Nuclear weapons tests are experiments carried out to determine the performance, yield, and effects of nuclear weapons. Testing nuclear weapons offers practical information about how the weapons function, how detonations are affected by different conditions, and how personnel, structures, and equipment are affected when subjected to nuclear ...

Now 86, Mr Morris is one of the last few of 22,000 personnel who witnessed the UK’s nuclear bomb tests - and those that are able to are still fighting to find out what it did their bodies.
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 medical effects of the atomic bomb upon humans can be put into the four categories below, with the effects of larger thermonuclear weapons producing blast and thermal effects so large that there would be a negligible number of survivors close enough to the center of the blast who would experience prompt/acute radiation effects, which were observed after the 16 kiloton yield Hiroshima bomb ...
However, there was still a large amount of worldwide nuclear testing until the end of the Cold War in the early 1990s. [24] Afterwards, the Comprehensive Test Ban Treaty was signed and ratified by the major nuclear weapons powers, and the number of worldwide nuclear tests decreased rapidly. [ 24 ]
It tested its first hydrogen bomb ("Test No. 6") in 1967, 32 months after testing its first nuclear weapon (the shortest fission-to-fusion development known in history). [62] China is the only NPT nuclear-weapon state to give an unqualified negative security assurance with its " no first use " policy.
