Presence of uranium series radio nuclides particularly 226Ra in construction material is potential source of release of radon in the dwellings. Inhalation dose received by residents due to radon & radon progeny depends on geological strata beneath, nature of the construction material and the ventilation status of the house. Apart from the uranium mineralization uranium mining and ore handling activities may affect the inhalation dose contribution to public due to radon and its progeny. Present investigation pertaining to the assessment of indoor inhalation dose was carried out for population residing in the dwellings around UCIL complex at Narwapahar. Seasonal variation in indoor radon concentration profile of different type of residential quarters /dwellings near to the uranium mining areas was evaluated using SSNTD based integrated radon measurement technique. Results reveal that annual average indoor radon activity concentrations in studied dwellings varies from 77 – 172 Bq.m-3 with geometric mean of 73 Bq.m-3 GSD of 2.4. The corresponding annual inhalation dose varies from 1.14 to 2.05 mSv with estimated mean dose of 1.08 mSv.y-1 based on the geometric mean concentration of radon in dwellings.
