At the height of the , thousands of U.S. and Soviet ballistic missiles on were capable of delivering up to 10 at a time, each one twenty times more powerful than the Hiroshima bomb. Though decades of agreements have slowly reduced the size of their arsenals, nuclear weapon States still possess the capability to destroy each other many times over.

Administered by the U.S., this island was used for nuclear testing in the late 1940's and 50's. Bikini Atoll was the site of BRAVO test.
The largest nuclear explosion in history was the 1961 Soviet “Tsar Bomba” test, which measured more than 50 (3,800 times more powerful than the Hiroshima bomb). To generate an explosion of this magnitude using dynamite, it would require 50 billion kilograms (over 110 billion pounds) of TNT, which is more than the weight of all the cargo that has passed through London’s Heathrow airport in the past 40 years. Expressed in volume, this would amount to 18 blocks of TNT each as large as the Empire State building.

Nuclear weapons have been tested in all environments since 1945: in the atmosphere, underground and underwater. Tests have been carried out onboard barges, on top of towers, suspended from balloons, on the Earth’s surface, more than 600 metres underwater and over 200 metres underground. Nuclear test bombs have also been dropped by aircraft and fired by rockets up to 320 km into the atmosphere.

The first nuclear test was carried out by the United States in July 1945, followed by the Soviet Union in 1949, the United Kingdom in 1952, France in 1960, and China in 1964. The National Resources Defense Council estimated the total yield of all nuclear tests conducted between 1945 and 1980 at 510 megatons (Mt). Atmospheric tests alone accounted for 428 mt, equivalent to over 29,000 Hiroshima size bombs.

The generated by a nuclear explosion can vary considerably depending upon a number of factors. These include the size of the weapon and the location of the burst. An explosion at ground level may be expected to generate more dust and other radioactive particulate matters than an air burst. The dispersion of radioactive material is also dependent upon weather conditions.
