Forbes, Feb. 20, 2013: […] Last week one of the authors of the study from last year, Daniel J. Madigan from Stanford University’s Hopkins Marine Station—along with five other scientists— published a new follow-up study. The main question that this new study wanted to answer: Would the migratory Bluefin tuna show up again a year later off the coast of California carrying radiation from Fukushima? The answer was yes. That means, ultimately, that there is still a high level of radiation in the waters near the Fukushima plant most likely because, as marine chemist, Ken Buessler, asserts, the plant is still leaking radiation into the ocean nearly two years later. […]
After the North American governments refused to fund testing, oceanographer Ken Buesseler, a senior scientist at the non-profit Woods Hole Oceanographic Institution in Woods Hole, Mass, along with Nicholas Fisher, a marine sciences professor at the State University of New York at Stony Brook, and other concerned scientists, managed to secure private funding for a Pacific research voyage. The results?
Cesium levels in the Pacific had initially gone up an astonishing 45 million times above pre-accident levels. The levels then declined rapidly for a while, but after that, they unexpectedly levelled off.
In July, cesium levels stopped declining and remained stuck at 10,000 times above pre-accident levels.
This means the ocean isn’t diluting the radiation as expected. If it had been, cesium levels would have kept falling.
The finding suggests that radiation is still being released into the ocean long after the accident in March, 2011.
On 28 Oct 2011, the Atmospheric Chemistry and Physics Discussions (ACPD) group released a paper titled “Radionuclide release from Fukushima Nuclear Power Plant”. This paper details the release of two isotopes, Xenon-133 and Caesium-137 into the atmosphere following the earthquake/tsunami on 11 March 2011.
Differing from previous maps and projections based upon hypothesis of wind direction and atmospheric conditions, this study looks BACK and can definitively determine the amount of release. The results are extremely disturbing, not just for Japan, but for Hawaii, Alaska, Canada, the U.S. and really, the entire world.

The article went on to say: “After 10 years, the concentrations become nearly homogeneous over the whole Pacific, with higher values in the east, extending along the North American coast with a maximum (~1 — 10 -‘4) off Baja California,” a new research report states.”
Then, on August 22, 2012, Japan's NHK News reported that the Fukushima Daiichi nuclear plant detected radiation levels 380 times the government safety limit in a fish caught off Fukushima Prefecture.
