Abstract
The effective dose of the Seoul subway staffs due to inhaled radon ($^{222}Rn$) in their workplace was investigated depended on radon concentration exposed at each workplace, and working hours and working types of the staffs. Annual average radon concentrations ranged from 16.5 to 93.0 $Bq{\cdot}m^{-3}$. The staffs commonly spend 2,304 hours in the underground spaces a year. With the radon concentrations and the working hours of the staffs, estimated annual effective doses ranged from 0.23 to 0.73 $mSv{\cdot}y^{-1}$.
