Assessment of health safety from ingestion of natural radionuclides in seafoods from a tropical coast, India
2011
Khan, M Feroz | Godwin Wesley, S.
The activities of ²¹⁰Po and ²¹⁰Pb were determined in commonly consumed seafoods to evaluate the internal exposure and risk to humans residing Kudankulam coast where a mega nuclear power plant is under construction. The concentration of ²¹⁰Po in seafoods ranged from 1.2±0.7 to 248±8.1Bqkg⁻¹. Meanwhile, ²¹⁰Pb ranged between 1.1±0.05 and 14.8±1.6Bqkg⁻¹. The committed effective dose (CED) due to ²¹⁰Po and ²¹⁰Pb varied from 11.04 to 515.6 and 3.93 to 23.5μSvyr⁻¹, respectively. The lifetime cancer risk for the public due to ²¹⁰Po was in the range of 3.47×10⁻⁵–1.62×10⁻³ and it was 4.03×10⁻⁵–1.96×10⁻⁴ due to ²¹⁰Pb. The activity intake, effective dose and cancer risk was found lesser than international guidelines and the seafood intake was considered to be safe for human consumption.
