Gas is generated in the underground and for the most part it percolates to the surface and dissipates under normal atmospheric conditions. Under these circumstances the gas does not constitute a health hazard. However, when buildings are constructed on gas contaminated land, it will seep into buildings through openings, construction joints, cavities and service penetrations to reach a dangerous concentration with a serious health hazard to the inhabitants of the house as a consequence.

Geo-membranes are usually used in civil engineering where you either want to separate different layers of material or where you want to avoid fluids like water and chemicals to undermine the structure of the civil work.

Radon is a naturally occurring radioactive gas entering buildings from the underlying ground. Radon is a colourless and odourless radioactive gas generated by the radioactive decay of radium (Ra226) which in turn derives from the radioactive decay of uranium (U238). Uranium is found in minute quantities in all soils and rocks, although the concentration varies from one geographical location to another.
