does fusion nuclear reaction produce alpha and jamma ridation or just alpha
Generally, nuclear fusion using tritium-deuterium fuel produces a large amount of neutron radiation, along with some amount of Gamma rays and X-Rays. Alpha particles are produced, but aren't really considered "radiation" since they don't escape the reactor.
for i know that nuclear fusion weapons ..they use D and T as fuel.... but sometimes .. I read they use lithium 6 & lithium 7......does this fuel elements (D T Li) useit all in one bomb or they use each element for each bomb
It depends on the design. Some bombs just use lithium 6-deuteride as a fuel, while others can also include deuterium or tritium gas as well in order to have a "variable yield" weapon.
Does fission nuclear station needs slow neurons in reaction. ....and nuclear fission bombs need fast neutrons..
I believe that is correct.
See here: http://en.wikipedia.org/wiki/Neutron_moderator#Nuclear_weapon_design
what does 3.5 mev and 14.1 mev means.
.....example .....D+T→He3 (3.5mev)+ n (14.1mev) .ist thermal energy power in put or out put..
MeV stands for mega (million) electron volts. An electron volt is used as a measure of energy in this context. The reaction of D-T produces He3 and a neutron which have a kinetic energy of 3.5 MeV and 14.1 MeV respectively. This energy would be the output energy produced from the reaction. So the reaction produces a total of 17.6 MeV's of energy.
can you tell me .what all types isotopes fuels used for each different fusion bombs.
