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.
The map will show the blast radius broken down into fireball, air blast and thermal radiation area. The program will calculate the number of casualties based on how many people live in the ...
A kiloton of TNT can be visualized as a cube of TNT 8.46 metres (27.8 ft) on a side. The "megaton (of TNT equivalent)" is a unit of energy equal to 4.184 petajoules (4.184 × 10 15 J). [3] The kiloton and megaton of TNT equivalent have traditionally been used to describe the energy output, and hence the destructive power, of a nuclear weapon.
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. But even in a 100-kiloton explosion ...
Sycamore, a clean test, was a fizzle, producing only 92 kilotonnes of TNT (380 TJ) instead of the predicted 5 megatonnes of TNT (21 PJ). Poplar was a retest of Sycamore with a predicted yield of 5 to 10 megatonnes of TNT (21 to 42 PJ) and only 200 kilotonnes of TNT (840 TJ) fission yield. The actual yield was 9.3 megatonnes of TNT (39 PJ).
A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device.
This relatively poor accuracy required a big, civilization-smothering warhead to make up for it; as a result, each missile carried one megaton thermonuclear warhead or three individual 200-kiloton ...
