Radon activity measurements in slate mines in the aravali range in Haryana were carried out from radiation protection point of view of the occupational workers and general public. For the measurement, alpha sensitive LR-115 type II plastic track detectors (solid state nuclear track detectors) were used. Results of various measurements of the radon activity and inhalation dose received by the workers have been reported. The radon activity and the annual inhalation dose in the environment of various slate stone mines in Haryana varied from 21 Bq m-3 to 113 Bq m-3 with an average of 38.5 ± 5.8 Bq m-3 and 0.37 mSv to 1.94 mSv with an average of 0.66 ± 0.10 mSv respectively. Seasonal variation of radon activity has also been studied and reported.
Key words: Radon, inhalation dose, environment, mine, aravali range.
