Radon concentration for the summer seasons of 2020 was measured in 12 buildings of Karabük University / Karabük governorate / Turkey using the passive technique. Solid state nuclear track detectors (CR-39) were used for calculating the track of alpha particles emitted from the decay of radon. The results of 222Rn concentration for ground and underground showed that the lowest value was 8.547 Bq/m3 in Literature Faculty (LF) building, and the highest value was 83.498 Bq/m3 in Foreign Language High School (LHS) building. All radon concentrations are within the acceptable concentrations for natural exposure by International Committee of Radiation Protection [ICRP, 2009]. Annual effective dose (AED), lung cancer cases per year per million person (CPPP), potential alpha energy concentration (PAEC), the dose rate for soft tissues, the dose rate for the lungs and the effective dose equivalent rate have a range of 0.216 - 2.107 mSv/y, 0.634x10-2 - 6.19x10-2 per million person, 1.04 - 10.155 mWL, 0.043 - 0.417 nGy/h, 0.342 - 3.340 nGy/h and 1.538 - 15.030 nGy/h respectively, which are all below the recommended limits by the international agencies [UNSCEAR & ICRP]. © 2023 Author(s).
