Polymer cement plaster to prevent radon gas contamination within concrete building structures

This paper describes an e3ective method to reduce radon concentrations emitted from concrete materials within the interiors of buildings. Promising results have also been obtained from an on-site test to a 600 ft2 residential 5at using alpha track detectors, where the radon concentration has been reduced by 90% on average. This new material provides a good shielding e3ect against di3usion of radon gas that reduces radiation pollution.
