Potential health risk estimation of naturally occurring radionuclides intake due to the consumption of seafood around Coastal zone

As part of a regional baseline study, the distribution naturally occurring radioactive materials in marine fish diversity consumed by different age group representatives living Kalpakkam coastal zone was studied. The average activity natural radionuclide 238U, 232Th, and 40K (n = 40) 28.51, 239.58, 118.95 Bq kg-1, respectively. annual dose ingestion, lifetime carcinogenic risk assessment cancer due to were estimated children aged 1-4,5-9,10-14,15-17 years, adults, pregnant women, fishing community. Hospital-Based Cancer Registry (HBCR) compares zone. Statistical studies such as Pearson correlation analysis, Principle component Cluster analysis report check that current levels do not pose significant radioactivity threat residents based on radionuclide.
