Rock sealant restricts falling barometer effect.
Min Eng 1977 Dec; 29(12):38-39
Data collected during a 1973 test of radon barrier coatings at Grants, New Mexico, was analyzed to reevaluate the coating's effectiveness for stopping radon gas in a uranium mine. The comments in the literature indicated that pinholes in the coating would seriously limit the coating's beneficial properties. Analysis of results showed that the average radon concentration was reduced 70 percent by the application of the coating, and that the coating also reduced the effect of changing barometer on the radon emanation by a factor of about 5.
