Beach rocks samples were collected from South East Coast of Tamilnadu, India. The mineralogical composition was determined using FT-IR and XRD. The natural radioactive measurements to detect radioactive elements were determined by gamma ray spectrometer. The multi-element analyses were carried out by INAA (Instrumental neutron activation analysis), with the standard Estuarine Sediment as reference material. The geochemical behavior of elements in the region is discussed. The occurrence of the radioactive and non-radioactive elements is discussed for their geological significance. The results were used to assess environmental toxicity of heavy metals and radiation hazard in the study area.
