  •  Really scary. Am really afraid for the Salmon and (12+ / 0-)

    Striped Bass fisheries on the west coast.

    if a habitat is flooded, the improvement for target fishes increases by an infinite percentage...because a habitat suitability index that is even a tiny fraction of 1 is still infinitely higher than zero, which is the suitability of dry land to fishes.

    •  Until some real testing is done, (14+ / 0-)

      Perhaps Pacific fish is not a good idea.

      •  HAS any testing been done? (1+ / 0-)

        ARE west coast fish showing higher levels of radioactive contamination?

        •  Yes, testing has been done (2+ / 0-)

          I don't know about salmon and striped bass, but pacific bluefin tuna has been of particular concern since radiocesium from Fukushima was detected in it in 2012.  The following paper discusses what was found:

          http://www.pnas.org/...

          To excerpt from the conclusions:

          This study shows that the committed effective dose received by humans based on a year’s average consumption of contaminated PBFT from the Fukushima accident is comparable to, or less than, the dose we routinely obtain from naturally occurring radionuclides in many food items, medical treatments, air travel, or other background sources. Although uncertainties remain regarding the effects of low levels of ionizing radiation on humans, it is clear that doses and resulting cancer risks associated with consumption of PBFT in eastern and western Pacific waters are low and below levels that should cause concern to even the most exposed segments of human populations. Fears regarding environmental radioactivity, often a legacy of Cold War activities and distrust of governmental and scientific authorities, have resulted in perception of risks by the public that are not commensurate with actual risks.
          There is a new preprint currently on Arxiv (http://arxiv.org/...) reporting that Alaskan salmon collected in Sept. 2013 had no measurable Cs-137/134.  Preprints should be consulted with some caution because they are not yet published in journals.
