Laboratory Data from Milk Sample Analysis
The milk sampling results are far below the Food and Drug Administration's Derived Intervention Level for iodine-131 in milk. These types of findings are to be expected in the coming days and are far below levels of public health concern, including for infants and children. Iodine-131 has a very short half-life of approximately eight days, and the level detected in milk and milk products is therefore expected to drop relatively quickly.
