Investigation of the influence of chamber construction parameters on radon exhalation rate [PDF]
Nukleonika, 2016 Radon exhalation from ground is a process dependent on the emanation and migration of radon through ambient air. Most studies on radon exhalation from soil were performed regarding the influence of meteorological and soil parameters.

Estimation of global radon exhalation rate distribution [PDF]
Estimation of global radon exhalation rate distributionA radon exhalation rate distribution model was developed, which considers dependency on soil water saturation, soil temperature and soil texture. The global averages of the radon exhalation rates were calculated to be 17.5 and 18.0 mBq·m^{-2}·s^{-1} by the model with different input soil moisture data. These values were slightly smaller than the widely-
