Effect of Carbonation on Radon Exhalation Rate in Concrete
ACI Materials Journal, 2022 Crushed rock aggregates may lead to unhealthy concentrations of radon gas in concrete buildings. The radon exhalation rate isdependent not only on the concrete mixture but also on its microstructure.

Radiation Protection Dosimetry, 1992 By solving the diffusion equation for the axial-symmetric geometry of in situ radon exhalation measurements, the effect of the presence of the measuring device on the exhalation rate was determined. From analyses of the calculated growth curves of the radon concentration in the device it turned out that exhalation rates deduced from measurements ...

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.
