ShareToday, that changes thanks to the work of Sébastien Philippe at Princeton University and colleagues. This team have used a state-of-the art weather simulation for the 5 days after each nuclear test to simulate how the fallout would have dispersed.
The result is the highest resolution estimate ever made of the spread of radioactive fallout across the U.S. It marks the start of the Anthropocene with extraordinary precision and it throws up some significant surprises. Some parts of the U.S. are known to have received high levels of fallout and the new work is consistent with this. But the research also reveals some parts of the US that received significant fallout without anybody realizing.
The findings “provide an opportunity for re-evaluating the public health and environmental implications from atmospheric nuclear testing,” say Philippe and co. Between 1945 and 1962, the U.S. conducted 94 atmospheric nuclear tests that generated yields of up to 74 kilotons of TNT. (Seven other tests were damp squibs.) 93 of these tests took place in Nevada but the first, the Trinity test in the Oppenheimer film, took place in New Mexico. (Read more.)
