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 …

Experimental measurements of permeability as a function of scale as well as direct detection
of flow indicate macroscopic channels are present at a soil site. A model for heterogeneous …

Two test cases from Israel are presented herein employing the decay rate of radon along the
flow path to assess groundwater flow velocities. Groundwater flow reaching the fault zone …

Effective radium concentration ECRa, product of radium concentration and radon
emanation, is the source term for radon release into the pore space of rocks and the …

Directional radiometric surface temperature, TR (φ), from a zenith view angle φ has been
used to estimate surface sensible heat flux with varying degrees of success (Kustas and …

We present the results of one year of continuous radon monitoring at Stromboli volcano
collected at two automated real-time stations. These were deployed on the NE flank (at 520 …

This work aims to evaluate the soil radon gas concentration levels at different depths in Wadi
Nasieb area. The area under investigation is located about 40 km east of Abu Zeneima town …

Radon monitoring at different levels of the cover of the Urgeiriça tailings shows that the
sealing is effective and performing as desired in terms of containing the strongly radioactive …

Naturally occurring radioactive noble gas, radon (222 Rn) is a valuable tracer to study
atmospheric processes and to validate global chemical transport models. However, the use …

Radon generation and transport in porous materials involve solid, liquid, and gas phases in
the processes of emanation, diffusion, advection, absorption, and adsorption …
