A review on the dynamics of natural radionuclides along the coastal environs of Kerala, south west coast of India

Extensive and systematic investigations have been carried in almost all parts of the world in order to obtain a clear understanding of basic dynamics of radionuclides in the environment. In this context, this review is an attempt to probe the environment of coastal Kerala by consolidating the major studies carried out on environmental radioactivity mostly employing well-established nuclear techniques and radiochemical methods.The review indicated the need for more in depth and focused studies in this sector to confirm the sources of monazite bearing black sands and the geological factors influencing their formations. The consolidation will be scientific assessment for the future, the impact of assessment of major and minor industrial activities and other human interventions in the environment of coastal Kerala.
