Distribution of 226Ra, 210Pb and 210Po in soil of a uranium mineralised region of Northern Karnataka, India
摘要
The activity concentrations of 226Ra, 210Pb, and 210Po in soil samples were measured in the Gogi region of Yadgiri district, Karnataka, South India, which is a uranium mineralisation area with prospects for future mining. A total of 273 samples were analysed from 0–5, 5–15, and 15–30 km zones around Gogi, the common centre of all the zones. The activity concentrations of these radionuclides were similar to the global average values. A strong positive correlation was found between the activity concentration values of 226Ra, 210Pb and 210Po. Negative correlations were found between the activity concentrations of these radionuclides and soil characteristics such as cation exchange capacity (CEC), organic matter content (OMC), and pH.
