Abstract: Exposure and quantification of radioactivity has become
environmental and civil problems around the world. The
radioactivity even in minor quantities will build up in human body
and subsequently, lead to unknown and erratic health complications
particularly those related to sustainable development,
agricultural production, habitat, ecosystem, and forest. A very
high intrinsic anomalous radioactivity >26 microGy/h was
identified in the hinterlands within the boulders of syenite rock
body around Puttetti in western part of Kanyakumari district,
southern Tamil Nadu, India. Further, in the hinterlands, the
weathered rocks around Inayam and Midalam localities were also
found to be more radioactive ranging from 4 to 22 microGy/h
compared to the radiation exposure from the adjoining beach
sectors at various locations from Chavara to Tuticorin (1–14
microGy/h). The observed radiation levels are presumably the
highest concentration in southern India and conceivably it is
foremost instant that a very high intrinsic radiogenic source in
the hinterlands is reported in southwest coast of India. Public
concerns of radiation exposure of safety in high background areas
are of great social and civil relevance. The construction
materials used for dwelling purposes from these areas should be
avoided from health hazard point of views. Significant radiation
doses will certainly enter the human body as most of the people
have the habit of sitting and sleeping on the floor. People living
in the region are expected to receive significant radiation, which
may get accumulated in the human body causing long-term health
problem. It is also advisable if the area falls having already
natural background radiation hazard must be avoided for the future
nuclear power plants/reactors.</div>
