“…Therefore, the radionuclides concentrations and distributions, and its associated dose rates in the beach sands from coastal environments should be monitored. The distribution of primordial radionuclides in coastal sands have been reported by many investigators [3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

The natural radioactivity content of 238U, 232Th and 40K in the intertidal beach sands samples at ten sites each of Marina and Besant Nagar beaches of Chennai city has been analyzed using a 3"x3" NaI(Tl) scintillation detector based gamma ray spectroscopy. The radioactivity content in intertidal sands of Marina were found to be 4±3 Bq.kg -1 , 4±3 Bq.kg -1 and 248±28 Bq.kg -1 respectively; the same were 4±3 Bq.kg -1 , 5±3 Bq.kg -1 and 242±29 Bq.kg -1 respectively in the beach sands of Besant Nagar. These activity levels at both beaches are, in general, much lower than other Indian and World average value. The radiological parameters for both the intertidal sand samples (Marina and Besant Nagar) are far lower than the UNSCEAR 2000 recommended values.

“…There are few regions in the world known to be high background radiation areas due to local geology and geo chemical effects that cause enhanced levels of terrestrial radiation [2]. In the high background areas of the country such as Austria, Brazil, China, France, India and Iran the radiation levels were found to be high varying over an order of magnitude depending upon the site-specific terrestrial radioactivity [3]. In India there are quite a few monazite sand bearing placer deposits causing high background radiation along its long coastal line.…”
