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 ...
Death is highly likely and radiation poisoning is almost certain if one is caught in the open with no terrain or building masking effects within a radius of 0–3 kilometres (0.0–1.9 mi) from a 1 megaton airburst, and the 50% chance of death from the blast extends out to ~8 kilometres (5.0 mi) from the same 1 megaton atmospheric explosion.

A nuclear electromagnetic pulse (nuclear EMP or NEMP) is a burst of electromagnetic radiation created by a nuclear explosion.The resulting rapidly varying electric and magnetic fields may couple with electrical and electronic systems to produce damaging current and voltage surges.
The energy contained in one megaton of TNT (4.2 PJ) is enough to power the average American household for 103,000 years. [32] The 30 Mt (130 PJ) estimated upper limit blast power of the Tunguska event could power the same average home for more than 3,100,000 years. The energy of that blast could power the entire United States for 3.27 days. [33]
For a 10-kiloton blast — equivalent to two-thirds of the Hiroshima bomb blast, or 5,000 Oklahoma City truck bombings — that's about a half-mile radius. ... 50 must-have tech accessories under $50.
Using a combination of explosive wave-shaping and "gun-barrel" design, up to 5% of a small nuclear bomb could reportedly be converted into kinetic energy driving a beam of particles with a beam angle of 0.001 radians (0.057 degrees), far more concentrated than the earlier-proposed plasma jet, though this decreases to 1% efficiency at 50 ...
A B83 casing. The B83 is a variable-yield thermonuclear gravity bomb developed by the United States in the late 1970s that entered service in 1983. With a maximum yield of 1.2 megatonnes of TNT (5.0 PJ), it has been the most powerful nuclear weapon in the United States nuclear arsenal since October 25, 2011 after retirement of the B53. [1]
Some variable yield nuclear warheads such as the B61 nuclear bomb have been produced in both tactical and strategic versions. Whereas the lowest selectable yield of a tactical B61 (Mod 3 and Mod 4) is 0.3 kilotons (300 tons), [ 19 ] modern PAL mechanisms ensure that centralized political control is maintained over each weapon, including their ...
