Radon in the Environment of Industrially Polluted Cities in Haryana

Measurements of radon are important because the radiation dose to human population due to inhalation of radon and its progeny contribute more than 50% of the total dose from natural sources. In the present study radon monitoring has been carried out in the two industrially polluted cities of Haryana using alpha sensitive LR-115 type II solid-state nuclear track detectors. The potential alpha energy concentration (PAEC), radon levels (EEC), annual exposure, annual effective dose varied from 4.98 mWL to 20.54 mWL, 46.1 Bq m-3 to 190.3 Bq m-3, 0.20 WLM to 0.85 WLM and 0.79 mSv to 3.27 mSv in Panipat city and from 5.97 mWL to 21.17 mWL, 55.3 Bq m-3 to 195.8 Bq m-3, 0.25 WLM to 0.87 WLM and 0.95 mSv to 3.37 mSv in Faridabad city. The geometrical mean of overall annual inhalation dose in the Panipat city it was 1.61 ± 0.05 mSv, and in the Faridabad city, it was 1.94 ± 0.05 mSv.
