Japan & U.S. Gov’t Experts: West Coast hit by radioactive plumes from both massive Fukushima explosions — Maps of L.A. and San Francisco covered in red clouds removed from latest paper — Total releases ‘clearly larger’ than previously claimed — ‘Significantly’ higher discharges flowed toward U.S.

Japan & U.S. Gov’t Experts: West Coast hit by radioactive plumes from both massive Fukushima explosions — Maps of L.A. and San Francisco covered in red clouds removed from latest paper — Total releases ‘clearly larger’ than previously claimed — ‘Significantly’ higher discharges flowed toward U.S. (ENENews, Feb 3, 2015):

Excerpts from study by scientists from Japan Atomic Energy Agency, Japan Meteorological Agency, NOAA, UK Met Office, Canadian Meteorological Centre, 2014-2015 (emphasis added):

  • We estimate a detailed time trend of atmospheric releases during the [Fukushima] accident by combining environmental monitoring data with atmospheric model simulations from WSPEEDI-II (Worldwide version of System for Prediction of Environmental Emergency Dose Information)
  • The plume movement over the Pacific Ocean [is shown in] the WSPEEDI simulation
  • 12 March: The WSPEEDI simulation showed that the plume discharged by the hydrogen explosionreached the west coast of the United States on 18–19 and 21–22 March, Sand Point in Alaska on 20–21 March, and Oahu in Hawaii on 20–21 March. [The highest release rate over the course of the disaster occurred Mar. 12 at 15:30 JST, see Table 5]
  • 13 March – evening of 14 March: The plume discharged… over the Pacific Ocean and increased air concentration at Sacramento California, Melbourne Florida, Sand Point Alaska, and Oahu Hawaii… a hydrogen explosion also occurred [during this time period] at Unit 3 at 11:01 on 14 March.
  • Noon of 16 March – early morning of 20 March: WSPEEDI simulation shows that the plume primarily flowed toward the Pacific… this plume affected the air concentrations… in Alaska and Oahu… [T]he release rate is revised by using recently obtained monitoring data. The release rates [are] several times larger than those estimated previously for the afternoon on 16 March to the noon on 19 March.
  • Interestingly, when the plume flowed toward the Pacific Ocean, our new source term often agreed well with that of Stohl et al. (2012) [the Stohl et al. cesium-137 release estimate by is far the highest of any included in this study, see Table 9]
  • The total release amounts of 131I and 137Cs…  are clearly larger than those of Terada et al. (2012). These increases were mainly due to an increase of the release rate when the plume flowed over the ocean
  • The total amounts of released 131I and 137Cs estimated in this work… were clearly larger than those of the previous work for both radionuclides. The major reason for this increase was that when the plume flowed toward the Pacific Ocean we directly computed a significantly larger release amount

Note that another version of this study published on Jan 30, 2015 is missing the WSPEEDI maps (Fig. 6), as well as nearly all references to Fukushima fallout reaching North America (pdf)

  1. Next month, it will be four years that radioactive monster has continued it’s destruction of human life without any intelligent folks getting together to try to resolve this ongoing genocide of our Pacific ocean that alive provided 50% of the world’s oxygen. Dead, it will provide none, as the behavior of the dying sea animals have proved. Gasping for air, millions of starved, diseased sea creatures have landed on our shores. Awful sea creatures from the depths, ones we never knew existed have washed ashore…………even fish with teeth…..ugh.

    Big sea creatures have gotten trapped in our bays looking for food and air, finally beached and died. The vulture animals provided so kindly by nature won’t touch them, they can sense the radioactive poisons in them, so leave them on our once beautiful beaches to rot.

    About three years ago, hundreds of dead sea turtles washed ashore in Costa Rica. Dogs, not provided with the sense of vulture animals, raced down to the beach to eat them. They ate them, and died instantly.

    The disaster now cannot be forestalled, it has been allowed to go on too long. We confront a dead ocean, loss of 50% of our oxygen, broken food chain, destroyed soil, air and water………we face our own extinction.

    Even worse, on the west coast in CA, we are in year five of a terrible drought that is impacting food prices sharply, and supply will soon be a problem. 67% of the US is in a drought regardless of a few Winter storms………the outcome for all of us, especially in CA, is death.
