"Over the next week we will be testing some tomatoes and carrots. Updates on those to come."

Were California grow carrots free of Cesium? Were the tomatoes?

This is vital information in determining what is safe to feed both children and adults.

The US government is not giving any information to the public.
That is VERY disturbing to me.
Thank you for your help.

CARROTS

"MDA" is the estimated minimum detectable activity for a given isotope in the detector.

I found the test results after posting this thread, however when it states: less than MDA
Does that mean there was no detectable levels of Cesium in the carrots?

The graphs presented here:

As a layman I don't see any reference to Cesium, perhaps the symbols or nomenclature is not that of the element, what exactly is that telling us?

Also I note that you state:
"The number in parentheses is the number of kilograms of the item that one would need to consume to equal the radiation exposure of a single round trip flight from San Francisco to Washington D.C."

Do you mean to suggest that the long term effects of such a flight equal that of ingesting food contaminated with Cesium?

Carrot test results

The page you found is the page showing the gamma-ray spectrum for the carrot sample. Each sample has its own page where anyone can see the gamma-ray lines and the isotopes that were detected, but there aren't any quantitative results shown there.

I'm not sure if you ended up finding this, but the carrot results are posted on the Food Chain samples page, linked from our main radiation testing page. A direct link to the carrot test results is here. There were no detectable levels of cesium-134 or 137 in that sample.

"Do you mean to suggest that the long term effects of such a flight equal that of ingesting food contaminated with Cesium?"

Yes, essentially; we use the total effective dose equivalent to compare the two doses.
