Now this is weird...a sample with I-131 from 5/2? I would have thought that it would be might hard to find I-131 on that date....
nothing surprising
I see nothing surprising about the date. It's not like fukushima has stopped spewing radiation into the environment, right?
I figured that the recent
I figured that the recent decline in levels in rainwater and air were indicating that atmospheric releases had subsided.
Doesn't it?
Declining levels in raiwater and air are indicating atmospheric release
have subsided. If they hadn't, we'd still be seeing I-131 of 4.3e-06 Bq/L
in air (the peak BRAWM result) vs. the steady decline to below MDA in the
last report. The last detected level in the BRAWM report was 4.0e-09,
which is a 1075 times lower than the 4.3e-06 Bq/L peak. And they had
to take a much larger sample to even detect that.
Rainwater results have gone from a I-131 peak of 19.85 Bq/L down to below
the MDA of 0.01 in the last report. The last detection was 0.08 Bq/L,
which had an MDA of 0.03 Bq/L. And was 248 times lower than the peak of
19.85 Bq/L.
As someone else pointed out, the levels detected in milk are hovering
around the BRAWM MDA. And the CDPH states the MDA for their milk sample as
2.80 pCi/L (0.10 Bq/L). Which is not too far above the CDPH MDA. Page 47:

So, I'm not sure what other evidence of declining levels and subsiding
releases anyone is looking for. Are there still releases from Fukushima?
Sure. But, no where near what got released in March.
More info here on the milk -
More info here on the milk - it shows collected 5/2 (NOT best by), with an activity of 4.14 picocuries/liter which works out to .15Bq/l = very low and I think below the MDA that the BRAWN team is using.
BTW, only one collection out of 20+ showed any radioactive substances.
It's all about location, and right about now, I'm kinda wishin' mine was in the Paraguay. I hear it is lovely there.
There have actually now been
There have actually now been two CDPH samples reporting
I-131.
3/28 sample (4/1 report) I-131: 3.33 pCi/L
4/4 sample 4(/6 report) No detections
4/11 sample (4/41 report) No detections
4/18 sample (4/20 report) No detections
5/2 sample (5/16 report) I-131 4.14 pCi/L
So, not only was a slightly higher level of I-131 detected than
the 3/28 sample, but the latest report is the first to have cesium
detected.
The BRAWM MDA for milk in their last report was 0.13 Bq/L.
So, *if* the BRAWM team had tested this, they should have
been able to detect 0.15 Bq/L (4.14 pCi/L).
