| Abstract: |
Measurement of indoor radon and its progeny levels was
carried out in some typical dwellings made up of baked mud bricks, fly ash
bricks, concrete blocks and mud houses using LR-115, Type II plastic track
detectors in various districts of Haryana. The Potential Alpha Energy
Concentration (PAEC) varied from 4.36 to14.53 mWL; Equilibrium Equivalent
Concentration (EEC) of radon varied from 40.33 to 134.40 Bq m-3;
annual exposure varied from 0.18 to 0.60 WLM; annual effective dose varied from
0.69 to 2.31 mSv and life-time fatality risk varied from 0.54  10-4
to 1.8 10-4
in the environment of dwellings in various districts of Haryana. The
effect of various parameters on radon concentration such as seasonal variation
and type of building materials was also studied. The radon concentration in
industrially polluted cities like Faridabad,
Panipat, Rewari, Yamun Nagar was found to be more. The measured radon and its
progeny levels were the highest in winter season. In the measurements, we found
that radon concentration was the maximum in fly ash houses.
