Iodine-133 Cesium-134 Cesium-137 found again in California milk

So what do these products imply about the state of the reactors?

http://cdph.ca.gov/programs/Documents/CDPH-RHB-RadReport-2011-05-16.pdf


CalPoly Dairy Farm 5/2/2011 detection of:
Iodine-131 @ 4.14 pCi/liter
Cesium-134 @ 4.55 pCi/liter
Cesium-137 @ 5.11 pCi/liter

Compare to March sample:
CalPoly Dairy Farm 3/28/11 detection of:
Iodine-131 @ 3.33 pCi/liter

1. Do we know their origin?
and without error bars, it's impossible to make comparisons between the two samples.

2. The origin of the products is obviously Fukushima unless there is a core melting in CA
This is a government sampling result and I included the .pdf for further info.

3. Cool.
Although I wouldn't be surprised if there were a few mystery meltdowns in China every year.

9. China only has a handful of reactors.
It would be tough to have a few meltdowns annually and have the rest of the world miss that fact.

5. Do those isotopes ever occur naturally?

4. are there baseline readings pre-Fukushima?

6. The baseline readings are non detect
You don't see these products unless there is a plant incident.

17. Wrong.
"Radioactive cesium is present in soil around the world largely as a result of fallout from past atmospheric nuclear weapons tests. The concentration of cesium-137 in surface soil from fallout ranges from about 0.1 to 1 picocurie (pCi)/g, averaging less than 0.4 pCi/g (or 0.3 billionth of a milligram per kilogram soil)."

http://www.ead.anl.gov/pub/doc/Cesium.pdf

The density of milk is 1030 grams/liter, so the 5.11 pCi/liter in CA milk is about 1/100 of the Cs-137-derived radiation that's already present in the soil upon which the cows walk.

Moo. :D

20. Wrong, the sampling showed non-detect previously
So that is the measure in question, and we know where it is produced.

You are wrong. Wrong, wrong, wrong. Care to admit it? :shrug:

8. It Means They are Still Critical
Edited on Wed May-25-11 12:10 PM by AndyTiedye
Iodine 131 has a half-life of 8 days. It is increasing.

Re-criticality is happening.

The core has re-formed a critical mass on the floor of the containment.

10. Then what does it mean that it hasn't been detected at all since then?
Edited on Wed May-25-11 12:27 PM by FBaggins
And how did it get there when the same lab detected nothing in the air... Magic?

Just wondering.

11. The cesium levels imply no additional deposition
Which is confirmed by their air readings (as well as those done by Cal Berkely and the EPA).

The Iodine reading is awfully close to their detection level and thus may be drowned out with sampling error and variability (which cows ate which grass etc).

As pointed out on the previous post, without detecting more iodine in the air, it's a pretty big stretch to draw some conclusion for events thousands of miles away.

12. It was the crazy littoral waters Leopard sharks.
They did it. They went over there. Ate the fallout off the plant shoreline. Zipped back over here to the states at incredible speed, crawled ashore, and threw their dying bodies into the mouths of the cows.

13. Lol. Yep.
About as likely as the "fission restarted and massive new releases (that miraculously only show up in CA milk) have begun"

14. Hmmm. I think re-criticality is somewhat more likely.
But not conclusively proven yet.

15. Hard to determine "more" with that number of zeroes
They both look pretty unlikely from this side of the decimal point. :)
