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 ...
A one-kiloton explosion is equivalent to detonating one-thousand tons of TNT, also a one-megaton is equivalent of one-million tons of TNT. The explosion of one ton of TNT releases approximatly 4.2 × 10 12 joules of energy; for comparison, it takes almost 6.0 ×10 4 joules to warm up a cup of coffee.
The atomic bombs used on Hiroshima and Nagasaki were fission weapons. The nuclei of atoms consist of protons and neutrons, with the number of protons determining the element (e.g., carbon has 6 protons, while uranium has 92) and the number of neutrons determining the isotope of that element.
23 Δεκ 2013 · What makes nuclear weapons impressive and terrible is that their default yield-to-weight ratio — that is, the amount of bang per mass, usually expressed in terms of kilotons per kilogram (kt/kg) — is much, much higher than conventional explosives. Take TNT for example.
A nuclear weapon is a explosive device that uses a controlled uncontrolled nuclear chain reac4on to release huge amounts of energy. Nuclear weapons make use of one or two forms of interac4ons between atoms: Fission: uses a neutron to split a nucleus to release neutrons that split more nuclei to create a supercri4cal fission process.
• 1-kiloton nuclear weapon is one, which produces the same amount of energy in an explosion, as does 1 kiloton (1,000 tons) of TNT. • 1-megaton weapon would have the energy equivalent of 1 million tons of TNT. One megaton is equivalent to 4.18 x 1015 joules.
Even a crude nuclear device that fizzled would destroy many square kilometers of a city and kill tens of thousands of people. A large (1 megaton) nuclear weapon could kill millions of people and destroy hundreds of square kilometers within a few seconds.
