During the Cold War the United States detonated hundreds of atomic weapons at the Nevada Test Site. Many of these nuclear tests were conducted above ground and released tremendous amounts of radioactive pollution into the environment. This paper combines a novel dataset measuring annual county level fallout patterns for the continental U.S. with vital statistics records. I find that fallout from nuclear testing led to persistent and substantial increases in overall mortality for large portions of the country. The cumulative number of excess deaths attributable to these tests is comparable to the bombings of Hiroshima and Nagasaki.
Basically he combines mortality estimates with measures of Iodine-131 concentrations in locally produced milk, “to provide a more precise estimate of human exposure to fallout than previous studies.” The most significant effects are in the Great Plains and Central Northwest of America, and “Back-of-the-envelope estimates suggest that fallout from nuclear testing contributed between 340,000 to 460,000 excess deaths from 1951 to 1973.”
His primary job market paper is on damage to agriculture from nuclear testing.
