Abstract
The present investigation involves the distribution of 210Po in the soils of Virajpet taluk, in Coorg District. The soil samples were collected along a vertical profile at various locations. The samples were analyzed for determination of 210Po activity using standard radiochemical analytical method. The distribution of 210Po along vertical profile was found. The dependence of 210Po activity on organic matter and clay in a vertical profile were analysed. The texture of soil shows that soil is sandy loam or loamy sand, in which illuviation takes place easily. The 210Po activity varies from 1.59 Bqkgâ1 to 13.95 Bqkgâ1 in first layer, 0.49 Bqkgâ1 to 9.79 Bqkgâ1 in second layer and 0.58 Bqkgâ1 to 6.14 Bqkgâ1 in third layer. A negative correlation between organic matter percentage and 210Po activity was found in all the three layers with correlation coefficient â0.872, â0.643 and â0.505. A negative correlation was observed between clay percentage and 210Po activity, in all the three layers with correlation coefficient â0.749, â0.512 and â0.402. The organic matter leaches vertically downwards, due to flow of rainwater.
