Quality Assurance Technician Horizon RES NH LLC Concord, New Hampshire
Radon concentrations naturally fluctuate in the home and long term exposure is of particular concern. Since energy retrofits can reduce air exchange, there is interest in whether indoor pollutant concentrations, such as radon exposures could increase. Researchers tested radon in homes over 5 years through 15 weatherization program partners across 6 states in winter and summer conditions. The BARRIER and BEX research projects studied changes in average radon levels in relation to reduced air infiltration achieved by tightening homes. Partnering weatherization agencies tested radon levels for 2 weeks before and for 2 weeks after weatherization retrofit measures in 300 homes. Home radon risks and considerations for quality installations of precautionary measures will be discussed.
By attending this session, attendees will:
Summarize impacts of current weatherization practices on indoor radon levels based on field research
Identify retrofit measures in weatherization that may curb radon increases
Discuss considerations for quality installations of precautionary measures
