摘要：

The activity concentrations of U-238, Th-232, and K-40 were determined at 56 sites along the East Coast of India, near the Bay of Bengal, with 31 sites in Odisha and 25 in Andhra Pradesh. In Odisha, average concentrations were 109 +/- 13 Bq kg(-1) for U-238, 296 +/- 27 Bq kg(-1) for Th-232, and 450 +/- 33 Bq kg(-1) for K-40, while in Andhra Pradesh, they were 51 +/- 13 Bq kg(-1), 149 +/- 16 Bq kg(-1), and 236 +/- 21 Bq kg(-1), respectively. Absorbed dose rates and annual effective doses were higher outdoors and indoors in Odisha compared to Andhra Pradesh. The calculated radiological parameters exhibited elevated values at certain sampling locations; however, overall, the values generally complied with regulatory standards.
