The level found of I-131 in Phoenix milk was 3.2 Litre (pCi/L).
This level exceeds the federal limit for I-131 in drinking water, at least as reported by Business Insider at 3 pCi/L
Information on other forms of radiation that might also be present was not available.
A website linked below that interprets the contamination data found and published by the UC Berkeley nuclear engineering lab found a high of 5.9 pCi/L which they translated into a 0.011 mRem dose for an infanthttp://www.idealist.ws/contaminationna.php
Keep in mind that the effects of radiation from internal emitters is very different from the external exposure of having an XRay or flying in an airplane. I would be concerned about giving milk to small children if elevated levels of radiation continue to contaminate our milk. The
Physicians for Social Responsibility have clearly stated that there is no level fo safe exposure for radiation, particularly when consumed and particularly for children.
