Calif Dept. of Public Health Latest Report

Here's the link to the latest CDPH results.

They detected it in milk again.....

I don't believe the DIL for Cs-134 & Cs-137 in milk is correct. The
DIL for those isotopes is 33,000 pCi/L.

No detection of any isotopes in the air up through 4/28/2011

Milk: Trace amounts of radiation was detected in the milk sampled from the San Luis Obispo area.

CalPoly Dairy Farm 5/2/2011 Detection of:
Element pCi/L Dose (millirem/week)
Iodine-131 4.14 0.016
Cesium-134 4.55 0.003
Cesium-137 5.11 0.002

The Iodine-131 concentration level detected in the milk sample is 1,122
times less than standard of the US FDA (4,645 pCi/liter of milk). The
resultant dose is approximately 0.016 millirem per week. Further, Iodine-
131 has a physical halflife of 8 days, which means Iodine-131 detected in
the milk sample decays very quickly. The Cesium-134 concentration
in the milk sample is 1,021 times less than standard of the US FDA (4,645
pCi/liter of milk). The resultant dose is approximately 0.003 millirem per
week. The Cesium-137 concentration in the milk sample is 909 times less
than standard of the US FDA (4,645 pCi/liter of milk). The resultant dose
is approximately 0.002 millirem per week.

At one point I had read that

At one point I had read that SLO milk is constantly contaminated with I-131 from Diablo Canyon. Don't know if it's true of not, though.

Not that it means much, but

Not that it means much, but there were a number of samples with
nothing detected.

Compared to the latest BRAWM team results

Other than iodine, the CDPH are similar to the latest BRAWM
team results.

Iodine-131 4.14 (0.15 Bq/L) (BRAWM less than MDA)
Cesium-134 4.55 (0.17 Bq/L) (BRAWM 0.16 Bq/L)
Cesium-137 5.11 (0.19 Bq/L) (BRAWM 0.23 Bq/L)

Previous CDPH milk reports

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

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.
