Experimental study on radon exhalation characteristics of coal samples under varying gas pressures

Results in Physics, 2018
Coal and gas outburst during underground mining operations negatively affects the mining safety and decrease the mining productivity. Current outburst prediction has been largely relying on seismic monitoring which is passive and extremely difficult to ...

The European Radon Mapping Project [PDF]

, 2013
There is almost unanimous agreement that indoor radon (Rn) represents a hazard to human health. Large-scale epidemiological studies gave evidence that Rn is the second-most important cause of lung cancer after smoking and that also relatively low Rn ...

A study of radon emitted from building materials using solid state nuclear track detectors

Journal of Radiation Research and Applied Sciences, 2015
Radon is a natural radioactive gas derived from geologic materials. Inhalation of the short-lived decay products of radon has been linked to an increase in the risk of developing lung cancers if present at elevated levels.

Exhalation rate of radon-222 from concrete and cement mortar

Nukleonika, 2018
The main sources of radon in the air of dwellings are soil, building materials, and groundwater. This study aimed to determine the exhalation rate of 222Rn from samples made of concrete and cement mortars, as well as to evaluate by means of gamma ...

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 ...
