Abstract
We investigated the distributions of the artificial radionuclides Cs-137, (239)(+)(240)pu, and Sr-90 in the various marine products around Korean Peninsula collected in 2015-2017. The activities of Cs-137, Pu239+240 , and Sr-90 were in the ranges of 12.2-258.4 mBq kg(-1), 0.014-1.879 mBq kg(-1), and 11.3-18.3 mBq kg(-1), respectively. The higher Pu-239+(249) (a factor of 10-50) relative to fishes were observed in mollusks. Cs-137 in fishes were significantly enriched with growths. The calculated concentration factors (CFs) of Cs-137, Pu-239+(240), and Sr-90 in marine products were 7-143, 3-407, and 15-25, respectively. Overall, no noticeable artificial radioactivity was detected in marine organisms when comparing these results with previous data reported before the Fukushima nuclear accident and recommended CF values. The annual effective doses of Cs-137, Pu239+240, and Sr-90 by seafood consumption in South Korea were estimated to be 1.1 x 10(-4), 1.6 x 10(-5) and, 2.9 x 10(-5) mSv yr(-1), respectively, which is insignificant relative to that of natural radionuclides.
