In this study, radon (Rn) measurements were evaluated for the first time in the underground metro and Marmaray stations in Istanbul and the annual effective dose values were calculated to the employees and for passengers. Radon concentrations ranged from 39.47 to 382.02 Bq m(-3) for the railway platforms. The average radon value for all station platforms found to be 114.60 Bq m(-3). The annual effective dose values for the employees working at the platforms varied from 0.12 and 2.75 mSv y(-1), while the data for the passengers were varied from 0.035 and 0.34 mSv y(-1).
