Radon, Radon Go Away Combating radon pollution will someday be a bigger business than asbestos abatement, according to Current Indoor Air Systems Inc., of Boulder, Colo. In Colorado alone, the cancer-causing gas exceeds federally recommended levels in some 40% of dwellings. The problem: low public awareness. So the VC-backed company is targeting real-estate agents, who get sellers to install a radon-removal system before putting their houses on the

market.
