Materials needed to make an atomic bomb are:
fissionable material (Plutonium239 isotope)
explosive to start the nuclear chain reaction (TNT, Gelignite or semtex)
detonator
pusher (made from aluminium, beryllium)
To build an atomic bomb, highly enriched uranium or plutonium is typically used as the fissile material. Other components include explosives to trigger the reaction, as well as sophisticated engineering to ensure a successful detonation. The design and construction of an atomic bomb also require specialized knowledge and expertise in nuclear physics and engineering.
In simple terms, an atom bomb is a device containing pieces of fission material at sub-critical masses (self-sustaining chain reaction cannot occur). When the bomb is activated, the pieces are brought together into critical or super-critical mass so that a self-sustaining chain reaction can occur. Two models of making this happen are the gun model and the implosion model. The gun model shoots a piece of fission material into another piece, producing super-critical mass. The implosion model uses an explosive to compress the fission material to critical density.
In general, a fusion bomb (hydrogen bomb) is more powerful than a fission (atomic) bomb. Fusion bombs use an atomic bomb to begin the fusion reaction.
There are multiple atomic bombs in existence, not just three. The title "Junior" is not commonly used in reference to a specific atomic bomb. Each weapon is typically given a unique code name or designation by the governing authority.
I suggest Richard Rhodes book The Making of the Atomic Bomb.
atomic bomb
No, the atomic bomb relies on the process of nuclear fission, which produces radioactivity as a byproduct. Radioactivity is essential for the explosive power of the bomb.
no
the Nazi didn't build the atomic bomb the Americans did....
To defend against a possible Nazi atomic bomb!
1945
No, they designed but did not build them.
No, Thomas Edison did not build the atomic bomb. The atomic bomb was developed during World War II by the Manhattan Project team led by scientists such as J. Robert Oppenheimer and Enrico Fermi. Edison was a prolific inventor known for his work in electricity and the light bulb.
the first atomic bomb.......................................
The fear that Germany was already well on the way to building an atomic bomb and could make first use of them against either England or the USSR at any moment.
the Manhattan project
Yes, that was its codename.
Manhattan Project
It takes very little time to build an atomic bomb, once a country has the necessary industrial infrastructure to produce the fissile material.
