has been undeniably recognized as the main aetiological factor in lung cancer, but it should …

As an inert radioactive gas, 222 Rn could be easily transported to the atmosphere via
emanation, migration, or exhalation. Research measurements pointed out that 222 Rn …

A comprehensive study was carried out to measure indoor radon/thoron concentrations in
78 dwellings and soil-gas radon in the city of Mashhad, Iran during two seasons, using two …

The release of radon in active fault zones is a sustained radioactive pollution source of the
atmospheric environment. The species, concentration and flux of radon emitted in soil gas in …

Radon flux measurements provide information about how much radon rises from the ground
toward the atmosphere, thus, they could serve as good predictors of indoor radon …

The study shows how geology and tectonic activity affect the soil gas 222 Rn concentration.
