Cesium 134 transport to American west coast

Atmospheric back trajectories from sites where radioactive fallout was measured in NADP wet deposition samples. NOAA’s HYSPLIT model was used for this analysis

Measurement of Radioactive Fallout from the March 2011 Fukushima Nuclear Reactor Incident Source: U.S. Geological Survey (USGS) in collaboration with the National Atmospheric Deposition Program

The study found concentrations (activity) and fallout (deposition) of radioactive iodine and radioactive cesium in significant number of samples. Detectable quantities of Iodine-131, Cesium-137, and Cesium-134 were observed at 21% of the 167 tested locations. Concentrations of I-131 detected in 5 samples ranged from 29.6 to 1090 picocuries per liter (pCi/L). Concentrations of Cs-134 detected in 23 samples ranged from 0.4 to 55 pCi/L. Concentrations of Cs-137 in 33 samples ranged from 0.70 pCi/L to 39 pCi/L.

[Note: Cs is Cesium, and this analyzes only one release on one day from Fukushima Daichi- not the multiple or ongoing releases]

“A single release of 1015 Bq of 137Cs, which occurred on March 12, 2011 from damaged Fukushima NPP was analyzed. The initial plume height, as a result of initial vertical velocity and buoyancy, was kept to be at 2000e3000 m. The meteorological data and simulated trajectories revealed that the arrival times of particles released on 11 March, 2011 and 12 March, 2011 were different, and the particles were transported at different altitudes. It was also obvious that the jet stream affected the transport of emitted particles at upper atmospheric levels. Examples of the trajectories simulated using the Lagrangian dispersion model show (Fig. 1) that the first signs of Fukushima released radionuclides could be detected in the European countries (e.g. Island) on 20 March, 2011.”

Newspaper ignores scientific models that show Fukushima radiation impacting West Coast — Fails to inform readers by only reporting on discredited tsunami wave-height map — “What illness of the mind must people have to lie about the threat?” (ACTUAL FORECAST MODELS)
Published: January 24th, 2014

In reality, the Fukushima radiation forecast models published by scientific journals, governments, and universities show a more troubling situation for the West Coast than the discredited tsunami wave-height map. The tsunami map shows the impact being distributed throughout the entire pacific, with South America getting the worst of it. The actual Fukushima radiation transport models show the contamination heading due east, directly to North America’s west coast. Here are a some examples (note that none of these models take into account the ongoing releases from Fukushima of hundreds of tons of contaminated water every day) [400 tons per day]
