Title: Impact to US West Coast from Fukushima disaster likely larger than anticipated, several reports indicate

The new scientific paper, which will be published in November 1 edition of the journal Science of the Total Environment says that its research “clearly demonstrates how little dissipation [of radionuclides] occurred [between March 12 and 16] due to the nature of the rapid global air circulation system.”

The massive release of anthropogenic – or non-naturally occurring radionuclides such as cesium 137 and cesium 134 – by the meltdowns and explosions that rocked Fukushima Daiichi occurred in the five days following the beginning of the accident, the report says.


The report goes on to say that “the Fukushima radioactive plume contaminated the entire Northern Hemisphere during a relatively short period of time” after [3/11]


Bellona’s article ties in several past reports related to the Fukushima disaster:

  • Statement by Arnie Gundersen: “During April, the people in Seattle could have just as easily been in Tokyo for the amount of hot particles that were there”
  • Sickened Alaskan wildlife
  • Recent aerial radiation surveys on West Coast via helicopter
  • Food safety limits raised in US, Europe after 3/11

    The difference between a hot particle and a fuel flea is the size of the piece. A fuel flea is much larger than a hot particle afaik. According to recent information on the subject, hot particles are light enough to float on water and in air. Expect a wave of hot particles to arrive with the imminent bombardment of tsunami debris heading to North America. Perhaps they will need to somehow remove the particles from the beaches, especially along the shoreline. If they do not, then they may work their way inland on feet and wind.

    Wildfires in Washington State area-with large forest fire burning. Recent report mentions a firefighter death due to exposure to smoke from the fire. We all hope and pray for the family of this hero. And pray also he did not expire due to radiation contaminated smoke. Has anyone seen other comments/figures on amount of forest contamination on the east (Liberty Washington) side of the Cascades?

    The west coast did get a significant brunt of hot particles, but they weren't the only ones —>

    In March 2011 —>

    IODINE-131 —>

    ** Washington = 1,090 pCi/L
    ** Colorado = 464 pCi/L
    ** California = 185 pCi/L

    So, you see that more Iodine-131 was found in Colorado than in California

    CESIUM-134 —>

    Alaska = 55 pCi/L
    Colorado = 14 pCi/L
    South Dakota = 10 pCi/L
    California = 7.3 pC/L

    So you see that South Dakota & Colorado are higher than California

    CESIUM-137 —>

    California = 39 pCi/L
    Alaska = 26 pCi/L
    Colorado = 22 pCi/L
    South Dakota = 20 pCi/L
    Illinois = 15 pCi/L
    Washington = 5 pCi/L

    California tested the highest in Cesium-137, but Colorado, South Dakota & Illinois tested higher than Washington State

    Just an observation.

    P.S. >> and someday I believe it will be proven that Florida was one of the hot spots
