Portland-area had highest Iodine-131 deposition in US at 5,100 Bq/m² by April 5 -Gov’t Study

Title: Fission Products in National Atmospheric Deposition Program—Wet Deposition Samples Prior to and Following the Fukushima Dai-Ichi Nuclear Power Plant Incident, March 8–April 5, 2011

I-131 was quantified and adjusted for decay to the time of sample collection for five whole-water wet-deposition samples from California, Colorado, and Washington. The activities of the quantified I-131 ranged from 29.6 to 1,090 pCi/L, and calculated deposition values ranged from 211 to 5,100 Bq/m2. Several weeks transpired between sample collection and analysis of the I-131 in the water samples, which were prioritized for analysis from west (high priority) to east (low priority). Therefore, I-131 activities likely decayed in most of the samples before they could be measured.

    Yes I 131 levels likely decayed before they could be measured, why???

    Because they take TOO DAMN LONG to test things, negligent homocide again!!!

    There was enough time, however, to deep fry thousands of human thyroids of U.S. Citizens!!!

    I really hope there are some lawyers out there capable of crafting class action lawsuits…we can't keep letting the govt steal our money, steal our health, and giving in return halfassed, SLOW responses to nuclear emergencies that warrant clear warning and evacuation, banning food and water supplies when necessary.

    These numbers sound a little more realistic than other recent articles. They can't perpetuate the FukU/Chernobyl Coverup much longer!

    • There should be a site made where people can report there ills as Nation wide as there is one in Japan, so we can correlate the affects of the fallout and symptom's and our health !

      • datura17

        it has been tried however those sites get shut down, didnt google or yahoo try that? i think it starts showing anomalous areas of disease and tptb dont want that. plus goofballs add bogus info.

      I'm surprised this USGS report didn't get more attention from ENENewsers.

      Daily air filter results would have been more helpful, but at least these rain results give some info.

      Here's one rough comparison of Chernobyl vs. Fukushima (it isn't a perfect comparison because samples were collected one day for Chernobyl and 2 weeks for Fukushima)


      Fukushima – 3/15-3/29 = 5,100 Bq/m2
      Chernobyl – 5/5/86 = 1,200Bq/m2
      Fukushima – 3/15-3/29 = 1,090 pCi/L
      Chernobyl – 5/13/86 = 6,620 pCi/l

      If you want to compare, here's the Chernobyl info:

  • Alice Alice

    Well, Thank You for telling us about the fallout after the fact.

    We'll be sending all our radioactive sputum to you.

    Thanks Alice,…was wondering where to send in my sputum!

    Has anyone seen the live feed. Something went "pop" yesterday and about 2 square miles of Fukushima is still covered in steam…

    There appears to be radiation literally raining down upon Earth. In several new YouTube videos shot in the United States and Canada, radiation-detecting Geiger counters are shown buzzing at an alarming rate when aimed at wet grass and puddles shortly after it has rained….


    Ahahaha, they call it Live Science…

    You know Portland folks are the most dedicated greenies. More than any other place I've been, including Seattle.

    And they are living right in the line of fire of the worst environmental disaster of all time – and won't even pay attention.

  • Best place to hide a secret is RIGHT OUT IN THE OPEN, IN THE RAIN.

    Everyone loves the rain

    Run in the rain

    Splash in the puddles

    Roll in the mud

    Dogs spraying everyone with shaken off rainwater

    Yup, that is the best place to hide the rivers of toxic radiation coming from FUKU every day, even up to today.

    No one will ever think to look there.

    Portland #1, Alot of intestional problems here for us in the portland area. Severe, Hospital, antibiotics & long recovery, no fun…not normal. Were back on bottled spring water, should have never quit. Makes ya wonder….

  • beamofthewave

    At Oregon State University web site there is an article about the debris coming from Japan and that it is not radioactive because it has been in the ocean and the ocean washed away the iodine and cesium. Is that true? Can the ocean do that?

  • Has this been posted yet? It's a long article with lots of info on what's coming at us right now in addition to hot particles and rain fallout (mainly aerosolized ocean spray):

    Uranium-filled "buckyballs" bound for West Coast:
