A review on distribution coefficient (Kd) of some selected radionuclides in soil/sediment over the last three decades

This review paper presents the different methods to estimate K-d and subsequent compiles of the K-d data on U, Ra, Th, Cs-137 and Co-60 in soil/sediment under various aquatic medium based on the extensive literature survey over the last 3-decades (1990-2019). The estimated K-d values show a very wide range and make more difficult to derive generic value. The finding suggests that K-d values are to be estimated for site-specific conditions while assessing the radionuclide transport modeling and risk analysis around the nuclear facilities. Review includes research papers, reports, reviewed papers, dissertations, published compilations and other technical documents.
