Fission weapons use either uranium or plutonium. Both of these elements are radioactive, though the radiation is not what precipitates the nuclear reaction. So to answer the question, very little.
Radioactivity more precisely fission chain reaction
physicist who studied radioactivity and nuclear physics. She was part of the team that discovered nuclear fission, for which Otto Hahn received a Nobel Prize.
There are many types of nuclear radiation that have nothing to do with bombs, reactors, etc. In fact most radioactive material on earth was formed in supernovas billions of years before our solar system even formed. The materials used to make the active components of nuclear explosives are radioactive, however the designers of such explosives state that this radioactivity actually makes it harder to build reliable explosives. This radioactivity causes predetonation fizzles in fission bomb designs and aging/wear-out problems in all bomb designs. Another problem with radioactivity in nuclear weapons is the exposure hazard to personnel. For example the US Navy uses what is called Super Grade Plutonium, that has much less Plutonium-240 which is a strong gamma emitter than standard weapons Plutonium, in all their weapons that is very expensive to make. The principles used in nuclear explosives are nuclear fission and nuclear fusion.
Not sure what sort of cloud you are referring to. Nuclear reactions release energy as heat and as radioactivity.
Reactors use thermal (slow) neutrons, fission weapons use fast neutrons.Reactors all use fission, weapons can use fission, fusion, or any combination.Reactors can use delayed fissions making them respond slowly to control changes, weapons complete their reaction too fast for delayed fissions to happen.Reactors have control rods and their energy release can be adjusted or even turned off, weapons have no controls and release all their energy in a few microseconds once triggered.etc.
Uranium mainlyPlutonium and Uranium in fission weapons, Lithium deuteride in fusion weapons, occasionally small amounts of Tritium gas to boost fission weapons with fusion.
Practically all the isotopes obtained by the nuclear fission of uranium are artificial radioactive isotope.
fission bomb no, fusion bomb yes.
Radioactivity more precisely fission chain reaction
Nuclear weapons
nuclear plants because the fission reaction releases lots of radioactive particles causing radioactivity..
Some famous implode systems include but are not limited to nuclear weapon design, pure fission weapons, boosted fission weapons, two-stage thermonuclear weapons and pure fusion weapons to name some.

Both are used.
The atom bomb
Einsteinium isotopes can emit alpha particles, beta particles, positrons; spontaneous fission is also possible.
Types of Nuclear WeaponsThere are at least three types of nuclear weapons: Pure fission, combined fission/fusion, and cobalt.
