Abstract
Indoor air and soil gas radon measurements are simultaneously performed in Hamirpur district of Himachal Pradesh using RAD7, a solid state alpha detector. The study is performed for the estimation of radon level and annual effective dose for indoor air. Different locations are selected and it is found that the variation of radon concentration in indoor air and soil gas in Hamirpur region ranges from 35Bqm−3 to 956Bqm−3 and 35 to 2280Bqm−3 having mean values 189.43Bqm−3 and 462.56Bqm−3 respectively. From indoor air, the total annual effective dose is calculated and it varies from 0.88mSvy−1 to 24.09mSvy−1 with mean value of 4.77mSvy−1. In general, it is found that the annual effective dose limit was within the recommended reference level (3mSvy−1to 10mSvy−1) of the world organisations. A good correlation between radon concentration in air and soil gas is observed.
