Vertical profiles of radiocesium (134Cs and 137Cs) were measured in the western subarctic area of the North Pacific in 2017. The highest concentration of 134Cs, which was derived from the accident of the Fukushima Dai-ichi Nuclear Power Plant in 2011

We measured dissolved radiocesium (134Cs and 137Cs) in seawater collected in the western subarctic area of the North Pacific Ocean, Bering Sea, and Arctic Ocean in 2015 and 2017. The radiocesium released from the accident of the Fukushima Dai-ichi nu

The cesium depuration mechanisms were studied in Japanese rockfish Sebastes cheni off Fukushima, in which the radiocesium level remains higher than in other teleost. Samples were collected approximately 5 km south from the nuclear power plant during

The Fukushima Dai-ichi Nuclear Power Plant (FNPP1) accident in March 2011 resulted in serious radiocesium contamination of the North Pacific Ocean. Most of the radiocesium was dissolved in seawater and transported by surface currents and subduction o

According to the 10 years environmental monitoring by TEPCO, as shown in Fig. 1, the radiocesium concentrations in rockfish and some flounders were higher among fish collected from the same port area of the Fukushima Dai-ichi nuclear power plant. Ove

Cruise SoSo 5 Rivers took place during October 2014 off the coast of Fukushima Prefecture shortly after the passage of two typhoons. Detection of dissolved 134Cs and 137Cs in all samples reflected contamination caused by accidental releases of radioc

The world's oceans act as a sink for artificial radionuclides as well as for other anthropogenic pollutants released into the environment. Owing to physical and biogeochemical processes in the ocean, artificial radionuclides in the ocean are redistri

In 2015–2017, we measured activity concentration of radiocesium in the western subtropical gyre of the North Pacific Ocean and revealed the time evolution of radiocesium derived from the Fukushima Dai-ichi Nuclear Power Plant (FNPP1) accident betwe

We conducted enhanced surface water sampling at more than 80 stations in coastal regions on both the Japan Sea and Pacific Ocean sides of Japan in winter 2015/2016 to examine the recirculation behaviour of FNPP1-derived radiocaesium in the surface la
