Abstract: In this study we measured radon (²²²Rn) concentrations in offices at the Meşelik campus of Eskişehir Osmangazi University to estimate the effective dose of ²²²Rn and its progeny for office occupants. The measurements were performed four times in 2011 over a period of 3 months using solid state nuclear track detectors (LR-115). A total of 381 LR-115 detectors were installed in 110 different offices, choosing three offices on each floor in the same building. ²²²Rn concentrations obtained in the first, second, third, and fourth measurement periods were 163 (73) Bq m^-3, 77 (43) Bq m^-3, and 164 (70) Bq m^-3 respectively. The ²²²Rn concentrations and seasonal ²²²Rn variations in the offices were similar to those found in dwellings in Eskişehir. the total annual effective dose was estimated to be 3.398 mSv y^-1.
