[ RadSafe ] Nuclear-News Claims Increasing levels of radioactive cesium in Vancouver area

We have two results so far from Vancouver/Seattle area, from Bamfield BC 
and Sequim WA, and both show detectable 137Cs at 1.3-1.4 Bq per cubic 
meter and no detectable 134Cs (less than 0.2 Bq per cubic meter).  The 
137Cs is consistent with pre-existing Cs from 1960's fallout, and lack 
of 134Cs suggests that the Fukushima plume has not yet reached these 
coastal areas (where they are seeing the star fish dye off's).  These 
are the facts.
see http://www.ourradioactiveocean.org/results.html

Regarding the interview between these two reporters (not scientists), 
there are many statements that are in error or exaggerated, and ENE uses 
[....] to exclude any content that they don't want you to read from the 
interview itself.

Radioactivity can be of human health concern, but not at the levels we 
are seeing along the west coast of N. America.

Sincerely, Ken Buesseler
