The purpose of this study was to evaluate selected coatings as radon barriers in uranium mines;first on their effectiveness in reducing radon permeation, and second on the basis of their potential toxicity during application or in a possible mine fire. Hopefully, this information would be helpful in developing coatings more effective than those commercially available.nThe program was organized in three tasks:(1) Film Selection and Preparation;(2) Measurement of Permeability;and (3) Evaluation of Toxicity of Coatings.
