Abstract
The invention is a radon gas adsorber for buildings which comprises an open-cell material containing activated carbon and attached to a backing material providing high resistance to radon gas flow. The adsorber, which traverses the bottom of the building, prevents entry of radon gas into the building from the ground below it by resisting the gas path with the backing material and adsorbing the gas with the activated carbon.
Claims19
A radon gas adsorber for a building with a foundation located above foundation soil and beneath the habitation areas of said building, which comprises:
- a sheet comprising an open-cell material containing activated carbon and attached to a backing material providing high resistance to radon gas flow,
- said sheet transversing the bottom of said building between said foundation soil and said habitation areas, and
- said sheet being oriented so that the open-cell material is in the down direction, and the backing material is in the up direction.
A broad, relatively thin sheet comprising an open-cell material containing activated carbon and attached to a backing material providing high resistance to radon gas flow.
