Novel method to reduce indoor radon level
Аннотация. The results of our recent radon indoor prevention research have been presented. Radon gas mitigation in human dwellings is known to be necessary to achieve an overall environmental risk reduction. We have synthesized a new nanostructured composite for the surface treatment of walls, floor, ceiling, roof, etc. to seal entry routes and reduce radon exposure inside dwellings. The silicon-nanoparticle-based organic composite contains the combination of polyethylhydrosiloxane and the solution of alkyltriethoxysilane in isopropanol with a tin-based catalyst. The nanostructured composite can fill very fine pores inside the concrete/cement/gypsum not only from radon, but also from VOC (volatile organic compounds), different organic and inorganic gases. The technique helps reducing gas permeability in several hundreds times. It was demonstrated that the consumption of our silicon-nanoparticle-based composite depends on the porosity of the material to be treated.
Ключевые слова: radon, nanocomposite, polyethylhydrosiloxane, VOC.
