Extensive research on the dynamics of radon gas (Rn-222) originating from the radioactive
decay of radium (Ra-226) in geological subsurface media, sheds light on its periodic release …

Radon-222 (222Rn) is a radioactive noble gas with a half-life of about 3.8 days, which is
naturally exhaled from soil into the atmosphere (eg Pal et al. 2015). It originates from the …

At present, Rn subsurface flow can be described only by diffusion and advection
transportation models within porous media that currently exist. Even though the temperature …

Radon-222 exhalation from the ground surface depends upon a number of variables such
as the 226Ra activity concentration and its distribution in soil grains; soil grain size; soil …

Long-term monitoring of Rn-222 and CO2 at a depth of several dozen meter at the Sde-
Eliezer site, located within one of the Dead Sea Fault Zone segments in northern Israel, has …

Radon-222 exhalation flux densities from two different substrates of several metres
thickness, waste rock and waste rock mixed with approximately 30% lateritic material, were …

The temporal and spatial variations in the release rates of radon from earth materials in to air
and water have been widely recognized for several decades. One of the most important …

The temporal evolution of activity profiles of the radon isotope 222Rn in the top 50 cm of soil
is used to quantify diffusive gas transport in the air‐filled pore space. Air is continuously …

Measurements of radon exhalation from a gravely sandy loam have been made in a semi‐
arid climate by using a combination of closed accumulation, flow‐through accumulation, and …

Radon generated within the upper few meters of the Earth's crust by the radioactive decay of
radium can migrate during its brief lifetime from soil into the atmosphere. This phenomenon …
