It was both: an atomic bomb using uranium as its fuel.
Hiroshima bomb: uranium Nagasaki bomb: plutonium
A bomb containing highly enriched uranium (in the isotope 235U) as explosive.
atomic
Yes,well and truly it was.In fact,a uranium bomb is one of a rare bomb made.
a uranium bomb is a fission bomb using uranium as the fuela plutonium bomb is a fission bomb using plutonium as the fuela composite bomb is a fission bomb using both uranium and plutonium as the fuela levitated core bomb is a fission bomb with an air gap between the uranium-238 tamper and the fuel core to increase compression of the fuel, efficiency, and yielda wet bomb is a fusion bomb using a cryogenic liquid mixture of deuterium/tritium as the fuela dry bomb is a fusion bomb using solid lithium deuteride as the fuela boosted bomb is a fission bomb using a tritium gas fusion "booster"a "clean bomb" is a fusion bomb with the uranium-238 radiation casing/tamper replaced with a material intended to reduce fallouta "dirty bomb" or "salted bomb" is a fusion bomb with the uranium-238 radiation casing/tamper replaced with a material intended to increase fallouta radiological bomb (sometimes incorrectly called a dirty bomb) is a conventional bomb wrapped in a jacket of radioactive isotopesa radiological weapon is a device, not using explosives, designed to disburse a large quantity of radioactive isotopes over a large areaI hope this clarifies some things.
Atom Bomb = Uranium H-Bomb = Hydrogen
The uranium used for the atomic bomb was primarily sourced from the Congo and later from mines in the US. The uranium ore was then processed to extract the isotope U-235 necessary for nuclear fission to create the bomb.
Uranium-235 and plutonium-239 were the two radioactive elements chosen for the atomic bomb dropped on Hiroshima and Nagasaki.
