N2 - The paper discusses the results of 30 years of radon indoor entry research. While some progress has been made, many discrepancies between current theories and experimental data still remain. Misconceptions of radon transport mechanisms in homes are analyzed. The role of US Environmental Protection Agency in radon indoor entry research is examined and the agency's policies are criticized. The need to include thermotranspiration gas transport in the general model of radon indoor entry is substantiated. Iran. J. Radiat. Res., 2008 6 (1): 1-6 M3 ER -
