According to a news article (not exactly PNAS) the Long Beach State biology prof says cesium is concentrated 20-fold in kelp. Samples will be dried, ground to a powder, and counted by Lawrence Berkeley national lab. Can't ask for better analytical capabilities.

Thanks Eric, good to know what is going on off our Pacific coast.
Just wondering if there is a rationale to think one may observe Cs-134 in kelp when it is not observable in sea water with a method that has an excellent "concentration factor?"
It seems that it would be much more difficult to get the equivalent of 20kg of plant material into your well detector!

Apparently, at least one radiation safety specialist from SDSU is going to be involved and I've pointed him to the annual radiological environmental operating reports for the two big nukes in California. I know that for the San Diego and Orange County areas, kelp does show considerable amounts of I-131, all from medical administrations. The highest levels are found in the immediate vicinity of the major sewage treatment outfalls. Cs-137 is still detectable in many samples, including kelp, from weapons testing and Chernobyl. Fukushima can only add a little to that. Maybe Cs-134, if detectable, will prove Fukushima.
