“Little Dissipation Occurred…

Due to the Nature of the Rapid Global Air Circulation System”




We warned mere days after the Japanese earthquake that the West Coast of North America could be hit with radiation.


Our concerns - unfortunately - have been validated. See this and this.


The peer-reviewed scientific journal Science of the Total Environment reports:

Massive amounts of anthropogenic radionuclides were released from the nuclear reactors located in Fukushima (northeastern Japan) between 12 and 16 March 2011 following the earthquake and tsunami.


Ground level air radioactivity was monitored around the globe immediately after the Fukushima accident. This global effort provided a unique opportunity to trace the surface air mass movement at different sites in the Northern Hemisphere.




The analysis of the air mass forward movements during 12th -16th March showed that the air mass was displaced eastward from the Fukushima area and bifurcated into a northern and a southern branch outside of Japan (Fig. 3).



Fig. 3. The two main air mass branches (centroids) from Fukushima Daiichi nuclear
power plant from 12th to 16th March. Each centroid has a temporal coverage of
192 hours (8 days) and initial height of 1000 m. The number is the identification
number of the centroid and the percentage indicates the number of hourly backward
trajectories occurring in that cluster. 1 and 2 in the figure stands for the south and
north branches of the Fukushima radioactive plume.




This eastward bifurcation of air masses is in agreement with the simulation of the potential dispersion of the radioactive cloud after the nuclear accident of Fukushima (Weather OnlineWebsite of United Kingdom, UK, 2012).




This work clearly demonstrates how little dissipation occurred during this time due to the nature of the rapid global air circulation system, and the Fukushima radioactive plume contaminated the entire Northern Hemisphere during a relatively short period of time.



Note:  The West Coast of North America is also at risk from ocean radiation.


The Department of Homeland Security and National Nuclear Security Administration recently sent low-flying helicopters over the San Francisco Bay Area to test for radiation. But they almost certainly will not make their findings public.
