Development of an Anti-radon Coating for Underground Engineering

Abstract

To satisfy the requirements of underground engineering applications, an anti-radon coating was developed by selecting suitable modified polymer emulsions, element materials, pigments, fillers, additives, etc. Experimental results on radon mitigation performance show that for a coating thickness of 2.0 mm, the radon mitigation efficiency reaches 95.1%. In addition, an anti-radon coating has a very low content of toxic substances and excellent water resistance and durability. Using the coating in an engineering application showed that the coating has the advantages of fast drying speed, no peculiar smell and excellent radon mitigation performance, where 2-3 coats produce good radon mitigation in damp and sealed underground engineering environments.

Indoor radon mitigation strategies: The Alto Minho region (Northern Portugal) practical case

“…The conclusion was drawn by achieving an optimized level of radiation protection, a degree of reduction in radon exposure risk and heating cost. On the other hand, Pan et al 66 developed an anti-radon coating for use in underground engineering applications. The coating was developed using modified polymer emulsions, element materials, pigments and additives.…”

Indoor Radon Testing, Effective Dose and Mitigation Measures in a Residential House of a Mining Area

“…Anti-radon coating (anti-radon paint/radon barrier coat) for interior walls, foundations and slab of basement is confirmed as good solution for sealing of seams, cracks and joints between the wall and floor as well as spaces between the wall and window; it is reported that two years after coating, radon mitigation efficiency was higher than 86% [59]. The combination of mitigation strategies seems to be more effective than a single measure [56].…”
