长沙市地下车库氡污染的现状及对策研究

Research on Radon Pollution Situation and Strategies of Underground Garages in Changsha

氡及其子体污染是地下建筑内部空气质量中一个不可忽视的问题。本文通过对长沙市不同场所地下车库空气中氡浓度水平的测量与分析,总结出了长沙市地下车库空气中氡污染的现状及规律特点,认为地下车库空气中氡浓度与地下车库的通风情况关系密切,并在此基础上提出了降低地下车库氡含量的意见和措施。

The pollution of radon and its progeny is a prominent problem in the air environment of underground buildings. This paper measures and analyses radon concentration level in different kinds of underground garages in Changsha, and summarizes the present situation and regularity of radon pollution in them. We believe that radon concentration level in any underground garage is closely related to its ventilation condition, and base on this we put forward suggestions and measures for reducing radon concentration level in underground garages.
