Milk update (4/9/2012)

4/9/2012 (5:45pm): Three recent milk test results have been posted on the milk sample page with "best by" dates of 3/12, 4/9, and 4/16. Very low levels of Cs-134 and Cs-137 were detected in the samples — the amounts are so small that it would require drinking over tens of thousands of liters of milk to receive the small dose that one receives from a cross-country airplane flight. These isotopes can still be detected in milk because they have long half-lives (2 years and 30 years, respectively) and therefore trace amounts will remain in the grass and hay that the cows feed on.
