COMPARATIVE-STUDIES OF POLYMER MATERIALS AS RADON PROTECTION COATING

The control of indoor radon levels has become a public health issue (E spinosa et al. 1991; Hakl et al. 1991). New regulations and architectu ral designs are being developed for residential areas, homes and publi c buildings. Radon concentration is directly related to the ratio betw een energy conservation and open-window ventilation. A large percentag e of the accumulated radon comes via its infiltration through walls an d floors (Cohtern et al, 1987). Some possible solutions to the problem involve: 1) The use of thermally-insulated boards which still allow t he passage of radon to the outside; and 2) the use of coatings to redu ce the infiltration through the wall and floors.
