Low-cost Radon Reduction Pilot Study

The Indoor Climate Research and Training program of the Illinois Sustainable Technology Center, in its capacity as a member of the Partnership for Advancing Residential Retrofit team of the U.S. DOE's Building America Program, is conducting a pilot study on radon reduction through low-cost measures.

The aim of this research pilot project is to study the impact of air sealing between the foundation and the living space on radon transport reduction across the foundation-living space floor assembly. It is aimed at reducing radon levels in the lowest living level of the house.  Basements used as a living level are not candidates for this study.

As a part of this study, we are currently seeking homes in Champaign County with crawlspaces or unfinished basements. During this 3 month project, radon concentrations are measured before and after treatment, which involves air-sealing on the underside of the floor and duct sealing. There is no cost to the homeowner. Homes with known radon issues are preferred but not required. Please contact Stacy Gloss at or 217-300-7430 for more information.

We will not be conducting radon education. More information about radon can be found on the Illinois Emergency Management Agency (IEMA) website or by calling IEMA in Springfield at (217) 782-2700, as well as on the U.S. EPA's radon website. The U.S. EPA also maintains a Citizen's Guide to Radon and has a page regarding healthy indoor environments when implementing energy efficiency upgrades.

This is not a health study. We will not be collecting health information.
