There have been reports of radioactive iodine being found in small amounts in the milk of west coast dairy cows; the small amounts have been reported as a good sign. If the radioiodine found was actually Iodine 123, (as I suspected rained on Saint Louis 3/29/11) it could be a very bad sign. I123 has a very short half life of 13 hours. By the time the milk test results would have come back, most of the Iodine 123 would have decayed.
Instead of only reporting the results of the milk tests, public health officials should be testing and reporting bovine thyroid iodine concentrations.
They should be checking the cows that have tested positive, for thyroid function They should be checking the milk for decay particles like tellurium 123 that would help identify the type and initial exposure to radioiodines like I123.
Considering that these exposed milk cows are most likely grain fed, much like humans, their exposure to radioactive iodine would have been through inhalation and skin absorption. If some public health agency is not testing these cows for thyroid damage and function, they are either dangerously flat on their asses or there is something they don't want to find.
