Various kinds of radionuclides were released into the atmosphere and the sea from the Fukushima Daiichi Nuclear Power Plant on Tokyo Electric Power Co. (TEPCO) by the accident and then reached around our laboratories. Therefore the accident influence on our environment was investigated to measure the concentrations of cesium-134 ($$^{134}$$Cs), cesium-137 $$^{137}$$Cs, strontium-90 ($$^{90}$$Sr) and plutonium isotopes in seabed sediments. The values for $$^{137}$$Cs ranged from 6.1 to 300 Bq/kg (dry wt) and the ratio of $$^{134}$$Cs /$$^{137}$$Cs ranged from 0.48 to 0.77. The highest point of $$^{137}$$Cs concentration was observed at the northernmost station near Kitaibaraki City and the concentration was similar to report by MEXT.
