It is heavier than air but not like a liquid, my suggestion would be to to either go the proven route or double up on a nice visqueen vapor barrier, remember its an accumulative gas. anita Bell Posts: 8 posted 15 years ago Radon is the number 2 cause of Lung Cancer in the United...
Theoretical studies have concluded that prevention of radon influx into buildings by installation of a radon barrier is highly cost effective in most cases (Gray et al., 2009). Further, recent studies in Finland (Arvela et al., 2012) and Ireland (Long et al., 2013) suggests that specific...
The air containing radon and thoron from this compartment diffuses to the second compartment (named as “radon” chamber) through pin-holes, acting as a diffusion barrier that cuts off the entry of thoron into this chamber due to its short half-life (55.6 s). Hence, only radon enters ...
Similarly, the WHO [1] argues that in many cases, it would be cost-effective to install radon prevention measures such as a radon barrier in all new buildings. These recommendations are relevant for Ireland, where current building regulations require the installation of a standby radon sump in ...
Special attention must be focused on the risk of mold growth, for example, in an air cavity behind a radon barrier that is not bonded to the underlayment. Through diffusion, radon can penetrate the ground slab or basement wall and floor. The ability of gases, vapors and other minor ...
, sandy or gravelly soils of the foothill area, whereas fine soils are a natural barrier to the upwards movement of the gas. In this way, alluvial deposits can be identified using the soil map. This has the advantage of describing the peculiarity of the subsoil at immediate contact with ...
