Abstract
Radon and radon decay-product concentrations were measured weekly for a period of 1 year in 20 homes. A seasonal cycle was observed for the radon concentrations, with a low during the warmer months and a high during the cooler months of the year. Radon decay-product concentrations were found to generally follow the radon cycle, as expected. The equilibrium ratio was observed, however, to vary inversely with the radon and radon-decay product cycles. The indoor radon cycle for the 20 homes was also found to follow the inverse of the outdoor radon concentrations. Some speculation and supporting data are presented to explain the inverse indoor and outdoor relationships.
