The present study focuses on internal exposure caused by the inhalation of radon and thoron progenies because the internal exposures have not yet been clarified. For their dose assessment, radon, thoron and thoron progeny concentrations were measured by passive monitors over a long period (for 6 months). Consequently, radon, thoron and equilibrium equivalent thoron concentrations were given as 124 +/- 78, 1247 +/- 1189 and 7.8 +/- 9.1 Bq m(-3), respectively. Annual effective doses are estimated to be 3.1 +/- 2.0 mSv for radon and 2.2 +/- 2.5 mSv for thoron. Total dose are estimated to be 5.3 +/- 3.5 mSv a(-1). The present study has revealed that the radon dose was comparable with the thoron dose, and the total dose was similar to 2 times higher than the worldwide average.
