Title: Canopy-Forming Kelps as California’s Coastal Dosimeter: 131I from Damaged Japanese Reactor Measured in Macrocystis pyrifera (ACS Publications)

Corona Del Mar (Highest in Southern California)
- 2.5 Bq/gdwt (gram dry weight)= 2,500 Bq/kg of dry seaweed
Santa Cruz (Highest in Central California)
- 2.0 Bq/gdwt = 2,000 Bq/kg of dry seaweed
Simon Fraser University in Canada also tested North American seaweed after Fukushima:
- “In samples of dehydrated seaweed taken on March 15 near the North Vancouver SeaBus terminal, the count was zero; on March 22 it was 310 Bq per kilogram; and by March 28 it was 380 Bq/kg.” -Vancouver Sun
- Seaweed in Seattle also tested positive for iodine-131; levels were not reported -KIRO
- No results after March 28 were reported

Sad that Corona Del Mar got the most radiated.

5/2012 – US Radioactive Fallout Measurements In US Beef, US Radiation Tool; via A Green Road Blog

It is starting to look like the radiation counts are going up gradually over time.
FUKU is still leaking, so the radiation is slowly increasing all over the USA, which is downstream of whatever is coming out over there.
At least this is the theory.. now it is up to TEPCO to put up radiation monitors and PROVE the opposite, on stacks, in the ocean, in the basements, in the groundwater, on land around the plant.
No transparent radiation monitors? The meters also need to checked for calibration and accuracy by non industry, non govt. folks.
No fair turning calibration screws down to the point where it is all 'safe'.

This is indeed shocking proof that the Pacific has been permeated from East to West! But what about the levels in fish then? What were the levels in Californian seaweed before Fukushima? Were they periodically tested then for radionuclides or only since Fuku? Could these levels be the result of California's reactors over the years?
Either way, after looking at the results of ongoing scientific research into Chernobyl's legacy, we can safely expect the worst to keep unfolding!! We have truly taken the biggest piss of all so far in our beautiful pond!!!!!!

If it was cesium there would be more difficulty proving the source was not California nuke plant releases. Because iodine 131 (131I) is a much shorter lived radionuclide, the evidence of when the levels rise and fall can show very good proof of what the source of contamination was.

This is increasing as the fallout !

Okay, here's the question: The March 15 is from which year? Is this a recent study? Or are the figures from one year ago? It makes no sense that it's Iodine showing up now because with a half-life of 8 days, it has an effective radioactive life of 80 days (factor of 10). So if Iodine is showing up on March 15, 2012, what's the newly leaking source? If from a year ago, why is it taking so long to show up? Anyone clear on this?
Report Comment
wow, that was just from rainout and fallout, theres no way that was from radiated ocean water transversing the pacific, the land should reflect higher numbers than that now.
Report Comment
But if it's the case this was a result from rainout and fallout, then crops would surely be reflecting far higher numbers, no? Rain will dilute to a degree when it hits the sea but on land I imagine it's going to leave the radionuclides behind in the soil to be taken up by vegetation, no?
Report Comment
Apparently seaweed takes in more iodine than crops. Also, the iodine decays quickly so it would only be showing up for a short period.

Iodine-131 has a short half-life of 8 days, so it pretty much disappears after 80 days. But iodine-129 is also a fission product, and has a half-life of 15 million years. Nobody ever measures I-129. Even if the 129 is a tiny percentage of the 131 amount, it will accumulate in seaweed over time.

Seaweed is a terrific source of iodine.

I recall the Japanese ingesting kelp for it's ability to block radioactive iodine from the thyroid. Hiroshima is what prompted it. Too bad the kelp is full of radiation now

So according to my terrible math:
http://www.ccohs.ca/oshanswers/phys_agents/ionizing.html
http://www.radprocalculator.com/Conversion.aspx
12.46mSv approx effective dose in Santa Cruz using above sites if you ate 1 gram I think. So that's like being a nuc plant worker for 2.492 months (freely mixing conversions in ways never before thought of.) Eat 4.82 grams back then and you are nuc max for a year???
What else does kelp absorb?
High in Calcium = Cesium
Iron = Plutonium
Magnesium = ?
Darn, I loved seaweed.

Did you allow for the gamma emission that occurs when a majority of the Xe-131 decays from its meta-state to its stable state? That should double your estimate.
Report Comment
And here's a clue: it was published by the authors on March 6, 2012, but the data is from March 15. Prescient? Or last year's numbers? We really have to be clear on this stuff or risk discrediting the valid information.

o.k., now i have to take a break from enenews. too much to digest, thanks, and have great weekend.

i was under the impression that when certain nuclides enter the body it slowed there decay or increased there half life is that true?
