How big is a nuclear explosion?

idk just wondering:)



You have asked a poorly defined question.





It's like saying, "How long is a rope?"





Anyway.





All of the explosions that we have made so far have been no bigger than the equivalent of 50 to 60 million tonnes of TNT.





Of course, larger explosions are possible. Novae, and supernovae are incomporably larger, and are very definitely 'nuclear'.




Biggest frikin nuclear bomb..............


The Tsar Bomba was a three-stage hydrogen bomb with a yield of about 50 megatons. Exploded October 30, 1961 on Novaya Zemlya Island in the Arctic Sea.The fireball touched the ground, reached nearly as high as the altitude of the release plane, and was seen and felt almost 1,000 kilometres (620 mi) from ground zero. The heat from the explosion could have caused third degree burns 100 km (62 miles) away from ground zero. The subsequent mushroom cloud was about 64 kilometres (40 mi) high (nearly seven times higher than Mount Everest) and 40 kilometres (25 mi) wide. The explosion could be seen and felt in Finland, even breaking windows there. Atmospheric focusing caused blast damage up to 1,000 kilometres (620 mi) away. The seismic shock created by the detonation was measurable even on its third passage around the Earth. Its Richter magnitude was about 5 to 5.25.




Which nuclear explosion do you mean? There is no one size of nuclear explosion. This is like asking how large is a boat - they come in all sizes.





Human-made nuclear explosions are usually measured in the kilotons (the amount of TNT it would take to create the same explosive force).


For example, the Hiroshima bomb was about 15 kilotons.




The actual explosion occurs in a critical mass of uranium only a few inches in diameter. Everything after that is just expanding hot gasses.




H-bombs are about a thousand times more powerful than the Hiroshima and Nagasaki bombs, and will destroy almost everything within a 15 mile radius and kill by radioactive fallout over an area of hundreds of square miles.




I think the bombs were exploded at 10,000 ft. to destroy the cities below. Still nothing compared to the H-Bomb.
