A radon survey was carried out in the soil gas and indoor air of dwellings near the selected sites known for uranium occurrence using both Alpha-Guard (active) and track-etch (passive) techniques. Alpha-Guard is a pulse ionisation chamber and the passive technique utilises a cellulose nitrate plastic detector, LR-115 type II. Radon concentration in the soil gas was found to vary from 1020±270 Bq/m 3 (Mehre) to 75.4±2.62 kBq/m 3 (Samurkhurd) using the Alpha-Guard spot survey. Indoor radon levels for the Ramera and Asthota Villages measured by Alpha-Guard spot-checking showed a large variation from house to house and from the summer to winter season. Integrated track-etch radon values were measured from August 1997 to December 1997, and the arithmetic mean values for the Ramera and Asthota Villages were found to be 165±9 Bq/m 3 and 145±12 Bq/m 3, respectively. The average exposure doses due to radon to the inhabitants in these villages amounted to 2.8±0.2 mSv and 2.5±0.2 mSv, respectively, which are lower than 10 mSv, the annual effective dose fixed for a remedial action plan in the dwellings, according to international recommendations.
