*Geological investigation of Natural Background Radiation Hazard in
Southern Tamil Nadu, India, and its effect on built environment*
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.
