Research on a Radon Proof Hydrous Paint

Radon and radon proton may be extensively found in houses and buildings. Radon is radioactive in air and pernicious to health. The use of pure rhoplex and superfine SiO2 can produce a kind of paint to protect against radon. This paper put forward the basic formula of the paint. According to experiments in the laboratory and houses, the elimination rate for radon could attain 86.16% and 67%, respectively. A radon proof hydrous paint could well avoid the perniciousness of radon. The results of experiment and the mechanism are discussed in this paper.
