Distribution of Po-210 and Pb-210 radionuclides and their dependence on physico-chemical parameters of soil in Madikeri taluk, Coorg district, Karnataka, India

摘要

The paper deals with distribution of Po-210 and Pb-210 radionuclides in a vertical profile of illuviated soil, in Madikeri taluk of Coorg district, Karnataka, India. The activity concentration of Po-210 and Pb-210 radionuclides was determined using radioanalytical method and the dependence of these radionuclides on physico-chemical parameters of soil was also investigated through a statistical study. In all the layers of the soil in a vertical profile, the Po-210 nuclides were found to be in disequilibrium with Pb-210. The frequency distribution of Po-210 and Pb-210 radionuclides was analysed using Kolgomorov-Smirnov test.
