TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
Hiroshima Prefectural Industrial Promotion Hall, the closest surviving building to the location of the bomb's detonation, was designated the Hiroshima Peace Memorial. The Hiroshima Peace Memorial Museum was opened in 1955 in the Peace Park. [318] Hiroshima also contains a Peace Pagoda, built in 1966 by Nipponzan-Myōhōji-Daisanga. [319]
Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene ...
On August 6, 1945, the United States became the first an only nation to use an atomic weapon during war when Enola Gay -- an American bomber -- dropped a five-ton atomic bomb on the Japanese city ...
Little Boy was a type of atomic bomb created by the United States as part of the Manhattan Project during World War II.The name is also often used to describe the specific bomb (L-11) used in the bombing of the Japanese city of Hiroshima by the Boeing B-29 Superfortress Enola Gay on 6 August 1945, making it the first nuclear weapon used in warfare, and the second nuclear explosion in history ...
On August 6, 2018, the 73rd anniversary of the bombing of Hiroshima, residents will pause to remember the day in 1945 that changed the course of history.
The Little Boy gun-type atomic bomb dropped on Hiroshima on August 6, 1945, was made of highly enriched uranium with a large tamper. The nominal spherical critical mass for an untampered 235 U nuclear weapon is 56 kilograms (123 lb), [ 6 ] which would form a sphere 17.32 centimetres (6.82 in) in diameter.
Dazed survivors immediately feared that the explosion was the result of a bomb dropped from a German plane. [84] Troops at gun batteries and barracks immediately turned out in case the city was under attack, but within an hour switched from defence to rescue roles as the cause and location of the explosion were determined.
