Although poll data reported in the New York Times (2016) indicates that many Americans viewed the 1950s as the time when America was at its greatest, during this time between 1945-1959 approximately 200 nuclear bombs were tested above ground (atmospheric testing) on US soil.  These atomic bombs produced radioactive fallout which--in this case--drifted from the test sites in western Nevada eastward to New York, Connecticut, Rhode Island, Massachusetts, Vermont, New Hampshire and Maine.  The radioactive fallout got into food sources, such as milk, which was consumed by the population.  
This series, titled Nuclear Families, explores the dichotomy between the willful blindness of the US Government to the effects of atmospheric atomic testing and the post-war optimism of white America.
