Americans are typically told the story of the scientists who built the atomic bomb as an intellectual race for the world’s most powerful weapon during wartime.
More than 100 atmospheric weapons tests were conducted in the U.S. and its territories between 1945 and 1962. It resulted in widespread radioactive fallout across much of the U.S., largely spread by prevailing winds and rain. In addition, contaminated waste was shipped and haphazardly stored across the country, creating new toxic Superfund sites stretching from Colorado to New York.
