The key ingredient in a nuclear bomb is enriched uranium ā or plutonium, which can be obtained through the combustion of uranium. … Natural uranium is composed of uranium-238, which makes up 99.3 percent, and uranium-235, the remaining 0.7 percent. Only uranium-235, called “fissile uranium,” can be used for nuclear fuel.

What does a neutron bomb do to humans? Upon detonation, a near-ground airburst of a 1 kiloton neutron bomb would produce a large blast wave and a powerful pulse of both thermal radiation and ionizing radiation in the form of fast (14.1 MeV) neutrons. The thermal pulse would cause third degree burns to unprotected skin out to approximately 500 meters.
Keeping this in consideration, Why US dropped nuclear bomb on Japan?
