This form of radioactive contamination is known as nuclear fallout and poses the primary risk of exposure to ionizing radiation for a large nuclear weapon. Details of nuclear weapon design also affect neutron emission: the gun-type assembly Little Boy leaked far more neutrons than the implosion-type 21 kt Fat Man because the light hydrogen ...
Theoretically, a tectonic weapon functions by creating a powerful charge of elastic energy in the form of deformed volume of the Earth's crust in a region of tectonic activity. [2] This then becomes an earthquake once triggered by a nuclear explosion in the epicenter or a vast electric pulse. [2]

Later in the war, Barnes Wallis made bombs based on the "earthquake bomb concept", such as the 6-ton Tallboy and then the 10-ton Grand Slam, although these were never dropped from more than about 25,000 feet (7.6 km). Even from this relatively low altitude, the earthquake bomb had the ability to disrupt German industry while causing minimum ...
The plant supplies 6% of California's power, but carries a 1 in 37,000 chance of experiencing a Chernobyl-style nuclear meltdown within five years. ... In the event of an earthquake, they need to ...
Nuclear weapons materials on the black market are a global concern, [48] [49] and there is concern about the possible detonation of a small, crude nuclear weapon or dirty bomb by a militant group in a major city, causing significant loss of life and property. [50] [51] The number and sophistication of cyber attacks is on the rise.
The Cold War ended in 1991, but the looming threat of nuclear attack lives on with more than 14,900 nuclear weapons wielded by nine nations.. A terrorist-caused nuclear detonation is one of 15 ...
A nuclear weapon [a] is an explosive device that derives its destructive force from nuclear reactions, either fission (fission or atomic bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter.
