An energy efficient approach for radon management. Part II: Radon modeling and evaluation.

This paper reports on the experimental results using a standard room chamber to evaluate the impact of various parameters on indoor radon concentrations. The paper assesses the suitability of using pro-existing mathematical models for the prediction of indoor Volatile Organic Compounds (VOC) to estimate radon concentrations in the heating, ventilating and air conditioning (HV AC) environment. A test chamber study was conducted to thoroughly evaluate and validate parameters considered in these models. A modification factor to account for the indoor sinks was determined and was utilised to enhance the accuracy in applicability of the pre-existing models. The results indicates the modified radon prediction model is capable of correlating well with field data and appears to be applicable to other HV AC environments.
