Study of 222Rn concentrations in some dwellings of Rajasthan.
Total potential alpha energy concentrations due to radon progeny were measured in 143 dwellings of Udaipur, Bikaner, and Banswara towns of Rajasthan province of India with LR-115 type II detectors.
The geometric mean values of total potential alpha energy concentrations in these three towns were found to be 1.9 x 10-7 J m-3,1.2 x 10-7 J m-3 and 1.7 x 10-7 J m-3 with a geometric standard deviation of 2.2,2.2, and 2.5, respectively.
The estimated lifetime risk of lung cancer due to indoor radon exposure for a total population of study area was estimated to be 6.7 x 10-3 or 0.67%. The mean relative loss of life expectancies were 0.20%, 0.12%, and 0.18%, respectively.
