Abstract
This project determined the effectiveness of using polymeric materials as radon barriers. Permeation coefficients were established with argon, krypton, and xenon, and the results extrapolated to radon. Numerous polymeric materials were then tested and found to be good barriers to radon. Seven of the best were selected to determine which would be safe for use in uranium mines. The uncured chemicals were analyzed by gas chromatograph/mass spectrography to determine the presence of toxic vapors. Then the cured materials were analyzed through pyrolysis for toxic components. Most materials proved safe except saran latex, which produced a significant amount of hcl. The tested materials were ranked for barrier capability and safety for underground use, but the chief discovery was that radon barrier capability was less important than cost, application ease, and safety.
