摘要：
The 226Ra, 232Th and 40K activities were investigated in soil samples of Chikkamagaluru district, Karnataka, using γ-ray spectrometry. The average activity of 226Ra, 232Th and 40K were found to vary from 15.2 ± 0.6 to 58 ± 1.2 Bq kg−1, 14 ± 0.6 to 86.2 ± 1.7 Bq kg−1, and 224.5 ± 5.5 to 1650 ± 20.3 Bq kg−1 with a mean value of 36.93 ± 1.0, 51.6 ± 1.3 and 566.97 ± 11.0 Bq kg−1. The average activity concentrations are slightly higher than world average value. The average annual effective dose is more than the Indian average value of 0.084 mSv y−1. The average values of all the radiological hazards are less than the criterion limit.
