A simple count of the number of warheads, as shown in the previous chart, does not consider that these weapons differ in their explosive power. It also does not consider that not all of them can be used at once. The data shown in the following chart attempts to take this into account. It considers the destructiveness and deployment of nuclear warhe...
The nuclear weapons states frequently tested their warheads in the past, but tests now have almost ended. The chart shows that they peaked in 1962 at 178 tests, mostly conducted by the United States and the Soviet Union. These tests harmedthe environment and people, especially indigenous communities. Tests decreased later during the Cold War and ha...
