Radon reduction through floor air sealing

Research output: Contribution to conferencePaper

Abstract

A pilot study was done on five homes to evaluate the impact that air sealing between the first floor and foundation space has on radon levels. Air sealing was done around floor penetrations and on forced-air ductwork. Treatments were staggered so that homes that were not treated acted as controls for homes that were treated, in an effort to adjust for radon variations resulting from changing environmental conditions. The results did not show any statistically significant changes in radon levels resulting from air sealing. The radon data showed that correlations between living space and foundation space levels were poor, and correlations between different homes were poorer. This means that the small sample size was insufficient to successfully control for weather conditions. The data also showed that radon levels increased with increasing outdoor temperature, which is counter to expectations from temperature-difference-based driving forces.
