Studies on distribution of ²¹⁰Pb in the illuviated soil of Virajpet taluk, Coorg district

The present investigation deals with the distribution of ²¹⁰Pb radionuclides and their dependence on various physico-chemical parameters of soil, in Virajpet taluk, Coorg District. The samples were analyzed using standard radioanalytical methods for the determination of ²¹⁰Pb activity. The ²¹⁰Pb activity varies from 3.59 Bq kg^-1 to 44.63 Bq kg^-1 in the first layer, 0.79 Bq kg^-1 to 22.86 Bq kg^-1 in the second layer and 0.88 Bq kg^-1 to 16.34 Bq kg^-1 in the third layer. A negative correlation was found between ²¹⁰Pb activity and clay% and also with organic matter%, in all three layers. (author)
