[ RadSafe ] Scientists: Test West Coast for Fukushima radiation

Tue Mar 11 13:26:09 CDT 2014

Hi Roger,

Thanks for the links.  While I am inherently skeptical of not having rigid control of the sampling process (hard earned lessons here :}   ),

 it is interesting to see the dissipation of the 134Cs and the near-uniformity of the 2014-measured 137Cs which overlaps nicely with previously measured values.   

Apparently the method here is to have 20 L of seawater collected, then isolate the Cs on a resin and count it on a high end, high resolution gamma spectrometer, and they even throw in a cold Cs "tracer."      Intersestingly, they report values decay corected to the Fukushima peak release, so you have to "uncorrect" them for current values.....  

Is there any reason to think at this point, that there could be a sample which is not yet diluted to 137Cs background levels or 134Cs MDA?

They are obtaining the samples from trained volunteers and doing the
 testing - take a look at this website -

Apparently some "scientists" are crowd-sourcing the samples from volunteers along the west coast, according to the report.

What could possibly go wrong?

Gosh I hate when they make misstatements like that. A lot of my friends ask

me questions about it when this happens.

USA Today has a piece on Fukushima contamination. Here's a sample:

"In Oregon, state park rangers take quarterly samples of surf water and sand

at three locations along the coast. The water is analyzed for Cesium 137 and

iodine 131. Both of those already exist in the ocean at low levels from

nuclear testing decades ago."

Boy, that I-131 is sure persistent!
