Measurements in a full-scale experimental facility are used to benchmark a semiempirical model for predicting indoor radon concentrations for Florida-style houses built using slab-on-grade construction. The model is developed to provide time-averaged indoor radon concentrations from quantitative relationships between the time-dependent radon entry and elimination mechanisms that have been demonstrated to be important for this style of residential construction. The model successfully predicts indoor radon concentrations in the research structure for several pressure and ventilation conditions. Parametric studies using the model illustrate how different ventilation strategies affect indoor radon concentrations. It is demonstrated that increasing house ventilation rates by increasing the effective leakage area of the house shell does not reduce indoor radon concentrations as effectively as increasing house ventilation rates by controlled duct ventilation associated with the heating, ventilating, and air conditioning system. The latter strategy provides the potential to minimize indoor radon concentrations while providing positive control over the quality of infiltration air.
在一个全尺寸实验设施中进行的测量，用于对一个半经验模型进行基准测试，该模型用于预测采用地面平板式建筑的佛罗里达风格房屋的室内氡浓度。开发该模型是为了根据随时间变化的氡进入和消除机制之间的定量关系，提供时间平均的室内氡浓度，这些机制已被证明对这种住宅建筑风格很重要。该模型成功地预测了研究结构在几种压力和通风条件下的室内氡浓度。使用该模型进行的参数研究说明了不同的通风策略如何影响室内氡浓度。结果表明，通过增加房屋外壳的有效泄漏面积来提高房屋通风率，并不像通过与供暖、通风和空调系统相关的受控管道通风来提高房屋通风率那样有效地降低室内氡浓度。后一种策略有可能在对渗透空气质量进行积极控制的同时，将室内氡浓度降至最低。
