The Nagasaki BombĬompared to the one used on Hiroshima, the Nagasaki bomb was rounder and fatter. It is believed that the fission of slightly less than one kilogram of uranium 235 released energy equivalent to approximately 15,000 tons of TNT. Devastation in Hiroshimaĭue to its long, thin shape, the Hiroshima bomb was called ‘Little Boy’.
This chain reaction spreads almost instantaneously.Ītomic bombs were exploded in war in Hiroshima and Nagasaki at the end of World War II. Energy is released when those neutrons split off from the nucleus, and the newly released neutrons strike other uranium or plutonium nuclei, splitting them in the same way, releasing more energy and more neutrons.
#FISSION BOMB FREE#
When a single free neutron strikes the nucleus of an atom of radioactive material like uranium or plutonium, it knocks two or three more neutrons free. Nuclear fission produces the atomic bomb, a weapon of mass destruction that uses power released by the splitting of atomic nuclei. Nuclear fusion – two smaller atoms are brought together, usually hydrogen or hydrogen isotopes (deuterium, tritium), to form a larger one (helium isotopes) this is how the sun produces energy.This method usually involves isotopes of uranium (uranium-235, uranium-233) or plutonium (plutonium-239). Nuclear fission – the nucleus of an atom is split into two smaller fragments by a neutron.
There are two ways that nuclear energy can be released from an atom:
