Measurement of indoor radon concentration in district Mardan, Khyber Pakhtunkhwa, Pakistan

Abstract

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.
