RADIOACTIVE POCKETS IN THE SOUTHERN SEASHORE OF KERALA, INDIA

Lekshmi. R, P. J. Jojo

Abstract :

 There are quite a few identified monazite sand–beå placer deposits causing environmental high radiation area along its long coastline of Kerala and Tamil Nadu in India. The extent and effects of the radioactivity in the regions like Chavara and Neendakara in Kollam, Kerala is well known. Following a pilot study along the southern west coast of Kerala state, India we found certain regions with higher levels of natural radioactivity and hence made a detailed investigations of ambient gamma levels in those locations namely Perumathura, Kovalam and Varkala. Estimation of external gamma dose levels based on soil spectrometry was carried out. The results show that more than 90% of samples have higher specific activities for 238U and 232Th  in the soil collected from the region with a mean absorbed dose rate of 176±73 nGyh–1 in Perumathura, 161±29 nGyh–1 in Kovalam and 197±162 nGyh–1 in Varkala.
