It consisted of several radionuclides viz., 131I, 137Cs, 134Cs, 132Te, 132I, 136Cs, etc., as well as radioactive noble gases (133Xe and 135Xe). A large area was contaminated mainly due to deposition of radio Cs isotopes. Environmental monitoring with respect to different radionuclides is important to understand the cause of accident [2]. Most of the nuclear fission radionuclides are carcinogenic in nature whereas some are hazardous to biotic system. From the viewpoint of radiological safety in a living environment, radionuclides e.g. 137Cs, 90Sr with long half lives (t1/2~30y) are of major concern due to solubility in aqueous solution under normal condition. Hence the investigation of sorption behaviour of sorbed radionuclides plays an important role to predict transport and diffusion in soil-water system [3].\n\n Sorption includes various processes by which dissolved radionuclide ion can bind to solid surfaces. For sorption assisted diffusion processes, Kd (Distribution Coefficient by batch method) is one of the important parameters for the measurement of migration of radionuclides in the soil column during any nuclear accident.\n\nIn the present work, sorption behaviour of Cs, Sr and U has been examined by quantification of solid-liquid distribution coefficients (Kd) using batch method in soil samples contaminated due to FDNPP accident. To establish the fate and transfer of radionuclides, site specific distribution coefficient (Kd) were measured in the soil samples using standard method. Log Kd values for Cs, Sr and U were found to be ~1, 2 and 3 respectively. Different soil parameters like particle size distribution, pH, organic content, cation exchange capacity (CEC), CaCO3, elemental and oxide composition of soil has been carried out to understand the geochemical behaviour of these radionuclides. The characteristics of Kd will be discussed in detail during presentation.
