The activity concentration of Ra-226, Th-232 and K-40 was measured for soil samples collected from 34 locations of Tumkur District, Karnataka, India, using HPGe detector. The activity concentration of Ra-226, Th-232 and K-40 varied from 9.6 to 71.6, 12.3 to 333.3 and 194.3 to 1527.7 Bq kg(1) with an average value of 33.15, 123.01 and 877.76 Bq kg(1), respectively. The absorbed and annual effective outdoor doses were found to be highest at Ponnasamudra with 258.98 nGy h(1) and 317.62 Sv and lowest at Sira with 36.42 nGy h(1) and 44.67 Sv, respectively. The external hazard index ranged from 0.21 to 1.58 with an average of 0.75. It was significant in 11 locations as it exceeded unity.
