Activated carbon radon adsorption for buildings

摘要

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.
