title: Verifying a model of radon decay product behavior indoors.
abstract: Where it is not feasible to reduce radon levels in houses, exposure to radon decay products may still be reduced through air filtration or other air treatment techniques. A model which accurately describes the behavior of decay products indoors would be helpful to development or improvement of such air treatment techniques. We use a minor modification of a well-known model to describe the behavior and fate of radon decay products in the average indoor environment, and examine the adequacy of the model to predict the impact of a variety of air treatment techniques on indoor radon decay product levels. We find that the indoor environment is successfully described by the model and that plate-out of radon decay products on surfaces is much less than previous work has suggested. We also find that the model provides a plausible explanation of the effectiveness of a variety of techniques that remove radon decay products from the air.
