a systematic study on the concentration of 210Po and 210Pb in soil samples in and around Thirthahalli taluk has been carried out in 25 various locations. Standard sample collection procedure and radio chemical method has been employed in this study. The 210Po concentration was ranging from 4.8 ± 1.5 Bq/Kg to 41 ± 3.3 Bq/Kg and that of 210Pb lies between 5.9 ± 0.8 Bq/Kg to 71 ± 5.3 Bq/Kg. The 210Po to 210Pb ratio in this study is less than 1 indicating the presence of only supported 210Po in this region. All these results are presented in this paper.
