ABSTRACT

Indoor environments contribute to gamma radiation in the general population. The aims of the present study were to investigate average gamma radiation doses in the indoor dwellings. Also to compare indoor dose measured with personal exposure. Hence accumulated indoor gamma dose were evaluated around a prospective Uranium mining area of Gogi village, Yadgir district, North Karnataka, India. A passive measurement technique was adopted for the measurement of dose in the present study i.e. using thermoluminescent dosimeter (TLD). Also an active measurement was carried out in order to compare with the passive results using RadEye personal radiation dosimeter. The dwellings selected are at a 5 km radius from the Uranium mining area. A TLD is employed in the dwelling at about 2m above the ground level and 30cm away from any wall or surface. A total of 100 dwellings were selected for the study during the month January to April, 2013. The average annual effective dose estimated for TLD in Gogi region was found to be 0.69 mSv y-1and 0.49 mSv y-1for RadEye survey meter. The dose rate is higher for RCC than other type of dwellings.
