Radiation Isn't Only in the Ocean!
Cesium-137 was found in milk from Vermont. The sample contained 1.9 picoCuries per liter of cesium-13 which is the maximum contamination level set by the EPA8.
Radioactive isotopes accumulate in milk and are spead by rain or wind and settle on vegetation, where they are ingested by grazing cattle. Iodine-131 can accumulate in the thyroid gland, and can cause cancer and other thyroid diseases. Cesium-137 accumulates in the body’s soft tissues, where it increases risk of cancer, according to EPA8.
