Research on Electrostatic-filtration Radon Elimination Techniques in Underground Space

摘要

Radon and its progeny, lung carcinogens recognized by International Agency for Research on Cancer (IARC) and World Health Organization (WHO), are often obtained to high concentrations in underground space. Based on its decay law, radon and its progeny with bound and unbound state will cause serious damage on health. At present, several common mitigation methods had been taken to eliminate Rn in the indoor air. However, the environment of underground space often limits the effect of these facilities. Both electrostatic field and filtration are mature technologies in the field of atmosphere purification. Combined with these two different technologies, the electrostatic-filtration radon progeny eliminator is an effective equipment which can eliminate radon and its progeny indirectly. The method is an effective complement to the construction anti-radon technology and ventilation radon elimination technology, and also it is an essential way to solve the problem of radon damage in the underground space.
