The study of the indoor radon concentration in district Mardan Khyber Pakhtunkhwa (KPK), Pakistan is presented. To know the impact of the dose for Mardan city, 40 CR-39 detectors were installed in different houses for a period of three months. The radon concentration for this phase of the year (early summer) is from 18.45 ± 0.53 to 41.51 ± 3.4 Bq/m3. The level of indoor radon concentration is the highest in the basements i.e. 41.51 ± 3.4 Bq/m3 which is within acceptable limit (148 Bq/m3), recommended by the Environmental Protection Agency. The annual effective dose calculated from this study is ERn = 0.704 mSv. It was concluded that indoor radon concentration may not suppose any severe threat to the health of residents.
