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 ...
First nuclear weapons test, conducted as part of the Manhattan Project. Tested the Mark 3 Fat Man design. Crossroads: 1946 2: 2: 2: 21 42: First postwar test series.

The People's Republic of China conducted 45 tests (23 atmospheric and 22 underground, all conducted at Lop Nur Nuclear Weapons Test Base, in Malan, Xinjiang) 596 First test – October 16, 1964; Film is now available of 1966 tests here at time 09:00 [24] and another test later in this film. Test No. 6, First hydrogen bomb test – June 17, 1967
Underground nuclear testing is the test detonation of nuclear weapons that is performed underground. When the device being tested is buried at sufficient depth, the nuclear explosion may be contained, with no release of radioactive materials to the atmosphere.
The test weapons produced a combined yield of about 77-78.6 Mt of TNT in explosive power. After the inhabitants agreed to a temporary evacuation, to allow nuclear testing on Bikini, which they were told was of great importance to humankind, [3] two nuclear weapons were detonated in 1946. About ten years later, additional tests with ...
In order to better understand the blast and thermal effects of a nuclear bomb, the US dropped a 16-kiloton bomb on a fake town in the middle of Nevada. Creepy photos show a fake 1950s city filled ...
The United States nuclear program since its inception has experienced accidents of varying forms, ranging from single-casualty research experiments (such as that of Louis Slotin during the Manhattan Project), to the nuclear fallout dispersion of the Castle Bravo shot in 1954, to accidents such as crashes of aircraft carrying nuclear weapons ...
The MET was the first bomb core to include uranium-233 (a rarely used fissile isotope that is the product of thorium-232 neutron absorption), along with plutonium; this was based on the plutonium/U-235 pit from the TX-7E, a prototype Mark 7 nuclear bomb design used in the 1951 Operation Buster-Jangle Easy test.
