评估了福岛第一核电站附近的水箱中储存的污染水计划排放到太平洋对人类和水生生物群的放射性影响。对储罐中10种主要放射性核素（H-3、C-14、Co-60、Sr-90、Tc-99、Ru-106、Sb-125、I-129、Cs-134、Cs-137）的总活度进行了估算。应用隔室模型POSEIDON-R计算水、海底沉积物和生物群中每种放射性核素的活度浓度，以及食用海产品对海洋生物和人类的相应剂量。预计今后海产品中放射性活度的浓度不会超过日本的食品安全限值。计算出的人体最大承诺有效剂量小于1 μ Sv/年，其中I-129和C-14的贡献最大。非人类生物群的最大吸收剂量为每年0.05至20 μ戈伊，这意味着预计不会产生有害影响。
The radiological impact for human and aquatic biota as a result of a planned release of contaminated water stored in tanks near the Fukushima Dai-ichi Nuclear Power Plant to the Pacific Ocean is assessed. The total activity for 10 dominant radionuclides (H-3, C-14, Co-60, Sr-90, Tc-99, Ru-106, Sb-125, I-129, Cs-134, Cs-137) in tanks is estimated. The compartment model POSEIDON-R is applied to compute the concentration of activity for each radionuclide in water, bottom sediments, and biota, and corresponding doses to marine organisms and humans from seafood consumption. Predicted concentrations of activity in marine products in future will not exceed food safety limits in Japan. The computed maximum committed effective dose to humans is less than 1 mu Sv per year with the highest contribution from I-129 and C-14. Maximum absorbed doses to non-human biota are in the order of 0.05 to 20 mu Gy per year, meaning that no deleterious effects are expected.
