What is an uranium bomb?

Answer 1

• a uranium bomb is a fission bomb using uranium as the fuel
• a plutonium bomb is a fission bomb using plutonium as the fuel
• a composite bomb is a fission bomb using both uranium and plutonium as the fuel
• a 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 yield
• a wet bomb is a fusion bomb using a cryogenic liquid mixture of deuterium/tritium as the fuel
• a dry bomb is a fusion bomb using solid lithium deuteride as the fuel
• a 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 fallout
• a "dirty bomb" or "salted bomb" is a fusion bomb with the uranium-238 radiation casing/tamper replaced with a material intended to increase fallout
• a radiological bomb (sometimes incorrectly called a dirty bomb) is a conventional bomb wrapped in a jacket of radioactive isotopes
• a radiological weapon is a device, not using explosives, designed to disburse a large quantity of radioactive isotopes over a large area

I hope this clarifies some things.

Answer 2

An uranium bomb is a type of nuclear weapon that uses uranium as the main fissionable material. When the uranium is enriched to a high level, it can produce a large amount of energy when its atoms split in a chain reaction, resulting in a powerful explosion.
