates that radon flux could be used as an input parameter for the estimation of RPA.
1 maj 2020 · Dependence of the radon emanation and diffusion coefficient on grain size, moisture content, temperature, pH, and major elemental compositions were examined in this study. The emanation coefficients of radon are strongly influenced by moisture content and grain size of the soils.
5 lip 2021 · The results show that biochar application into the soil contribute to a decrease in the emanation coefficient from a value around 7% to less than 2% with a simultaneous decrease in the radon...
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.
