Reduction of the radon entry rate from building materials by industrial surface coatings
article
The retaining effect of over 20 different surface coatings on the free 222Rn exhalation rate has been studied. Coatings that are normally applied for decoration of walls and ceilings in homes were found to be ineffective. Reductions of up to 75% were found for other coatings studied, when applied to all sides of the test walls. If the surface coating is applied to only one side of the wall, coatings on the basis of epoxy resin and polyurethane could reduce the exhalation rate by 95%, according to model calculations. Chemicals/CAS: polyurethan, 61789-63-7; radon 222, 14859-67-7
