Abstract
Concentrations of radiocesium were determined in several fishes, shellfishes and macroalgae which are Korean favorite marine food sources. Samlpes were collected in Korean coastal and neighboring sea and the Pacific Ocean during 2011 - 2012. Target species included eleven species of fishes: mackerel (Scomber japonicas) anchovy (engraulis japonicus) hairtail (Trichiurus lepturus) roskfish (Sebastes schlegeli) walleye pollack (Theragra chalcogramma) bluefin tuna (Thunnus thynnus) yellowfin Tuna (Thunnus albacares) saury (Cololabis saira) stingray (Dasyatis akajei) flatfish (Paralichthys olivaceus) squid (Todarodes pacificus), one species of shellfish: oyster (Crassostrea gigas) and three species of macro algae: laver (Porphyra tenera) laminaria (Laminaria japonica) sea mustard (Undaria pinnatifida). The measured number per species were from four to 10 samples. The concentrations of 137Cs in fish species were in the range of 0.07 ~ 0.25 Bg/kg• ww except mackerel (2.69 ± 0.26 Bg/kg• ww) which was collected in the Pacific Ocean of Japanese eastern side. 134Cs in this mackerel also was detected with the concentration of 1.94 ± 0.44 Bg/kg• ww. But 134Cs was not detected in all other measured species in this study. The average concentration of 137Cs in oyster was 0.06 ± 0.04 Bg/kg• ww in five samples. The concentrations of 137Cs in macro algae were below detection limit (0.02 Bg/kg̶ . Target species included eleven species of fishes: mackerel (Scomber japonicas) anchovy (engraulis japonicus) hairtail (Trichiurus lepturus) roskfish (Sebastes schlegeli) walleye pollack (Theragra chalcogramma) bluefin tuna (Thunnus thynnus) yellowfin Tuna (Thunnus albacares) saury (Cololabis saira) stingray (Dasyatis akajei) flatfish (Paralichthys olivaceus) squid (Todarodes pacificus), one species of shellfish: oyster (Crassostrea gigas) and three species of macro algae: laver (Porphyra tenera) laminaria (Laminaria japonica) sea mustard (Undaria pinnatifida).
