The diurnal evolution of 222-Rn and its progeny in the atmospheric boundary layer during the Wangara experiment [PDF]

, 2007
The diurnal atmospheric boundary layer evolution of the 222Rn decaying family is studied using a state-of-the-art large-eddy simulation model. In particular, a diurnal cycle observed during the Wangara experiment is successfully simulated together with ...

Estimation of global radon exhalation rate distribution

Estimation of global radon exhalation rate distribution
A 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-
