“…The water was then compactly packed in 500 ml high quality polythene bottles, sealed and kept undisturbed for 1 month (for the daughter radionuclides of the U-Th series) for the determination of 40 K, 238 U, 208 Tl ( 232 Th), and 226 Ra. 137 Cs was pre-concentrated with ammonium molybdophosphate (AMP) from 30 l of seawater [6]. The samples were subjected to low-level hyper pure germanium gamma spectrometry (HpGe) for 50, 000 s. On the other hand, 210 Po in seawater was determined by pre-concentration using Fe(OH) 3 followed by silver plating [7].…”

Abstract. Concentrations of natural radionuclides 238 U, 208 Tl ( 232 Th), 226 Ra, 210 Po, 210 Pb and 40 K, and fallout 137 Cs were determined in pelagic and demersal fishes which are of economic importance. Pelagic fishes concentrated more radionuclides in the muscle tissue when compared to benthic species. Similarly, teleosts registered more activity than elasmobranchs. Based on the activity levels in muscle, the intake, effective dose and lifetime risks to humans were estimated. The internal radiation doses received by fishes and human beings seem to be mainly due to 210 Po and 40 K. The fishes were found to be safe for consumption.

The globally distributed fallout radionuclide (137)Cs was monitored in 25 resident and 22 migratory fish species collected from some regions of west and east coast of southern India to establish a baseline data. The samples were collected during June 2008 to June 2009. Higher level of (137)Cs was noted in planktivorous fishes and lower level in herbivores. A significant variation in (137)Cs was observed between fishes with different feeding habits and different migratory pattern. Oceanodromic migratory fishes displayed higher cesium levels than other migratory types. Similarly, migratory fishes displayed higher (137)Cs concentration compared to resident fishes. The overall range of (137)Cs varied from 0.06 to 0.3 Bq/kg in fishes. The biological concentration varied from 55 to 250. The average external dose rate to fishes was calculated to be 2.7 × 10(-7) μGy/h, while the internal dose rate varied from 8.50 × 10(-6) to 5.27 × 10(-5) μGy/h. The hazard quotient for fishes was found to be less than 1. The average intake of (137)Cs via fishes to the public was calculated to be 3.5 Bq/year and subsequently the committed effective dose was 0.05 μSv/year. The data obtained were less than global average and comparable to those of many regions.
