High concentrations of radioiodine in milk, found preferentially over the midwestern United States after atmospheric nuclear tests in May 1962, 1965, and 1966, can best be explained by high-reaching intense thunderstorms that scavenge passing radioactivity from the upper troposphere and lower stratosphere.
