Soil samples were collected from Hassan district of South India. The analysis was carried out using NaI (Tl) gamma ray spectrometer. The 232Th activity was found to vary from 20.4 ± 1.3 Bq/kg to 136.3 ± 3.3 Bq/kg with a mean value of 56.9 ± 2.0 Bq/kg, and 226Ra activity was found to vary from 22.5 ± 1.4 Bq/kg to 90.6 ± 3.4 Bq/kg with a mean value of 41.4 ± 2.1 Bq/kg. The activity of 40K was ranged from 278.2 ± 4.0 Bq/kg to 650.7 ± 6.7 Bq/kg with a mean value of 388.4 ± 5.1 Bq/kg. Relatively higher levels of thorium were observed in soil. The radium equivalent activity and other radiological parameters were also determined.
