Abstract:
Measurements of the effective dose through inhalation from radon and its progeny are important for human health since they contribute more than 50% of the total radiation dose from natural sources.In consequence of this radon has been identified as second leading cause of lung cancer after smoking. In the present study radon monitoring has been carried out in some typical Indian dwellings made from a variety of materials, including fly ash bricks, fired mud bricks, stones, concrete blocks and mud, using alpha sensitive LR-115 type II solid-state nuclear track detectors. The potential alpha energy concentration, radon concentration, annual exposure, effective dose and lifetime fatality risk in the fly ash brick dwellings varies from 9.34mWL to 21.24mWL with an average of 13.11 ± 0.63mWL; 86.48Bq·m -3 to 196.66Bq·m -3 with an average of 122.42 ± 6.16Bq·m -3 ; 0.385WLM to 0.875WLM with an average of 0.54 ± 0.026WLM; 1.49mSv to 3.38mSv with an average of 2.09 ± 0.10mSv and 1.15 ± 10 -4 to 2.62 ± 10 -4 with an average of (1.62 ± 0.08) ± 10 -4 , respectively. The effect of whitewash, plaster and paint on the emanation of radon from building materials used in construction of houses has also been studied.
