The Trinity test on 16 July 1945, near Socorro, New Mexico, was the first-ever test of a nuclear weapon (yield of around 20 kilotons). The Operation Crossroads series in July 1946, at Bikini Atoll in the Marshall Islands , was the first postwar test series and one of the largest military operations in U.S. history.
While nuclear weapons testing did not produce scenarios like nuclear winter as a result of a scenario of a concentrated number of nuclear explosions in a nuclear holocaust, the thousands of tests, hundreds being atmospheric, did nevertheless produce a global fallout that has peaked in 1963 (the Bomb pulse), reaching levels of about 0.15 mSv per ...
