ABSTRACT:
An economical method and apparatus for the removal of airborne radon decay products from indoor environments comprising the circulation of air in the environment with a fan concurrent with generation of ions from an ion generator to create a spatial distribution of airborne charged ions and an electric field gradient which is radially directed from the ion generator. The turbulent convection of air caused by the air circulation allows the radon decay products and particles to which they attach to become more rapidly charged and facilitates molecular diffusion of the particles and radon decay products to nearby surfaces. The electric field gradient causes migration of charged attached or unattached radon decay products toward the walls of an indoor environment whereby they deposit and are removed from the airspace.
