Raw milk update 5/24

5/24 (10:17am): Since we have at this point received several "raw" milk samples, including five from a single farm, we have created a separate page for raw milk results, including plots of that farm's data.

In the process of refining the raw milk data, we found that we accidentally overestimated the Iodine-131 concentrations in raw milk. Our first measurements of raw milk had been reported with levels of I-131 that were much higher than store-bought milk. The root of the problem was that our analysis code accidentally over-corrected for the decay of I-131 in raw milk, and so the activity reported for I-131 was about 5 times too high. We have revised the code to report the correct activity, and the values are on par with the store-bought milk. This includes recent non-detections of I-131, and declining levels of Cs-134 and Cs-137.
