Exposure to Radon gas through inhalation can cause radiological risk. This study was carryout to ascertain the possibilities of radon gas pollution due to the inhalation of radon gas in the study area and to compare its concentration in houses built on rocks and those that are not built on rocks. The radon activity concentration were determined in some selected residents in Barkin-Ladi and environs in Barkin-Ladi Local Government Area of Plateau State where most residents were built on rocks. The concentration of 222Rn was determined using Safety siren pro radon gas detector. The result show that the activity concentrations of 222Rn for houses built on rock ranges from 173Bq/m3-222Bq/m3 and for houses not built on rock, the 222Rn activity concentration ranges from 177Bq/m3-218Bq/m3. The values obtained when compared with the world average was found to be below the allowed limits in some communities and above the allowed limits in some of the communities. Therefore living in those communities where the radon activity concentration does not exceed the allowed limit in studied area will pose no significant radiological hazards to the residents. However, dwelling in the communities where the radon activity concentration exceeds the allowed limit in the studied area may pose slight radiological hazard to the residents.
