Fukushima: “Enough with ‘plume’ already. That sounds far too discrete, finite and hence manageable. Call it what it is, a constant never ending torrent of insane, undiluted poison heading for our West Coast”…

University of Massachusetts – Dartmouth, FVCOM Modeling Assessment of Japan’s Tsunami Event and Impacts of Radionuclides on the Pacific Ocean:

Title quote from comments section of this article... -DS]

[...] The amount of radiation released in the nuclear accident has threatened the coastal environment with potential impacts on the Pacific Ocean. An international research team was established with the aim of [...] assessing the impact of radionuclides on the surrounding countries around the Pacific. [...] The ocean model used for this activity is the global-coastal nested FVCOM model system. FVCOM is an unstructured grid Finite Volume Community Ocean Model (FVCOM) [...] At 50 m, particles spread over a large region and reach the western US coast after 5 years. [...] At 200 m, particles stay in the narrow region and move eastward. >> Watch all 16 forecast models on the university’s website here (Bottom of page)

Radioactivity levels in the seawater outside of the troubled Fukushima Daiichi Nuclear Plant continue to ignite concerns over the spread of highly radioactive material [...] The unusually high rates of radiation found in the turbine rooms — and now in the ocean — have fueled concerns that water may be seeping from at least one of the reactor cores, leaks that could release longer-lasting and much riskier forms of contamination.” Government officials have stated that they are not sure whether the primary containment vessels have been breached. [...] Officials continue to stress that contaminants will become diluted as currents carry them farther offshore. [...] ASR modeling of the radioactive seawater tells a different story, cause for serious alarm. While these models do not estimate levels of radioactivity in the surrounding waters, the assumption that nearby currents will quickly dilute the radioactive material does not appear to be accurate.

    Effects of Airborne radiation from Fukushima, Hanford, WA
    Marco Kaltofen, Environmental Professor, Worcester Polytechnic Institute

    “I don’t think anyone thought this day would come and from Fukushima it has…’

    ‘….We’re all going to be dealing with Hanford, the greatest radioactive sight in North America for thousands of years to come…I don’t know if it can ever be cleaned up..’

    ‘..i don’t think it matters where you move to….we need our government to start setting up monitoring systems and providing accurate information to us…it is not at all hard to do….’
