The FDA found small amounts of radiation in a sample batch of milk from Spokane, Washington. The level, however, was 5,000 times lower than the Derived Intervention Level set by the FDA.
People - including infants and children -- who drank this barely contaminated milk will be fine; undergoing medical x-rays, especially extensive ones like a full-body CT scan, will actually expose individuals to much more radiation than drinking the milk.
In Tokyo, radiation leakages and poisoning in food and tap water are legitimate concerns due to the city's proximity to the leaking power plants. In the US, however, such fears are overblown.
Nevertheless, Japan's nuclear crisis captured the attention of the world and sparked global debates about nuclear safety. In Germany, such concerns have already been credited with the election victories of a party that was against nuclear power usage.
