We can still not thinking "well over Pacific Ocean = who gives a shit ..." because this is A NO GO way to think!

Based on our data, we conclude that the radionuclide contamination from the Fukushima Dai-ichi NPP caused harmful effects on Z. maha at physiological and genetic levels.

We cannot evaluate the effects on humans directly from the results of the Z. maha study. However, considering the exceptionally large amounts of radioactive materials released into the en- vironment, which according to a news release (August 26th 2011) from the Japanese Ministry of Economy, Trade and Industry was 168.5 times as large as the Hiroshima atomic bomb (this is likely a significant under- estimate) [28,112,113], underestimating the effects on organisms (including humans) and ecosystems without any experimental evidence is not advisable.

At this point, nobody can scientifically present conclusive data demonstrating that the long-term low-dose exposure in the Fukushima area is safe or unsafe for humans, not to mention for humans with physical or mental weaknesses and those who will be born in the next generation. “No data” should not be confused with “safe”.

The highest total Cs concentration (18700 Bq kg-1) was found in masu salmon in March 2012 from the Sousou region near the F1NPP site (Table 2 and Figure 3); such a high concentration was not found between April 2012 and March 2014. Although each radiocesium isotope concen-tration decreased gradually, there were still detectable amounts in freshwater fish in Fukushima prefecture that exceeded 100 Bq kg-1 (i.e. the Japanese safety limit) of 134Cs and 137Cs even three years after the F1NPP accident.

The 1.3 million cubic meters/tons of radioactive waste water at the Fukushima Daiichi plant, currently in tanks, is scheduled to be discharged into the Pacific Ocean this year https://perma.cc/AB89-TMUR
