Project Description: This study will determine if specific low-cost, simple weatherization activities reduce radon exposures and quantify any benefit regarding moisture. The work will be conducted by four local weatherization agencies in Illinois and New Hampshire (listed above). They will represent two different climate zones in areas with high radon levels. The objective is to evaluate 160 units in two study arms to determine the effectiveness of the low-cost measures.The first arm will include 80 homes undergoing weatherization with the low-cost enhanced sealing in basements and crawl spaces. The second arm will consist of two subgroups: one that undergoes retrofit without the enhanced sealing and another that will not have any retrofit during the course of the study. Houses will be randomly assigned to each group in each of two geographic regions known to have high radon levels. Preliminary results are expected in 2016.
